What Is OpenFlow and How Does It Work?

Share

OpenFlow is a communication protocol originally introduced by researchers at Stanford University in 2008. It allows the control plane to interact with the forwarding plane of a network device, such as a switch or router.

OpenFlow separates the forwarding plane from the control plane. This separation allows for more flexible and programmable network configurations, making it easier to manage and optimize network traffic. Think of it like a traffic cop directing cars at an intersection. OpenFlow is like the communication protocol that allows the traffic cop (control plane) to instruct the cars (forwarding plane) where to go based on dynamic conditions.

How Does OpenFlow Relate to SDN?

OpenFlow is often considered one of the key protocols within the broader SDN framework. Software-Defined Networking (SDN) is an architectural approach to networking that aims to make networks more flexible, programmable, and responsive to the dynamic needs of applications and services. In a traditional network, the control plane (deciding how data should be forwarded) and the data plane (actually forwarding the data) are tightly integrated into the network devices. SDN decouples these planes, and OpenFlow plays a crucial role in enabling this separation.

OpenFlow provides a standardized way for the SDN controller to communicate with the network devices. The controller uses OpenFlow to send instructions to the switches, specifying how they should forward or process packets. This separation allows for more dynamic and programmable network management, as administrators can control the network behavior centrally without having to configure each individual device.

How Does OpenFlow Work?

The OpenFlow architecture consists of controllers, network devices and secure channels. Here’s a simplified overview of how OpenFlow operates

Controller-Device Communication:

  • An SDN controller communicates with network devices (usually switches) using the OpenFlow protocol.
  • This communication is typically over a secure channel, often using the OpenFlow over TLS (Transport Layer Security) for added security.

Flow Table Entries:

  • An OpenFlow switch maintains a flow table that contains information about how to handle different types of network traffic. Each entry in the flow table is a combination of match fields and corresponding actions.

Packet Matching:

  • When a packet enters the OpenFlow switch, the switch examines the packet header and matches it against the entries in its flow table.
  • The match fields in a flow table entry specify the criteria for matching a packet (e.g., source and destination IP addresses, protocol type).

Flow Table Lookup:

  • The switch performs a lookup in its flow table to find the matching entry for the incoming packet.

Actions:

  • Once a match is found, the corresponding actions in the flow table entry are executed. Actions can include forwarding the packet to a specific port, modifying the packet header, or sending it to the controller for further processing.

Controller Decision:

  • If the packet doesn’t match any existing entry in the flow table (a “miss”), the switch can either drop the packet or send it to the controller for a decision.
  • The controller, based on its global view of the network and application requirements, can then decide how to handle the packet and send instructions back to the switch.

Dynamic Configuration:

Administrators can dynamically configure the flow table entries on OpenFlow switches through the SDN controller. This allows for on-the-fly adjustments to network behavior without manual reconfiguration of individual devices.

Networking Research Laboratory

OpenFlow provides a platform for simulating and emulating complex network scenarios. Researchers can recreate diverse network environments, including large-scale topologies and various traffic patterns, to study the behavior of their proposed solutions. Its programmable and centralized approach makes it an ideal platform for researchers to explore and test new protocols, algorithms, and network architectures.

In conclusion, OpenFlow has emerged as a linchpin in the world of networking, enabling the dynamic, programmable, and centralized control that is the hallmark of SDN. Its diverse applications make it a crucial technology for organizations seeking agile and responsive network solutions in the face of evolving demands. As the networking landscape continues to evolve, OpenFlow stands as a testament to the power of innovation in reshaping how we approach and manage our digital connections.

What Is Network Edge?

Share

The concept of the network edge has gained prominence with the rise of edge computing, which involves processing data closer to the source of data generation rather than relying solely on centralized cloud servers. This approach can reduce latency, improve efficiency, and enhance the overall performance of applications and services. In this article, we’ll introduce what the network edge is, explore how it differs from edge computing, and describe the benefits that network edge brings to enterprise data environments.

What is Network Edge?

At its essence, the network edge represents the outer periphery of a network. It’s the gateway where end-user devices, local networks, and peripheral devices connect to the broader infrastructure, such as the internet. It’s the point at which a user or device accesses the network or the point where data leaves the network to reach its destination. the network edge is the boundary between a local network and the broader network infrastructure, and it plays a crucial role in data transmission and connectivity, especially in the context of emerging technologies like edge computing.

What is Edge Computing and How Does It Differ from Network Edge?

The terms “network edge” and “edge computing” are related concepts, but they refer to different aspects of the technology landscape.

What is Edge Computing?

Edge computing is a distributed computing paradigm that involves processing data near the source of data generation rather than relying on a centralized cloud-based system. In traditional computing architectures, data is typically sent to a centralized data center or cloud for processing and analysis. However, with edge computing, the processing is performed closer to the “edge” of the network, where the data is generated. Edge computing complements traditional cloud computing by extending computational capabilities to the edge of the network, offering a more distributed and responsive infrastructure.

What is the Difference Between Edge Computing and Network Edge?

While the network edge and edge computing share a proximity in their focus on the periphery of the network, they address distinct aspects of the technological landscape. The network edge is primarily concerned with connectivity and access, and it doesn’t specifically imply data processing or computation. Edge computing often leverages the network edge to achieve distributed computing, low-latency processing and efficient utilization of resources for tasks such as data analysis, decision-making, and real-time response.

Network Edge vs. Edge Computing

Network Edge vs. Network Core: What’s the Difference?

Another common source of confusion is discerning the difference between the network edge and the network core.

What is Network Core?

The network core, also known as the backbone network, is the central part of a telecommunications network that provides the primary pathway for data traffic. It serves as the main infrastructure for transmitting data between different network segments, such as from one city to another or between major data centers. The network core is responsible for long-distance, high-capacity data transport, ensuring that information can flow efficiently across the entire network.

What is the Difference between the Network Edge and the Network Core?

The network edge is where end-users and local networks connect to the broader infrastructure, and edge computing involves processing data closer to the source, the network core is the backbone that facilitates the long-distance transmission of data between different edges, locations, or network segments. It is a critical component in the architecture of large-scale telecommunications and internet systems.

Advantages of Network Edge in Enterprise Data Environments

Let’s turn our attention to the practical implications of edge networking in enterprise data environments.

Efficient IoT Deployments

In the realm of the Internet of Things (IoT), where devices generate copious amounts of data, edge networking shines. It optimizes the processing of IoT data locally, reducing the load on central servers and improving overall efficiency.

Improved Application Performance

Edge networking enhances the performance of applications by processing data closer to the point of use. This results in faster application response times, contributing to improved user satisfaction and productivity.

Enhanced Reliability

Edge networks are designed for resilience. Even if connectivity to the central cloud is lost, local processing and communication at the edge can continue to operate independently, ensuring continuous availability of critical services.

Reduced Network Costs

Local processing in edge networks diminishes the need for transmitting large volumes of data over the network. This not only optimizes bandwidth usage but also contributes to cost savings in network infrastructure.

Privacy and Security

Some sensitive data can be processed locally at the edge, addressing privacy and security concerns by minimizing the transmission of sensitive information over the network. Improved data privacy and security compliance, especially in industries with stringent regulations.

In this era of digital transformation, the network edge stands as a gateway to a more connected, efficient, and responsive future.

100G NIC: An Irresistible Trend in Next-Generation 400G Data Center

Share

NIC, short for network interface card, which can be called network interface controller, network adapter or LAN adapter, allows a networking device to communicate with other networking devices. Without NIC, networking can hardly be done. There are NICs with different types and speeds, such as wireless and wired NIC, from 10G to 100G. Among them, 100G NIC, as a product appearing in recent years, hasn’t taken a large market share yet. This post gives a description of 100G NIC and the trends in NIC as follows.

What Is 100G NIC?

NIC is installed on a computer and used for communicating over a network with another computer, server or other network devices. It comes in many different forms but there are two main different types of NIC: wired NIC and wireless NIC. Wireless NICs use wireless technologies to access the network, while wired NICs use DAC cable or transceiver and fiber patch cable. The most popular wired LAN technology is Ethernet. In terms of its application field, it can be divided into computer NIC card and server NIC card. For client computers, one NIC is needed in most cases. However, for servers, it makes sense to use more than one NIC to meet the demand for handling more network traffic. Generally, one NIC has one network interface, but there are still some server NICs that have two or more interfaces built in a single card.

Figure 1: FS 100G NIC

With the expanding of data center from 10G to 100G, 25G server NIC has gained a firm foothold in the NIC market. In the meantime, the growth in demand for bandwidth is driving data center to higher bandwidth, 200G/400G and 100G transceivers have been widespread, which paves the way for 100G server.

How to Select 100G NIC?

How to choose the best 100G NIC from all the vendors? If you are stuck in this puzzle, see the following section listing recommendations and considerations to consider.

Connector

Connector types like RJ45, LC, FC, SC are commonly used connectors on NIC. You should check the connector type supported by NIC. Today many networks are only using RJ45, so it may be not that hard to choose the NIC for the right connector type as it has been in the past. Even so, some network may utilize a different interface such as coax. Therefore, check if the card you are planning to buy supports this connection before purchasing.

Bus Type

PCI is a hardware bus used for adding internal components to the computer. There are three main PCI bus types used by servers and workstations now: PCI, PCI-X and PCI-E. Among them, PCI is the most conventional one. It has a fixed width of 32 bits and can handle only 5 devices at a time. PCI-X is a higher upgraded version, providing more bandwidth. With the emergence of PCI-E, PCI-X cards are gradually replaced. PCI-E is a serial connection so that devices no longer share bandwidth like they do on a normal bus. Besides, there are different physical sizes of PCI-E card in the market: x16, x8, x4, and x1. Before purchasing a 100G NIC, it is necessary to make sure which PCI version and slot width can be compatible with your current equipment and network environment.

Hot swappable

There are some NICs that can be installed and removed without shutting down the system, which helps minimize downtime by allowing faulty devices to be replaced immediately. While you are choosing your 100G NIC, be sure to check if it supports hot swapping.

Trends in NIC

NICs were commonly used in desktop computers in the 1990s and early 2000s. Up to now, it has been widely used in servers and workstations with different types and rates. With the popularization of wireless networking and WiFi, wireless NICs gradually grows in popularity. However, wired cards are still popular for relatively immobile network devices owing to the reliable connections.NICs have been upgrading for years. As data centers are expanding at an unprecedented pace and driving the need for higher bandwidth between the server and switches, networking is moving from 10G to 25G and even 100G. Companies like Intel and Mellanox have launched their 100G NIC in succession.

During the upgrading from 10G to 100G in data centers, 25G server connectivity popularized for 100G migration can be realized by 4 strands of 25G. 25G NIC is still the mainstream. However, considering the fact that the overall bandwidth for data centers grows quickly and hardware upgrade cycles for data centers occur every two years, the ethernet speed can be faster than we expect. 400G data center is just on the horizon. It stands a good chance that 100G NIC will play an integral role in next-generation 400G networking.

Meanwhile, the need of 100G NIC will drive the demand for other network devices as well. For instance, 100G transceiver, the device between NIC and network, is bound to pervade. Now 100G transceivers are provided by many brands with different types such as CXP, CFP, QSFP28 transceivers,etc. FS supplies a full series of compatible 100G QSFP28 and CFP transceivers that can be matched with the major brand of 100G Ethernet NIC, such as Mellanox and Intel.

Conclusion

Nowadays with the hyping of the next generation cellular technology, 5G, the higher bandwidth is needed for data flow, which paves the way for 100G NIC. On the occasion, 100G transceivers and 400G network switches will be in great need. We believe that the new era of 5G networks will see the popularization of 100G NIC and change towards a new era of network performance.

The Chip Shortage: Current Challenges, Predictions, and Potential Solutions

Share

The COVID-19 pandemic caused several companies to shut down, and the implications were reduced production and altered supply chains. In the tech world, where silicon microchips are the heart of everything electronic, raw material shortage became a barrier to new product creation and development.

During the lockdown periods, some essential workers were required to stay home, which meant chip manufacturing was unavailable for several months. By the time lockdown was lifted and the world embraced the new normal, the rising demand for consumer and business electronics was enough to ripple up the supply chain.

Below, we’ve discussed the challenges associated with the current chip shortage, what to expect moving forward, and the possible interventions necessary to overcome the supply chain constraints.

Challenges Caused by the Current Chip Shortage

As technology and rapid innovation sweeps across industries, semiconductor chips have become an essential part of manufacturing – from devices like switches, wireless routers, computers, and automobiles to basic home appliances.

To understand and quantify the impact this chip shortage has caused spanning the industry, we’ll need to look at some of the most affected sectors. Here’s a quick breakdown of how things have unfolded over the last eighteen months.

Automobile Industry

in North America and Europe had slowed or stopped production due to a lack of computer chips. Major automakers like Tesla, Ford, BMW, and General Motors have all been affected. The major implication is that the global automobile industry will manufacture 4 million fewer cars by the end of 2021 than earlier planned, and it will forfeit an average of $110 billion in revenue.

Consumer Electronics

Consumer electronics such as desktop PCs and smartphones rose in demand throughout the pandemic, thanks to the shift to virtual learning among students and the rise in remote working. At the start of the pandemic, several automakers slashed their vehicle production forecasts before abandoning open semiconductor chip orders. And while the consumer electronics industry stepped in and scooped most of those microchips, the supply couldn’t catch up with the demand.

Data Centers

Most chip fabrication companies like Samsung Foundries, Global Foundries, and TSMC prioritized high-margin orders from PC and data center customers during the pandemic. And while this has given data centers a competitive edge, it isn’t to say that data centers haven’t been affected by the global chip shortage.

Some of the components data centers have struggled to source include those needed to put together their data center switching systems. These include BMC chips, capacitors, resistors, circuit boards, etc. Another challenge is the extended lead times due to wafer and substrate shortages, as well as reduced assembly capacity.

LED Lighting

LED backlights common in most display screens are powered by hard-to-find semiconductor chips. The prices of gadgets with LED lighting features are now highly-priced due to the shortage of raw materials and increased market demand. This is expected to continue up to the beginning of 2022.

Renewable Energy- Solar and Turbines

Renewable energy systems, particularly solar and turbines, rely on semiconductors and sensors to operate. The global supply chain constraints have hurt the industry and even forced some energy solutions manufacturers like Enphase Energy to

Semiconductor Trends: What to Expect Moving Forward

In response to the global chip shortage, several component manufacturers have ramped up production to help mitigate the shortages. However, top electronics and semiconductor manufacturers say the crunch will only worsen before it gets better. Most of these industry leaders speculate that the semiconductor shortage could persist into 2023.

Based on the ongoing disruption and supply chain volatility, various analysts in a recent CNBC article and Bloomberg interview echoed their views, and many are convinced that the coming year will be challenging. Here are some of the key takeaways:

Pat Gelsinger, CEO of Intel Corp., noted in April 2021 that the chip shortage would recover after a couple of years.

DigiTimes Report found that Intel and AMD server ICs and data centers have seen their lead times extend to 45 to 66 weeks.

The world’s third-largest EMS and OEM provider, Flex Ltd., expects the global semiconductor shortage to proceed into 2023.

In May 2021, Global Foundries, the fourth-largest contract semiconductor manufacturer, signed a $1.6 billion, 3-year silicon supply deal with AMD, and in late June, it launched its new $4 billion, 300mm-wafer facility in Singapore. Yet, the company says its production capacity will only increase component production earliest in 2023.

TMSC, one of the leading pure-play foundries in the industry, says it won’t meaningfully increase the component output until 2023. However, it’s optimistic that the company will ramp up the fabrication of automotive micro-controllers by 60% by the end of 2021.

From the industry insights above, it’s evident that despite the many efforts that major players put into resolving the global chip shortage, the bottlenecks will probably persist throughout 2022.

Additionally, some industry observers believe that the move by big tech companies such as Amazon, Microsoft, and Google to design their own chips for cloud and data center business could worsen the chip shortage crisis and other problems facing the semiconductor industry.

article, the authors hint that the entry of Microsoft, Amazon, and Google into the chip design market will be a turning point in the industry. These tech giants have the resources to design superior and cost-effective chips of their own, something most chip designers like Intel have in limited proportions.

Since these tech giants will become independent, each will be looking to create component stockpiles to endure long waits and meet production demands between inventory refreshes. Again, this will further worsen the existing chip shortage.

Possible Solutions

To stay ahead of the game, major industry players such as chip designers and manufacturers and the many affected industries have taken several steps to mitigate the impacts of the chip shortage.

For many chip makers, expanding their production capacity has been an obvious response. Other suppliers in certain regions decided to stockpile and limit exports to better respond to market volatility and political pressures.

Similarly, improving the yields or increasing the number of chips manufactured from a silicon wafer is an area that many manufacturers have invested in to boost chip supply by some given margin.

Here are the other possible solutions that companies have had to adopt:

Embracing flexibility to accommodate older chip technologies that may not be “state of the art” but are still better than nothing.

Leveraging software solutions such as smart compression and compilation to build efficient AI models to help unlock hardware capabilities.

LED Lighting

The latest global chip shortage has led to severe shocks in the semiconductor supply chain, affecting several industries from automobile, consumer electronics, data centers, LED, and renewables.

Industry thought leaders believe that shortages will persist into 2023 despite the current build-up in mitigation measures. And while full recovery will not be witnessed any time soon, some chip makers are optimistic that they will ramp up fabrication to contain the demand among their automotive customers.

That said, staying ahead of the game is an all-time struggle considering this is an issue affecting every industry player, regardless of size or market position. Expanding production capacity, accommodating older chip technologies, and leveraging software solutions to unlock hardware capabilities are some of the promising solutions.

As networking switches and modern servers, indispensable equipment in datacenter applications, use more advanced components than an average consumer’s PC, naturally when it comes to chip manufacturers and suppliers, data centers are given the top priority. However, with the demand for data center machines far outstripping supply, chip shortages may continue to be pervasive across the next few years. Coupled with economic uncertainties caused by the pandemic, it further puts stress on datacenter management.

According to a report from the Dell’Oro Group, robust datacenter switch sales over the past year could foretell a looming shortage. As the mismatch in supply and demand keeps growing, enterprises looking to buy datacenter switches face extended lead times and elevated costs over the course of the next year.

“So supply is decreasing and demand is increasing,” said Sameh Boujelbene, leader of the analyst firm’s campus and data-center research team. “There’s a belief that things will get worse in the second half of the year, but no consensus on when it’ll start getting better.”

Back in March, Broadcom said that more than 90% of its total chip output for 2021 had already been ordered by customers, who are pressuring it for chips to meet booming demand for servers used in cloud data centers and consumer electronics such as 5G phones.

“We intend to meet such demand, and in doing so, we will maintain our disciplined process of carefully reviewing our backlog, identifying real end-user demand, and delivering products accordingly,” CEO Hock Tan said on a conference call with investors and analysts.

Major Implications

Extended Lead Times

Arista Networks, one of the largest data center networking switch vendors and a supplier of switches to cloud providers, foretells that switch-silicon lead times will be extended to as long as 52 weeks.

“The supply chain has never been so constrained in Arista history,” the company’s CEO, Jayshree Ullal, said on an earnings call. “To put this in perspective, we now have to plan for many components with 52-week lead time. COVID has resulted in substrate and wafer shortages and reduced assembly capacity. Our contract manufacturers have experienced significant volatility due to country specific COVID orders. Naturally, we’re working more closely with our strategic suppliers to improve planning and delivery.”

Hock Tan, CEO of Broadcom, also acknowledged on an earnings call that the company had “started extending lead times.” He said, “part of the problem was that customers were now ordering more chips and demanding them faster than usual, hoping to buffer against the supply chain issues.”

Elevated Cost

Vertiv, one of the biggest sellers of datacenter power and cooling equipment, mentioned it had to delay previously planned “footprint optimization programs” due to strained supply. The company’s CEO, Robert Johnson, said on an earnings call, “We have decided to delay some of those programs.”

Supply chain constraints combined with inflation would cause “some incremental unexpected costs over the short term,” he said, “To share the cost with our customers where possible may be part of the solution.”

“Prices are definitely going to be higher for a lot of devices that require a semiconductor,” says David Yoffie, a Harvard Business School professor who spent almost three decades serving on the board of Intel.

Conclusion

There is no telling that how the situation will continue playing out and, most importantly, when supply and demand might get back to normal. Opinions vary on when the shortage will end. The CEO of chipmaker STMicro estimated that the shortage will end by early 2023. Intel CEO Patrick Gelsinger said it could last two more years.

As a high-tech network solutions and services provider, FS has been actively working with our customers to help them plan for, adapt to, and overcome the supply chain challenges, hoping that we can both ride out this chip shortage crisis. At least, we cannot lose hope, as advised by Bill Wyckoff, vice president at technology equipment provider SHI International, “This is not an ‘all is lost’ situation. There are ways and means to keep your equipment procurement and refresh plans on track if you work with the right partners.”

Data Center Infrastructure Basics and Management Solutions

Share

Datacenter infrastructure refers to all the physical components in a data center environment. These physical components play a vital role in the day-to-day operations of a data center. Hence, data center management challenges are an urgent issue that IT departments need to pay attention to. On the one hand, it is to improve the energy efficiency of the data center; on the other hand, it is to know about the operating performance of the data center in real-time ensuring its good working condition and maintaining enterprise development.

Data Center Infrastructure Basics

The standard for data center infrastructure is divided into four tiers, each of which consists of different facilities. They mainly include cabling systems, power facilities, cooling facilities, network infrastructure, storage infrastructure, and computing resources.

There are roughly two types of infrastructure inside a data center: the core components and IT infrastructure. Network infrastructure, storage infrastructure, and computing resources belong to the former, while cooling equipment, power, redundancy, etc. belong to the latter.

Core Components

Network, storage, and computing systems are vital infrastructures for data centers to achieve sharing access to applications and data, providing data centers with shared access to applications and data. Also, they are the core components of data centers.

Network Infrastructure

Datacenter network infrastructure is a combination of network resources, consisting of switches, routers, load balancing, analytics, etc., to facilitate the storage and processing of applications and data. Modern data center networking architectures, through using full-stack networking and security virtualization platforms that support a rich set of data services, can achieve connecting everything from VMs, containers, and bare-metal applications, while enabling centralized management and fine-grained security controls.

Storage Infrastructure

Datacenter storage is a general term for the tools, technologies and processes for designing, implementing, managing and monitoring storage infrastructure and resources in data centers, mainly referring to the equipment and software technologies that implement data and application storage in data center facilities. These include hard drives, tape drives and other forms of internal and external storage and backup management software utilities external storage facilities/solutions.

Computing Resources

A data center meter is a memory and processing power to run applications, usually provided by high-end servers. In the edge computing model, the processing and memory used to run applications on servers may be virtualized, physical, distributed among containers or distributed among remote nodes.

IT Infrastructure

As data centers become critical to enterprise IT operations, it is equally important to keep them running efficiently. When designing data center infrastructure, it is necessary to evaluate its physical environment, including cabling system, power system, cooling system to ensure the security of the physical environment of the data center.

Cabling Systems

The integrated cabling is an important part of data center cable management, supporting the connection, intercommunication and operation of the entire data center network. The system is usually composed of copper cables, optical cables, connectors and wiring equipment. The application of the data center integrated wiring system has the characteristics of high density, high performance, high reliability, fast installation, modularization, future-oriented, and easy application.

Power Systems

Datacenter digital infrastructure requires electricity to operate. Even an interruption of a fraction of a second will result in a significant impact. Hence, power infrastructure is one of the most critical components of a data center. The data center power chain starts at the substation and ends up through building transformers, switches, uninterruptible power supplies, power distribution units, and remote power panels to racks and servers.

Cooling Systems

Data center servers generate a lot of heat while running. Based on this characteristic, cooling is critical to data center operations, aiming to keep systems online. The amount of power each rack can keep cool by itself places a limit on the amount of power a data center can consume. Generally, each rack can allow the data center to operate at an average 5-10 kW cooling density, but some may be higher.

Data Center Infrastructure Management Solutions

Due to the complexity of IT equipment in a data center, the availability, reliability, and maintenance of its components require more attention. Efficient data center operations can be achieved through balanced investments in facilities and accommodating equipment.

Energy Usage Monitoring Equipment

Traditional data centers lack the energy usage monitoring instruments and sensors required to comply with ASHRAE standards and collect measurement data for use in calculating data center PUE. It results in a poor monitoring environment for the power system of the data center. One measure is to install energy monitoring components and systems on power systems to measure data center energy efficiency. Enterprise teams can implement effective strategies by the measure to balance overall energy usage efficiency and effectively monitor the energy usage of all other nodes.

Cooling Facilities Optimization

Independent computer room air conditioning units used in traditional data centers often have separate controls and set points, resulting in excessive operation due to temperature and humidity adjustments. It’s a good way for helping servers to achieve cooling by creating hot-aisle/cold-aisle layouts to maximize the flow of cold air to the equipment intakes and the hot exhaust air from the equipment racks. The creation of hot or cold aisles can eliminate the mixing of hot and cold air by adding partitions or ceilings.

CRAC Efficiency Improvement

Packaged DX air conditioners likely compose the most common type of cooling equipment for smaller data centers. These units are often described as CRAC units. There are, however, there are several ways to improve the energy efficiency of the cooling system employing DX units. Indoor CRAC units are available with a few different heat rejection options.

  • – As with rooftop units, adding evaporative spray can improve the efficiency of air-cooled CRAC units.
  • – A pre-cooling water coil can be added to the CRAC unit upstream of the evaporator coil. When ambient conditions allow the condenser water to be cooled to the extent that it provides direct cooling benefits to the air entering the CRAC unit, the condenser water is diverted to the pre-cooling coil. This will reduce or sometimes eliminate the need for compressor-based cooling for the CRAC unit.

DCIM

Data center infrastructure management is the combination of IT and operations to manage and optimize the performance of data center infrastructure within an organization. DCIM tools help data center operators monitor, measure, and manage the utilization and energy consumption of data center-related equipment and facility infrastructure components, effectively improving the relationship between data center buildings and their systems.

DCIM enables bridging of information across organizational domains such as data center operations, facilities, and IT to maximize data center utilization. Data center operators create flexible and efficient operations by visualizing real-time temperature and humidity status, equipment status, power consumption, and air conditioning workloads in server rooms.

Preventive Maintenance

In addition to the above management and operation solutions for infrastructure, unplanned maintenance is also an aspect to consider. Unplanned maintenance typically costs 3-9 times more than planned maintenance, primarily due to overtime labor costs, collateral damage, emergency parts, and service calls. IT teams can create a recurring schedule to perform preventive maintenance on the data center. Regularly checking the infrastructure status and repairing and upgrading the required components promptly can keep the internal infrastructure running efficiently, as well as extend the lifespan and overall efficiency of the data center infrastructure.

What Are Data Center Tiers?

Understanding Data Center Redundancy

Share

Maximizing the uptime should be the top priority for every data center, be they small or hyperscale. To keep your data center constantly running, a plan for redundancy systems is a must.

What Is Data Center Redundancy?

Data center redundancy refers to a system design where critical components such as UPS units, cooling systems and backup generators are duplicated so that data center operations can continue even if a component fails. For example, a redundant UPS system starts working when a power outage happens. In the event of downtime due to hazardous weather, power outages, or component failures, data center backup components play their role to keep the whole system running.

Why Is Data Center Redundancy Important?

It is imperative for businesses to increase uptime and recover more quickly from downtime, whether unexpected or planned. Downtime hurts business. It can have serious and direct impact on brand images, business operations, and customer experience, resulting in devastating financial losses, missed business opportunities and a tarnished reputation. Even for small businesses, unscheduled downtime can still cost hundreds of dollars per minute.

Redundancy configuration in data centers helps cut the risk of downtime, thus reducing losses caused by undesired impacts. A well-planned redundancy design means shorter potential downtime in the long run. Moreover, redundant components also ensure that data is safe and secure as data center operations keep working and never fail.

Redundancy is also a crucial factor in gauging data center reliability, performance and availability. The Uptime Institute offers a tier classification system that certifies data centers according to four distinct tiers—Tier 1, Tier 2, Tier 3 and Tier 4. Each tier has strict and specific requirements around data center redundancy level.

Different Levels of Redundancy

There is no one-size-fits-all redundancy design. Lower levels of redundancy mean increased potential downtime in the long run. While more redundancy will result in less downtime but increased costs of maintaining the redundant components. however, if your business model requires as little downtime as possible, this is often justifiable in terms of profit and overall net growth. To choose the right configuration for your business, it is important to recognize the capabilities and risks of different redundancy models, including N, N+1, N+X, 2N, 2N+1, and 3N/2.

N Model

N equals the amount of capacity required to power, backup, or cool a facility at full IT load. It can represent the units that you want to duplicate such as a generator, UPS, or cooling unit. For example, if a data center requires three UPS units to operate at full capacity, N would equal three.

An architecture of N means the facility is designed only to keep a data center running at full capacity. Simply put, N is the same as zero redundancy. If the data center facility is at full load and there is a hardware failure, scheduled maintenance, or an unexpected outage, mission-critical applications would suffer. With an N design, any interruption would leave your business unable to access your data until the issue is resolved.

N+1 or N+X Model

An N+1 redundancy model provides a minimal level of resiliency by adding a single component—a UPS, HVAC system or generator—to the N architecture to support a failure and maintain a full workload. When one system is offline, the extra component takes over the load. Going back to the previous example, if N equals three UPS units, N+1 provides four. Likewise, an N+2 redundancy design provides two extra components. In our example, N+1 provides five UPS units instead of four. So N+X provides N+X extra components to reduce risks in the event of multiple simultaneous failures.

2N Model

2N redundancy creates a mirror image of the original UPS, cooling system or generators to provide full fault tolerance. It means if three UPS units are necessary to support full capacity, this redundancy model would include an additional set of three UPS units, for a total of six systems. This design also utilizes two independent distribution systems.

With a 2N model, data center operators can take down an entire set of components for maintenance without affecting normal operations. Moreover, in the event of unscheduled multiple component failures, the additional set takes over to maintain full capacity. The resiliency of this model greatly cuts the risks of downtime.

2N+1 Model

If 2N means full fault tolerance, 2N+1 delivers the fully fault-tolerant 2N model plus an extra component for extra protection. Not only can this model withstand multiple component failures, even in a worst-case scenario when the entire primary system is offline, it can still sustain N+1 redundancy. For its high level of reliability, this redundancy model is generally used by businesses that cannot tolerate even minor service disruptions.

N+1 2N+1 redundancy

3N/2 Model

The three-to-make-two or 3N/2 redundant model refers to a redundancy methodology where additional capacity is based on the load of the system. If we consider a 3N/2 scenario, three power delivery systems will power two servers, which means each power delivery system utilizes 67% of the available capacity. Likewise, in a 4N/3, there will be four power delivery systems powering three workloads (three servers). The 3N/2 could be upgraded to 4N/3, but only in theory. This is because such an elaborate model has so many components that it would be very difficult to manage and balance loads to maintain redundancy.

3N/2 redundancy

What’s the Right One for You?

Choosing a redundant model that meets your business needs can be challenging. Finding the right balance between reliability and cost is the key. For businesses that require as little downtime as possible, higher levels of redundancy are justifiable in terms of profit and overall net growth. For those that do not, lower levels of redundancy are acceptable. They are cheaper and more energy-efficient than the other more sophisticated redundancy designs.

In a word, there’s no right or wrong redundancy model because it depends on a range of factors like your business goals, budget, and IT environment. Consult your data center provider or discuss with your IT team to figure out the best option for you.

5 Factors to Consider for Data Center Environmental Monitoring

What Are Data Center Environmental Standards

Data center environmental monitoring is vital for device operations. The data center architecture is divided into four layers where the equipment placed inside also affects the design of data center environmental standards.

  • Tier I defines data center standards for facilities with minimal redundancy.
  • Tier II provides redundant critical power and cooling components.
  • Tier III adds redundant transmission paths for power and cooling to redundant critical components.
  • Tier IV infrastructure is built on Tier Ⅲ and adds the concept of fault tolerance to infrastructure topology.

Enterprises must comply with fairly stringent environmental standards to ensure these facilities remain functional.

Evolution of Data Center Environmental Standards

As early as the 1970s and 1980s, data center environmental monitoring revolved around power facilities. For example, whether the environment where the power supply was located has proper isolation, whether the main power supply affected the operation of the overall equipment, but the cooling problem was rarely monitored. Some enterprises have explored cooling technologies to facilitate cooling in data centers, such as liquid cooling. Typically, enterprises used loud fans to control airflow. In some countries, the cost of electricity was high, so there was a greater emphasis on being able to supply enough electricity for a given system configuration.

In the 1990s, the power density of the rack became a considered issue of enterprise data center environmental standards. In the past, a simple power factor calculation could yield the required cooling value for a data center, but accurate cooling values could not be provided by the increasing rack densities. At this point, enterprises had to re-plan the airflow patterns of data center racks and equipment. This required IT managers to know more statistics when designing a data center, such as pressure drop, air velocity, and flow resistance.

By the early 20th century, power densities were still increasing, and thermal modeling was seen as a potential answer to optimizing the cooling of data center environments. The lack of necessary data implied that temperature data typically was collected after data center construction and then IT managers needed to make adjustments based on that information. Enterprises should choose the correct thermal model of equipment when building a data center to enhance data center environmental monitoring. Here are several environmental control methods when building a data center.

5 Factors in Data Center Environmental Controls

For ensuring the reliable operation of IT equipment within a rack, the primary concerns for monitoring and controlling data center environmental conditions are temperature, humidity, static electricity, physical and human safety. Moreover, data center environmental impact resulted from these factors not only on the ecological environment but also on data center security, energy efficiency, and the enterprise social image.

Temperature Control

Thermal control is always a challenging issue for data centers, as servers emit heat when they are running. If they are paralyzed by overheating, it will cripple data center operations. Temperature control can check if equipment is operating within the recommended temperature range. A temperature sensor is an effective method to solve temperature control. Placing them in strategic locations and reading the overall temperature allows IT managers to conduct temperature control promptly.

Humidity Control

Humidity control is closely related to temperature levels. High humidity can corrode hardware. Low humidity levels can cause electrostatic arcing problems. For this reason, cooling and ventilation systems need to detect and control the relative humidity in the room air. ASHRAE recommends operation within a dew point range of 41.9 to 59 degrees Fahrenheit with a maximum relative humidity of 60%. Datacenter designers need to invest in systems that can detect humidity and water near equipment to better monitor cooling fans and measure the presence of airflow during routine management. Of course, it is also possible to use a set of computer room air conditioner(CRAC) units on larger facilities to create consistent airflow that flows throughout the room. These CRAC systems typically work by drawing in and cooling heat, then expelling it as cool air through vents and air intakes leading to the server.

Electricity Monitoring

Static electricity is also one of the threats in the data center environment, it is an invisible nuisance. Some newer IT components can be damaged or completely fried by less than 25 volts of discharge. If this problem isn’t addressed, it might result in frequent disconnections, system crashes, and even data corruption. Unexpected bursts of energy in the form of electrostatic discharges may be the greatest threat to the performance of the average data center. To prevent such incidents, businesses must install energy monitors that are strategically located to detect the buildup of static electricity.

Fire Suppression

A comprehensive fire suppression system is a must-have feature in data center environmental standards. If an entire data center is to be protected from disaster, data center designers need to take security measures from fire and fire suppression systems to physical and virtual systems. Fire suppression systems are subject to regular testing and active monitoring of the data center to ensure that they will indeed do their job in the clutch.

Security Systems

Data security of data center environmental standards is also very important. IT departments must institute a limit that keeps intruders away from buildings as well as server rooms and the racks they are in. Setting up a complete range of physical security is a desirable method—from IP surveillance systems to advanced sensors. If unauthorized personnel is detected entering a building or server rack, it will alert data center managers.

Summary

The purpose of data center environmental monitoring is to provide a better operating environment for facilities and avoid some unplanned cases that affect the business of enterprises. For the above data center environmental controls, it is beneficial for enterprises to maintain data center security when designing data centers, which is conducive to data center management. Also, it properly controls the data center environmental impact on ecology and energy efficiency.
