FacebookTwitterGoogle+LinkedInRedditTumblrShare

With the fast development of today’s networking field, many people tend to build 10G network in small and midsize business for their growing network needs. Then, why they choose 10G network? How to build an affordable one? If you want to build such a network, what things you should know? Don’t worry. Let’s find all the answers in the following text.

Necessity of 10G network

Actually, the necessity of 10G network is quite simple to understand. As time goes on, there will be more traffic and applications running on your existing networks and they will keep growing. At that time, the common used Gigabit network will no longer satisfy the urgent needs for higher networking speeds and larger network construction.

How to Build An Affordable 10G Network?

To build a 10G network, there are several indispensable components you need, such as 10GbE switch (10G core switch and access switch with 10G uplinks), 10G SFP+ modules, fiber cables, severs and storage devices, etc.

10G network layout

To build an affordable 10G network for small and midsize business (SMB), let’s take fiber cabling solution as an example.

Fiber Cabling Solution for 10G Network

Under such circumstance, the server or storage has 10G SFP+ port. And it is suitable for applications matching with a 10G fiber switch as the core switch. You can connect all the devices with the steps below:

Step 1: Connect Server Or Storage to A Core Switch

For connection between server (or storage) and a core switch, you can insert a 10G transceiver module connecting with one end of a LC cable into the server or storage, and then connect the other end of the LC cable with the core switch.

Here, the transceiver we use is 10G SFP+ module provided by FS.COM. It can reach a maximum cable distance of 300m over OM3 multimode fiber (MMF).

The LC cable we use is LC UPC to LC UPC duplex OM3 MMF, which has less attenuation when bent or twisted compared with traditional optical fiber cables and will make the installation and maintenance of the fiber optic cables more efficient.

What’s more, the core switch we use is FS S5850-48S2Q4C. This network switch is a 48-port 10Gb SFP+ L2/L3 carrier grade switch with 6 hybrid 40G/100G uplink ports. It is a high performance top of rack (ToR) or leaf switch to meet the next generation metro, data center and enterprise network requirements.

Step 2: Connect the Core Switch With An Access Switch

Next, you need to connect the core switch with an access switch. Just like step 1, insert a 10G transceiver module connecting with one end of a LC cable into the core switch, and then connect the other end of the LC cable with the access switch.

Here, we use FS Gigabit Ethernet switch with 10G SFP+ uplink as the access switch. This is a fanless switch, which is suitable for quilt requirement in SMB network. In addition, it has 24 10/100/1000BASE-T ports and 4 10Gb SFP+ ports for uplinks.

And the LC cable and 10G transceiver we use are the same as the products used in step 1.

Step 3: Connect Your Access Switch to Computers

After the previous two steps, you can use Cat5 or Cat5e cable (here we use Cat5e) to connect your access switch with computers or other devices you need to use. Just remember that you have to connect the 10/100/1000BASE-T ports rather than the 10Gb SFP+ ports.

Network OS Systems for Bare Metal Switch

As you may know that a network switch with no network operating system (NOS) is referred to as a bare metal switch. Unlike a white box switch with vendor’s own or 3rd party already loaded NOS, a bare metal switch allows you to load a network OS according to your own will. After installing the NOS, these two types of switches are normally regarded as the same. Then, how to choose network OS systems for bare metal switches? Listed below are three popular choices, namely Cumulus Linux, IP Infusion OcNOS™ and Pica8 PICOS.

Option 1: Network OS Cumulus Networks Cumulus Linux

Cumulus Linux is a powerful open network OS designed by Cumulus Networks to help build and operate large data center networks. Therefore, the Cumulus Linux is a perfect match for a data center switch which operates in bigger networks such as enterprise, data center and metro Ethernet scenarios. It is a true Linux distribution with a hardware abstraction layer that runs on a variety of commodity hardware. Cumulus Linux uses automated tools to manage the network infrastructure and hopes to automate the configuration of network switches with these existing tools.

Cumulus Linux network OS

Additionally, Cumulus Linux offers economical scalability and choice flexibility to run multiple network paths without the need for multiple switches. The main features of Cumulus Linux lie in the following aspects:

  • Economical Scalability: Customers can get increased operational efficiency with commodity hardware and a standardized Linux stack.
  • Built for the Automation Age: This Debian-based Linux distribution offers a completely open architecture and is designed for easy automation.
