Comparison Between 10Gb Switch Under $550

Industrial Ethernet has fast become the network of choice for the interconnection of data center devices, due to its incredible speed, bandwidth and flexibility. The market for network switch is booming as vendors compete to develop items with advanced features and functions. This, however, makes the simple choice of an Ethernet switch overly complex. 10Gb switch is often used as access or leaf switch (depending on your network architecture) in data centers, the importance of which cannot be underestimate. This article will compare some cost-effective 10 Gigabit switches on the market, each of them costs less than $550.

Options of 10Gb Ethernet Switches Under $550

How to Make the Final Decision?

Besides the cost, there are still a variety of factors to weigh when choosing a 10 Gigabit switch, such as: port configuration, switching capacity, power consumption and switch class. To make it simple, we use the chart below to further illustrate it.

Switch Price Switching Capacity Power Consumption 10/100/1000 Ethernet ports Gigabit SFP SFP+ ports Layer Supported
MikroTik CRS226-24G-2S+IN $289.00 88 Gbps 21W 24 / 2 Layer 3

FS S3800-24T4S $399.00 128Gbps ≤40W / 20 4 Layer 2+

We can conclude from the chart that, apart from the price. The port configuration and speed also matters when purchasing a switch. This two factors determine the switching capacity. So you have to consider the amount of traffic to run through the 10Gb switch and select one that can accommodate all the dataflow. Power consumption is also a very important aspect as it defines the operating cost in the long run. Think about tens of thousands of network switch in a middle sized data center, a power efficiency switch can save you a great amount of money.

Conclusion

10G switches is the most effective solution for labs or small deployments. This article compares only a fraction of the important parameters of these switches. Once you have gone through all this factors, choice can thus be make based on your specific condition. Are there any other factors your organization considers when preparing to buy a switch? What do you think are the most important factors? Post your comments below.

Cost Comparison of 10G Leaf Switch and 40G Spine Switch

The growth of network users and the virtualized and automated trend in network have called for a great change in the macro network infrastructure. The “old” three-tier network architecture, namely core, aggregation and access, is quickly proved to be inefficient in modern complicated network environment. So what’s next to replace the outdated frame? After my research, the best I currently find is the flatter leaf-spine network architecture, which surpasses the traditional one with improved switch capacity and much lower latency. This blog will give the cost comparison of 10G leaf switch and 40G spine switch

three-tier network is outdated

In order to help buying a suitable switch when scaling the efficient leaf-spine architecture, I will compare some different brands’ 10G leaf switch (48*10G SFP+ and 6*40G QSFP+) and 40G spine switch (32*40G QSFP+) in this post. It should be noted that each switch price shown below is based on my own research, and I cannot promise that you can get one at the same price, since there are cases of discount, charged shipping, or tax. But you can take it as a reference. And welcome to add new information or to correct mistakes.

10G Leaf Switch (48*10G SFP+ and 6*40G QSFP+), switch capacity being 1.44Tbps.

These open networking leaf and spine switches are almost all adopting Broadcom Trident 2 chip and the Intel 64 processor, the major difference between them lies in the software. Some big brand switches deploy their own network operating system while some support licensed Cumulus Linux OS.

FS provides not only high performance 10G leaf switch (S9000-48S6Q, 48*10G SFP+ and 6*40G QSFP+) and 40G spine switch (S9000-32Q, 32*40G QSFP+) that have excellent Broadcom Trident 2 switching chip and licensed Cumulus Linux OS, and customers also enjoy the easiest addressing of both hardware and software problems. When you buy open networking switch at FS, you can also get certified optics and cables, and professional software support effortlessly and at low cost.

The base prices listed above do not include accessories like optics and fiber optic cables, or the software and hardware support cost. And only a few vendors I know can provide certified optics and cables, and expert software and hardware support at the same time. One-stop experience could only be found at vendors like Cumulus Networks (Cumulus Express service) and FS (Fiberstore). As you know that building a high performance networking is never only about switch, it would be better if simple and all-in-one approach could be provided in switch installation.
