Nowadays the adoption of 100Gps has gained momentum in most data centers and some hyperscale data centers are moving towards higher speed 400Gbps, which paves the way for the development of 400G data center switches.ĭata center switches also have varying port types and numbers, based on which specific cabling and transceivers are selected, so you should know what you need now and make a reasonable estimate of what you'll need in the future.
Fiber connectivity varies from 10 Gbps, 25 Gbps to 40Gbps, and even more. It's advisable to make up your mind early enough on the connectivity that you will be using. The size of fiber connections that you'll need should also be well considered. A smaller switch is economical, but you'll have to install it in a top-of-rack manner to prevent bottlenecks. A large switch requires more resources to install and will serve your current and future needs. Choosing the right size for your business will depend on the current and future data flow. Size, Number of Ports, and Data Rateĭata center switches come in varying sizes. And some data center switches support Ansible/OpenFlow configuration and automation tools for easy management.
You should ask yourself a few questions to decide what functions are needed? Are you going to use enterprise level applications? Are you considering redundancy? Do you have a virtualized infrastructure? For example, a reliable data center switch should have the capability to automate as well as support newer protocols such as EVPN and VXLAN. Based on their use cases and applications, different switches have unique characteristics. FunctionsĪll switches have the same basic functionality, such as using standards-based protocols or maintaining a MAC address-to-port table. There are many factors to consider and here lists some of the most important ones in several aspects. Things To Consider When Buying Data Center SwitchesĬhoosing a data center switch can be a difficult task, no matter if you are deploying a new data center or deciding to upgrade the existing network infrastructure.
