Network management experience: Considerations for vswitch Speed upgrade

Considering the current high price of multi-port switches, you can consider smart hubs during upgrade. At present, the difference between the functions and prices of switches and smart hubs has become increasingly vague. Smart hubs improve the disadvantages of General hubs and increase the capability of bridging, you can filter out frames that do not belong to your network segment (similar to a bridge), increase the bandwidth of the network segment, and have the network management capability and automatic detection port, making network maintenance more convenient. When upgrading a hub, you must not only focus on the speed, but also the expansion capability and intelligent management are two important indicators of the hub. Currently, the number of low-price hubs is mostly 8. During expansion, the hubs must support stacking or cascade. These are different methods to solve the problem of insufficient ports of a single hub. Stack is supported by most hubs, but the more layers of stack, the smaller the bandwidth that each user can actually enjoy, and it may cause instability. Comparatively speaking, the cascade method is more advanced. As for the expansion mode of the hub to be upgraded, you should determine the network scale based on the future development trend.

In addition, do not upgrade the hub to a vswitch in the subordinate network of the hub. If the hub is placed at the first level to connect to the server, and the switch is placed at the next level to connect to the workstation, data exchange is still conducted through the hub, and the performance advantages of the switch are not shown. The rationality of the network structure should be fully taken into account during networking, and devices with better performance should be placed at the highest level throughout the network.
