If you want to keep your critical business running, you need to build your system in a redundant manner. The redundancy scheme is actually a server type, and the scheme is various. It can be a single switch component redundancy, and a dual fiber switching network redundancy configuration scheme can also be considered, but the cost is very high. However, since this dual-network topology ensures redundancy, a cheaper single-supply switching device can be used. Even if one switch fails, the link switching software on the host and the storage array automatically switches the communication to redundancy. On the device until the faulty device is replaced. If regular downtime maintenance does not affect the enterprise's application, then a switch with only hot-swappable redundant power supplies and fans can be used to significantly reduce costs. It also ensures that any single point of failure of the power supply or fan does not affect the operation of the network.
In summary, there are many areas to consider before choosing which switch to use to build a SAN fabric switch. As with other equipment procurement plans, you need to identify key future requirements before comparing switches, and prioritize these requirements.
The above are just some of the things to pay attention to when purchasing a fiber-optic switch. In fact, the technology of the fiber-optic switch is very complicated. The types of protocols and interfaces supported are also increasing. The performance is constantly enhanced. There are still many aspects to be noted, but it is limited to the length. In this article, we can only play a role in inspiring everyone. I hope that you have certain reference significance when purchasing fiber-optic switches.
