Companies looking to implement Fibre Channel SANs need to purchase the right switch from the right vendor. In this tutorial, you will learn how to decide on the right Fibre Channel SAN switch, and how to maintain switch performance. Table of contents:
>> How to select a Fibre Channel switch for your SAN Selecting a Fibre Channel switch for your SAN For any organization building a SAN, the switch is a key decision point . The switch inspects a data packet, determines where it came from and where it's going, then forwards the packet to the intended storage destination in the data center. Fibre Channel SAN switches serve the same general purpose as any other network switches: automatically connecting senders and receivers. But a Fibre Channel switch was specifically designed to handle heavy transaction loads over high-performance Fibre Channel networks. The two main types of Fibre Channel SAN switches are the high port-count, modular director switch and the smaller fixed-port or semi-modular switch. As a company expands its SAN environment, it can enable additional ports by using a software license key to unlock them. Read more about how to select a Fibre Channel switch for your SAN. Best practices for Fibre Channel switching environments Companies looking to implement a Fibre Channel SAN should know that it's a bad idea to mix and match brands. Fibre Channel switches have to communicate and cooperate with each other to manage the overall fabric. The best way to make sure that happens is to choose a switch from top vendors like Brocade Communications Systems, Cisco Systems or QLogic. "There's a standard for this communication [between the switches], but the standard is kind of a weak, least common denominator of the functions required to build a SAN," says Gartner analyst Robert Passmore. "All of the switch vendors have a much more robust overall set of management functions that are proprietary to [each of them]." There are a few best practices common to all Fibre Channel switching environments, including:
