The IBM Flex System™ FC5022 16Gb SAN Scalable Switch is a Gen 5 Fibre Channel (FC) high-density, 48-port switch that operates at 16 and 8 Gbps FC speeds and is used in the IBM Flex System chassis. The switch provides 28 internal ports to compute nodes by way of the Flex midplane and 20 external SFP+ ports, as shown in Figure 1. The FC5022 SAN switch module delivers a scalable embedded option for IBM Flex System users connecting to 8 or 16 Gbps FC storage, deploying a new storage area network (SAN) or connecting to an existing SAN in their enterprise. The switch offers end-to-end 16 Gb with backwards compatibility to 8 Gb and 4 Gb to the SAN connectivity. Monitoring and management are simplified using end-to-end Brocade tools, such as Web Tools and the Brocade Network Advisor (BNA).
