Figure 20. Embedded Fibre Channel Switch Module block diagram
The Embedded Fibre Channel Switch Module is configured with three components: A Brocade Fibre
Channel switch, Fibre Channel HBAs, and network adapters. Directly connecting the HBAs to the FC
switch in this manner, rather than installing them as PCI cards in the blades eliminates the 16 fiber
cables that would be necessary to make these connections in other systems, as illustrated in Figure 21.
Another benefit is reduced latency on the data path. This dramatically reduces complexity,
administration, and points of failure in FC environments. It also reduces the effort to install and/or
reconfigure the storage infrastructure.
