Leveraging a Flex System environment: FCoE end-to-end

Figure 9 shows an example of how a client can use the G8264CS for convergence in a Flex System environment to

connect directly into their storage using FCoE. This approach can help clients significantly reduce costs inside the

chassis by removing the need for FC SAN switches between the G8264CS and the storage. In the chassis, you

simply have a single adapter in the compute node using CNA functionality, with a 10Gb Ethernet module, such as

the SI4093/EN4093/EN4093R, in the chassis (no FC adapter or switches necessary). The client can then use the

G8264CS at the top of the rack or elsewhere in the data center and then connect directly into the storage device.

Note: FLOGI is used to obtain a routable FCID for use in the FC frame exchange between the G8264CS and the

Storwize V7000. The switch provides the FCID during a FLOGI exchange.
