Leveraging a Flex System or PureSystems environment: FCoE end-to-end
Figure 10 shows an example of how a client can use the G8264CS for convergence in a Flex System or
PureSystem 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.
