Figure 91 FCIP impact on existing iSCSI configurations – single fabric per blade
Figure 92 FCIP impact on existing iSCSI configurations — dual fabrics per blade
In the dual FC fabric case, the impact is higher because after adding an FCIP Route there is only
one remaining FC port available for iSCSI. Therefore, only the targets from one fabric or the other
will be available to iSCSI initiators connected to that MPX200 blade; access to targets on the other
fabric are through another MPX200 blade.
FCIP and iSCSI performance
In most use cases, mixing iSCSI and FCIP on the same blade provides adequate performance.
However, high availability/performance goals may dictate a dedicated MPX200 for each function
or protocol. For example, if your performance needs are for more that 8 Gb/s of FC access for
iSCSI alone, configuring FCIP on the same blade would limit FC access to only 8 Gb/s and would
not meet the performance requirements for that situation.
