Fcip Tape Acceleration - Cisco AJ732A - MDS 9134 Fabric Switch Release Note

FC AND FCIP WRITE ACCELERATION FEATURE MUST NOT BE
ENABLED WHEN IMPLEMENTING CONTINUOUS ACCESS
ENTERPRISE VIRTUAL ARRAY
Continuous Access Enterprise Virtual Array includes an FC/FCIP write acceleration feature. For
this reason, Cisco's FC and FCIP write acceleration must not be enabled in a Continuous Access
EVA environment. By default Cisco SAN-OS write acceleration is disabled.

FCIP TAPE ACCELERATION

support shared tape library options. If this issue is encountered, disable the feature.
Note: FCIP Tape Read Acceleration can only be enabled when both ends of the FCIP tunnel are
running SAN-OS 3.0(1) or newer
