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
SAN-OS FCIP Tape Acceleration (Write & Read) is disabled by default. Enabling FCIP Tape
Acceleration may cause a tape library to go offline with certain tape backup applications that
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
