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 NX-OS write acceleration is disabled.

FCIP TAPE ACCELERATION

NX-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.
