Release Notes HP C-series FC Switches for NX-OS_5.2(8a)(5697-2659, July 2013)

22 MDS 9000 Series Multilayer Director & Multilayer Fabric Switches Release Notes
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.
