HP StorageWorks C-Series Fabric Switches for SAN-OS 3.3(4) and FabricWare 2.1(3) Release Notes (AA-RWEHU-TE, September 2009)

13 MDS Multilayer Director & Multilayer Fabric Switches Release Notes
FCIP Write Acceleration Feature Must Not Be Enabled When
Implementing Continuous Access Enterprise Virtual Array
Continuous Access Enterprise Virtual Array includes an FCIP write acceleration feature. For this
reason, Cisco’s 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
