Configuring FICON Tape Acceleration
FICON tape acceleration has the following configuration considerations:
•
In addition to the normal FICON configuration, FICON tape acceleration must be enabled on both
ends of the FCIP interface. If only one end has FICON tape acceleration enabled, acceleration does
not occur.
•
FICON tape acceleration is enabled on a per VSAN basis.
•
FICON tape acceleration cannot function if multiple ISLs are present in the same VSAN
(PortChannels or FSPF load balanced).
