A customer has a SAN fabric consisting of several MDS9509s for host to disk array connectivity.
They have purchased a Fibre Channel tape library and want to implement LANfree backups. You have proposed making a tape VSAN on the existing MDS infrastructure and have recommended that they use QoS so that tape I/O does not use ISL bandwidth at the expense of disk I/O.
Which license is needed on the MDS directors?

A.
Enterprise package

B.
Fabric Manager Server

C.
Storage Services Enabler package

D.
Tape Write Acceleration package
