SRDF/A with FCIP

I am implementing pair of PMAX 2000 with brocade FCIP.  The FCIP router itself also support hardware compression.  My thought is it might be make sense to let PMAX to handle the SRDF compression rather than FCIP router since PMAX is also having the compression modules and it is four directors setup so I have four compression modules vs two FCIP switches.

The other feature I am not too sure whether will benefit SRDF/A is fast write.
