Re: B2B and write acc

B2B is a flow control mechanism for a single link, while WA is SCSI ack spoofing to speed up the write command sequence. B2B is documented in the FC standards while WA is Cisco specific and only available via the IP modules for FCIP-WA or via the SSM/SSN modules for pure FC-WA.
