Chapter 12. Cisco FCIP implementation 367
When FCIP write acceleration is enabled, WAN throughput is maximized by
minimizing the impact of WAN latency for the command to transfer ready
acknowledgement.
The write acceleration feature is disabled by default and must be enabled on both
sides of the FCIP link. If it is only enabled on one side of the FCIP tunnel, the
tunnel will not initialize.
In some cases, data sent by the host is queued on the target before the target
issues a Transfer Ready. This way, the actual write operation might be done in a
less time than the write operation without the write acceleration feature being
enabled.
