Our current configuration is a pair of USP-Vs approximately 50km apart in a synchronous replication state.
In addition to being synchronously replicated these same LDEVs are also in a consistent FlashCopy incremental state.
The portion of the workload that I am particularly interested in moving to VSPs is made up of just short of 500 x Mod 54 Volumes plus obviously the same number of TrueCopy sync volumes and FlashCopy volumes.
This a very response time critical DB2 workload so we would like to be very comfortable before we commence moving to the VSPs.
Does anyone have a workload anything like this running on a VSP?
If you do, have you observed any host response time issues during FlashCopy processing?
Have you observed any stress on the MPs during FlashCopy internal COPY operations?
I am just a little concerned that the shared MP setup in the VSPs may result in host response degradation during the COPY phase of our daily FCIncremental processing-
Even if your workload is smaller, but similarly configured, I would be interested in your experiences.
