Calculation of cache memory required for CoW Snapshot.

I am looking into a solution to implement CoW Snapshots into an existing environment.

Current configuration has two VSPs (one each in a DC) with TrueCopy Synchronous replicaiton between two sites.

The idea of implementation is, (VSP-Local) TC > (VSP-Remote) TC > SI > CoW.

My concern is the cache memory utilization by CoW Snapshots.

Existing cache memory allocation has been set to three CLPRs (CLPR1, CLPR2, CLPR3).

I would like to know, if I can make use of the available existing cache memory for CoW or there should be a dedicated set of memory for it.

How is the calculation of memory which will be required by CoW Snapshots?


Please advise in any way possible you can.
