Using TDVV volumes for replciation

[mut123]

Are there any performance impacts of using TDVV volumes for Sync and Async replication ?

Hello @mut123,

The is no performance impact if you are replicating a TDVV via sync or async replication.
But note that replication from an all-SSD TDVV to a non-SSD TDVV is not supported. You have to replicate a TDVV to an SSD CPG on the target. Basically TDVVs are supported only on SSDs. That rule remains same at the replication target as well.

So, here no rehydration of data involved, no performance impact, TDVV replicates as TDVV, remains as TDVV at the target regardless of sync or async type of replication.

Thanks @sbhat09  for confirming. Is there any document/manual that mentions no perf impacts if TDVV is used for sync/async replication. If so, can you share the link so that I can share it with my team.
