Protection Groups and Storage vMotion

[TheVMinator]

I'm using array based replication and need to balance some datastores.   As I move virtual machines to different datastores, how do I minimize the work to keep the VMs in their current protection groups?  Do I need to create one protection group for every group of datastores that a VM might ever live on, so that storage vmotion operations do not move a Vm out of its protection group?

‌That's what I would do. Name the datastores so it's obvious which group they belong to - keep consistency groups and protection groups aligned and try to keep it simple...

SRM 6 also supports Storage DRS / data store clusters so you can let SDRS automatically move VMs in order to manage capacity.

Using Site Recovery Manager with Array-Based Replication on Sites with Storage DRS or Storage vMotio...

It's worth considering what will happen to the replication as well. Moving a VM to a different LUN will probably cause your array to re-replicate all of it's data to the recovery site which is a costly operation in many cases.
