short_description: Manage protection groups on Pure Storage FlashArrays
description:
- Create, delete or modify protection groups on Pure Storage FlashArrays.
- If a protection group exists and you try to add non-valid types, eg. a host
to a volume protection group the module will ignore the invalid types.
- Protection Groups on Offload targets are supported.

target:
description:
- List of remote arrays or offload target for replication protection group
to connect to.
- Note that all replicated protection groups are asynchronous.
- Target arrays or offload targets must already be connected to the source array.
- Maximum number of targets per Protection Group is 4, assuming your
configuration supports this.
