We brought up this question to the implementation engineer. We were comparing use cases where a customer is using RecoverPoint, then goes to PowerMax. In our previous setup with XtremIO, we were using RecpverPoint and keeping snapshots for 30 days, every few seconds. With PowerMax, I requested this for every 15 minutes, keeping it for a week. The engineer's answer was, "There will be too many snapshots. It might slow down the system." This is specifically for the use cases where there is RecoverPoint. While PowerMax works with RecoverPoint, and you can use it, there should be some way where you can have even more snapshots and not to worry about performance and system cache.
