EMC RecoverPoint : Automated Protection Window Summary
One thing that is often overlooked after a RecoverPoint solution is implemented is the ongoing Protection Window value for your Consistency Groups.

EMC-VNX 1/2 and ESXi: Potential Data Unavailability
Another ETA hit my inbox over the weekend, this time relating to VNX/VNX2 and ESXi where a condition that could result in data being unavailable exists.

EMC RecoverPoint- Scripting bulk changes to Consistency Groups
It’s always nice to be able to make bulk changes to multiple devices. Most RecoverPoint environments will have a collection of Consistency Groups that could be as much as 128. To change a common configuration for all of them would take waaaay too long for my liking. A common option Continue Reading
