The following PowerMaxOS Q3 2020 release introduced many enhancements to SnapVX, including the following:
Snapshot policies: Automated, compliance-based snapshot protection for applications.
Increased session limits: Snapshot policies support up to 1024 snapshots per source volume.
Cloud snapshots: Cloud Mobility for Dell EMC PowerMax provides open-systems snapshot movement to and from private and public clouds (Dell EMC ECS, AWS, Microsoft Azure) for recovering data back to the array and consumed it directly in AWS.
SnapSet: A set of consistent snapshots that are taken together. For example, when a snapshot is taken of an SG that contains 10 devices, the resulting SnapSet consists of 10 consistent snapshots.
SnapSet ID: A system-generated number that is applied to consistent snapshots across the volumes in a SnapSet. When a snapshot is taken of an SG, all resulting snapshots have the same SnapSet ID. The SnapSet ID is an absolute value that does not adjust as other snapshots are created or terminated.
Bulk terminate: A Unisphere term for functionality that allows termination of many snapshots of an SG in a single operation.
Snapshot SRP Utilization Alert: Unisphere alert that triggers on preset threshold values for overall snapshot usage across the entire SRP and for designated SGs.
Interoperability of nocopy linked and SRDF: Support for using an SRDF R1 as a nocopy linked target. Prior code releases require an SRDF R1 to be linked in full copy mode.
