Mainframe Enablers version 8.3 also delivered several enhancements to zDP, expanding management capabilities of existing z/OS structures and security parameters. Enhancements included:
- Secure Snapsets: zDP builds on top of SnapVX secure Snapshot capability. With zDP secure snapsets, customers can set an expiration interval on the zDP Snapset. With the expiration interval set, the snapset will be terminated by Hypermax OS only when the expiration interval expires and cannot be terminated from a host command. This provides increased security to your most critical data that zDP manages. The new parameters to set your snapsets to a secure state are explained in the SnapVX and zDP Product Guide.
- Five Minute Cycle Time: Cycle time enables customers to specify how often zDP should create a snapset. Previous to Mainframe Enablers 8.3, customers set the zDP cycle time to no less than 10 minutes. This enhancement will enable customers to set the cycle time as low as five minutes enabling more granular copies of your data.
- COPY_ONCE VDG Parameter: This parameter will increase space savings for your zDP snapsets because enables customers to identify which data to snapped once and not needed for every snapset iteration.
- The ability to define a VDG and Target group by specifying an SRDF Group: Customers today use SRDF groups when working within PowerMax and VMAX All Flash. This enhancement will enable customers to use existing SRDF Groups to define and manage VDG and Target groups.
zDP has also made significant enhancements to how various commands are processed by the PowerMax and VMAX 950 All Flash Array. The result of these enhancements will improve performance for the QUERY and ACTIVATE commands. For more information about enhancements, refer to latest Product Guide for SnapVX and zDP.
