The following features were introduced with the PowerMaxOS 10 July 2022 release and Solutions Enabler/Unisphere for PowerMax 10.0.
Support for 2K SRDF Groups
Increases the number of configurable and operational SRDF groups from 250 to 2048 (2K).
Benefits
- Provides customers with far greater granularity between hosts/storage groups and SRDF groups.
- A 1:1 host/SG to SRDF group correspondence may now be possible for many environments.
- Allows a greater level of SRDF management, control, and monitoring granularity.
- PowerMaxOS 10 array to PowerMax/VMAX array will connect using the existing 1-250 group range.
- There is no planned support for connections to V2 VMAX arrays.
- The supported number of Remote Machines expands from 32 to 64.
Requirements
- Two or more PowerMaxOS 10 (2500/8500) or greater arrays per currently supported modes and topologies
- Solutions Enabler 10.0, REST API 10.0, or Unisphere for PowerMax 10.0
Functionality
- SRDF groups now accept enumerated values from the previous 250 groups to 2k groups (specifically a range of 1-2048).
- SRDF Add and Modify SRDF group Unisphere dialog, SYMCLI commands (such as symrdf addgroup -rdfg xxx …), and REST API calls have been modified.
- PowerMax V4 will connect to previous V3 arrays using the 1-250 group range with no support for connections back to V2 systems.
Important! V3 systems are unable to “see” groups beyond 250. 250 group support back to V3 arrays will be a limiting factor in your planning for SRDF and NDM support (not a factor to O-MDM). Verify that you have sufficient unused groups on the V3 prior to initiating SRDF connections with V4 systems.
- The number of Remote Machines (remote V4/V3 to which each V4 can connect) expands from 32 to 64.
RPM deployment for virtual witness
- Pre PowerMaxOS 10 deployment is only possible on ESX infrastructure.
- Customers require more flexibility for deployment infrastructure.
- Allows deployment on a Linux VM, irrespective of the hypervisor.
- Unisphere 10.0 is required (no microcode dependency, 597x, PowerMaxOS 10)
