- IBM Extended Command-Line Interface (XCLI) utility 5.2.0 or later
HyperSwap
HyperSwap® delivers highly-available, non-disruptive storage service, through partial or complete system failures and disasters, in the same data center and between metro-distant data centers.
HyperSwap high availability is based on active-active pairing of storage systems per volume or per consistency group. Each volume or consistency group pair uses synchronous replication to keep both systems updated at all times.
For more information, see High availability with HyperSwap.

Synchronous mirroring (two systems)
The process of ensuring that both storage systems contain identical data at all times is called remote mirroring. Synchronous remote mirroring provides continuous availability of critical information in the case of a disaster scenario. For more information, see Synchronous remote mirroring.

Asynchronous mirroring (two systems)
Asynchronous mirroring enables you to attain high availability of critical data through a process that asynchronously replicates updated data from a primary storage peer to a remote, secondary peer. For more information, see Asynchronous remote mirroring.

IBM Hyper-Scale Mobility
- Migrating data out of an over-provisioned system.
- Migrating all the data from a system that will be decommissioned or re-purposed.
- Migrating data to another storage system to achieve adequate (lower or higher) performance, or to load-balance systems to ensure uniform performance.
- Migrating data to another storage system to load-balance capacity utilization.
For more information, see IBM Hyper-Scale Mobility.
