1. High Availability Options with Storage
What is HyperSwap ?
Ability to swap enterprise class System z™ data centers in a matter of seconds
HyperSwap substitutes Metro Mirror secondary for primary device
No operator interaction, HyperSwap managed.
Scales to multi-thousands of z/OS® volumes
Includes volumes with SYSRES, page data sets, catalogs
Non-disruptive - applications keep using same device addresses\
Masks Applications from Disk Subsystem Failures
GDPS HyperSwap integration with GDPS/MGM Incremental Resync & GDPS/MzGM Inc Resync.
GDPS HS Supports: z/OS®, z/VM®, zLinux
GDPS HS Mgr supports z/OS
z/OS Basic HS Supports z/OS
TPC-R 4.2 HS Supports z/OS & AIX OpenSwap
Why HyperSwap ?
The amount of storage / disk subsystem has dramatically increased to provide improved price / performance, and this has increased the business impact when a disk subsystem fails.

Parallel Sysplex is designed to provide near-continuous availability of systems, servers and applications within a single site (degree of availability depends on exploitation of Parallel Sysplex).
An end-to-end business continuity program is only as strong as its weakest link.
