IBM ATS Storage What is Hyper. Swap ? Why Hyper. Swap ? Ability to swap enterprise class System z™ data centers in a matter of seconds 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. ü Hyper. Swap substitutes Metro Mirror secondary for primary device ü No operator interaction, Hyper. Swap managed. ü Scales to multi-thousands of z/OS® volumes ü Includes volumes with SYSRES, page data sets, catalogs GB / Subsystem 70000 60000 ü Non-disruptive - applications keep using same ü Masks Applications from Disk Subsystem üGDPS/PPRC with Hyper.
