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. 10000 20000 30000 40000 50000 60000 70000 2002 2003 2004 2005 2006 2007 2008 2009 GB / Subsystem High Availability Options with Storage GDPS/PPRC with HyperSwap™ Includes z/OS, z/VM, and zLinux Single site or 2-Site Configs GDPS/PPRC HS MGR – z/OS Only GDPS/PPRC w/HyperSwap GDS/MzGM w/HyperSwap GDPS/MGM w/HyperSwap GDPS/MGMM w/HS & GDPS/MzGMM w/HS z/OS Basic HyperSwap™ z/OS Data Only on same data center floor TPC-R HyperSwap™ z/OS Data Only on same data center floor or 2 site configs HyperSwap Benefits application UCB Metro Mirror P S Availability Extends Parallel Sysplex® availability to disk subsystems System Management Simplifies management of Remote Copy configuration, reducing storage management costs Reduces time required to implement remote copy Combines the features of Remote Copy management with the automation of GDPS or TPC-R.
