This IBM® Redpaper™ publication will help you plan, install, tailor and configure the new PowerHA® with Hyperswap clustering solution.
PowerHA with HyperSwap® adds transparent storage protection for replicated storage, improving overal system availability by masking storage failures.
The PowerHA cluster is an Extended Distance cluster with two sites which manages in principal the replicated storage infrastructure through HyperSwap functionality.
The storage is provided by two DS8800 configured to replicate each other using Metro Mirror (PPRC - Peer-to-Peer remote Copy) - synchronous replication. DS8800 supports in-band (SCSI commands) communication which is used to manage (and automate) the replication using AIX® HyperSwap framework and PowerHA automation and management capabilities.
