PowerHA SystemMirror for i Express Edition
New with IBM i 7.2 is the express edition of IBM PowerHA System Mirror. This edition is designed to be the foundation for a class of disaster recovery offerings based on restarting the LPAR into another LPAR on a different server for DR operations. The express edition differs from the standard edition in that the database is not placed into an IASP separate from SYSBAS. Rather, a primary LPAR is restarted or IPLd to a target LPAR on another server. With PowerHA 7.2 for i, the first stage of the express edition offering enables single node full system IBM HyperSwap® with the IBM DS8700 (and above) which provides customers with continuously available storage through either planned or unplanned storage events. With HyperSwap technologies, the act of moving between storage servers is nearly seamless.
