Hitachi Extended Remote Copy for Mainframes Software
Hitachi Extended Remote Copy for Mainframe (XRC) provides disaster protection and data migration capability for data stored on the XP disk array system by implementing IBM mainframe compatible asynchronous remote replication. XRC provides the same functionality as IBM Extended Remote Copy (now called IBM TotalStorage z/OS Global Mirror), and is compatible with System Data Mover (SDM) mainframe software. When data is written to the local XP disk array, XRC temporarily stores a timestamped copy of it in a sidefile. SDM in one of the mainframe hosts asynchronously reads the sidefile data from the local XP disk array and then writes the data to the remote disk array
XRC can be combined with other XP disk array replication products for additional availability. When combined with Hitachi TrueCopy for Mainframe, XRC supports 3 Data Center disaster recovery solutions. In addition, XRC can be used with Hitachi ShadowImage for Mainframe or Hitachi FlashCopy Mirroring for Mainframe to maintain multiple copies of important data at the local and remote sites.
