Hitachi Compatible PAV for Mainframe permits multiple applications running on an IBM z/OS or S/390® server to access the same information simultaneously. Multiple allegiance (MA) extends this capability to applications running on multiple z/OS or S/390 servers. Together, Compatible PAV (parallel access volumes) software for mainframe and MA reduce queuing, which results in significantly decreased batch times and lightning-fast responses in today's high transaction environments.
