Product Description

HP StorageWorks XP for Compatible Parallel Access Volumes Software (PAV) enables high performance concurrent access of mainframe volumes by permitting a mainframe host system to issue multiple I/O requests in parallel to individual logical devices within the HP StorageWorks XP Disk Array. Without PAV, mainframe systems can initiate only one I/O request per device at a time, and must wait for the I/O to complete before starting another I/O request to the same device. Utilizing alias addresses that all point to the same device as the base address, PAV enables the host system to start several I/O requests simultaneously to the same device, thus greatly improving performance. The HP StorageWorks XP Disk Array supports both static and dynamic PAV. With static PAV, the number of aliases assigned to each base device does not change. However, with dynamic PAV, high workload base devices can borrow idle PAV aliases from other base devices, increasing their I/O capability.
