Parallel Access Volume support in z/VSE

I just got a question about z/VSE's Parallel Access Volume (PAV) support.
A few facts about our PAV support:
Parallel Access Volume (PAV) is an optional licensed feature on the IBM System Storage. Parallel access volumes are managed by creating multiple addresses for a single logical device. z/VSE supports one base device and up to 7 alias devices. With basic PAV support for ECKD devices z/VSE can access such a PAV device in parallel, which allow more than one I/O operation to be processed for a single logical device. This may give significant performance benefits dependent on your workload.
More information about z/VSE's PAV support is described in "Configuring Your System to Use PAV” of the z/VSE 6.2 Administration book in the PDF library of the z/VSE Knowledge Center and in the white paper, here.
z/VSE does not support HyperPAV.
Information about z/VM's PAV support is here.
