Hardware Requirements

CA Vtape requires a CPU capable of running with z/Architecture (ARCHLVL=2 in the LOADxx member of the IPL parmlib).

All mainframe DASD and tape devices are supported.

We recommend that RAID DASD with high band-width ratings and DASD Fast Write (DFW) activated be used for the DASD cache. Consult your vendor to find the device with the best performance rating.

Physical tapes are not required. CA Vtape can be configured to do the following:

• Stack Virtual Volumes on another virtual tape solution
• Transmit Virtual Volumes to a remote location (requires an additional license)
• Not stack at all.

If you choose to stack Virtual Volumes on physical tape, we recommend that robotic, high-capacity tape cartridges be used to improve performance.
