Mike, Of course you can have a full-functional "virtual tape" solution without the hardware, its called CA-Vtape ;}
With CA-Vtape, you use your existing DASD as the cache for staging the virtual volumes but how much cache you have will depend on how quickly you want to backstore to the physical tape(s). The more cache you have, the less often you would need to perform the backstore operation. And, it is not priced on a MIPS basis; but rather on how many virtual-UCB's you need. So, it is very easy to scale it to your needs. Very similar to TMM (which will also use your dasd as the staging place); but doesn't require any JCL changes or even any SMS construct changes.

Currently we are using a StorageTek VSM unit, which we would like to get rid of. Does anyone know if it is possible to create and manage virtual tape functions using the above without the VSM hardware? If so, can you provide me some references that would help in the implementation?
