OPTI-TAPE

Virtual Tape Drive Support for VSE/SP and VSE/ESA

OPTI-TAPE is a product designed to provide VSE/SP and VSE/ESA with virtual tape drive support. VSE/SP or VSE/ESA can use these virtual tape devices just as if they were real tape drives. Reads and writes to a virtual tape drive is intercepted at the channel program level providing a completely transparent interface. Data written or read from these virtual tape drives is re-directed to or from VSAM ESDS files. No changes to application programs or JCL is required.

Virtual Robotic Tape Silo

When OPTI-TAPE is used with BIM-EPIC, CA-EPIC or CA-DYNAM/T, OPTI-TAPE virtual tape drives appear to be part of a virtual robotic tape silo. When the tape management system processes a tape open request, it will always ask the silo (OPTI-TAPE) to mount the requested volume or scatch tape first. If the requested volume or scratch tape is available, OPTI-TAPE will automatically mount it on a virtual tape drive. If the requested volume or scratch tape is not available, normal tape manager processing will continue and the operator will be asked to mount a tape.
