TelTape for z/OS

The architecture of TelTape for z/OS is designed for high performance and reliability within z/OS environments. The main components include the Tape Management Subsystem, the Virtual Tape Server (VTS) module, and the High-Speed Copy Engine. The Tape Management Subsystem provides the core functionality for managing tape resources, including allocation, deallocation, and tracking.

The VTS module emulates physical tape drives, allowing data to be stored and retrieved on virtual tapes. The High-Speed Copy Engine utilizes optimized algorithms and direct data transfer methods to perform tape-to-tape copies at significantly faster speeds. Communication between components is primarily through z/OS system calls and internal interfaces.

The system uses standard z/OS datasets for configuration and logging. The CLI provides the primary administrative interface. Security is implemented through RACF integration and RBAC, ensuring that access to tape management functions is controlled and auditable.

The High-Speed Copy Engine is a key differentiator, providing superior performance compared to some competitors. For example, the `TAPE COPY` command leverages the High-Speed Copy Engine for rapid data replication. The VTS module improves data access times and simplifies tape library management.
