VTFM-NewGen

VTFM-NewGen employs a multi-tiered architecture to virtualize tape datasets on DASD. The core components include the VTFM server, VTFM control datasets, and the virtual tape repository. The VTFM server intercepts tape I/O requests and redirects them to virtual tape volumes stored in the repository.

The VTFM control datasets store metadata about virtual tapes, including location, size, and security attributes. The VTFM server communicates with z/OS systems using standard z/OS protocols. It integrates with z/OS security systems such as RACF, ACF2, and Top Secret for authentication and authorization, supporting role-based access control (RBAC).

Data is typically stored on DASD, and the system can be configured to use different types of DASD based on performance and capacity requirements. VTFM-NewGen does not expose public APIs like REST or SOAP. Integration is primarily achieved through standard z/OS interfaces and commands.

The system provides a command-line interface (CLI) and a web-based GUI for administrative tasks. Competing products may offer different architectural approaches, but VTFM-NewGen prioritizes seamless z/OS integration and minimal disruption to existing workflows. The architecture is designed for high availability and scalability.
