The I-6990 EVTS is a virtual tape storage server, controlled by the Virtual Storage Manager. It includes a hard disk cache and supports tape robots and optical disk libraries as well as offline archives. All components are under control of the I-6990 Virtual Storage Manager. Connectivity is provided to mainframes via ESCON and Block Multiplex Channel and to open systems platforms, including UNIX and Windows NT, via ATM and Gigabit Ethernet.
Virtual storage management permits multiple local and remote copies, to as many as four different media types. This Virtual Tape System allows the backend storage facilities to be silos, tape libraries, optical jukebox or even CD or DVD subsystems. Host software components are not needed. Operating system support includes IBM z/OS, MVS, VM, and VSE. A variety of tape backup and recovery software packages support the open virtual storage system capability.
