Product Overview
The Sun StorageTek Virtual Storage Manager® (VSM®) is a disk-based virtual tape sys-
tem that provides enterprise-class storage management capabilities for MVS-based sys-
tems. Its scalable design, which includes Virtual Tape Control System (VTCS) host soft-
ware and an intelligent Virtual Tape Storage Subsystem (VTSS) disk buffer, optimizes
streaming workloads and backup and recovery functions, reduces management over-
head, and maximizes tape capacity utilization to reduce data protection costs in a wide
range of storage environments.
