Sutmyn beefs up virtual tape
Anticipating the forthcoming entry of Storage Technology into the market, Sutmyn Storage Corp. this month will begin enhancing its line of Scimitar virtual tape systems. Scimitar will support up to eight ESCON channels, 64 virtual tape drives, and up to 1.5 terabytes (assuming 2:1 compression) of cache. In a virtual tape system, cache is implemented in a RAID array; in the case of Sutmyn`s Scimitar, the array is based on a subsystem from Data General`s Clariion unit.
Sutmyn was second to market a virtual tape system, following IBM. Sutmyn claims to have installed about 30 systems worldwide; IBM claims to have installed more than 300 of its Virtual Tape Servers. Storage Technology, the leading manufacturer of tape libraries, is expected to ship beta units of its Virtual Storage Manager in late March.
The major benefits of virtual tape systems are faster data access times due to the RAID cache, improved mounts per hour, better tape cartridge capacity utilization, and a reduction in the number of tape cartridges required. Another potential benefit is a lower total cost of ownership.
Sutmyn will phase in the enhancements over the next few months. For more information about virtual tape systems, see InfoStor, December 1997, p. 38, "The Virtues of Virtual Tape."--DS
