Focus on Storage “VTFM brings some intriguing technologies to the mainframe that allow the entire storage and retention process to be accelerated greatly because of some of the technologies that exist under the covers.” —Michael Demain, product offering manager for IBM Enterprise Storage Marketing area by acquir ing Fram ingham, Mass.-based Di ligent Technologies, bringing on board the company’s cuttingedge technologies, including Vir t ual Tape Facilit y for Mainframe (VTFM), an offering that mimics IBM-compatible car tridges and tape volumes on z/OS* mainframes and transparently transfers tape data to disk. The product was officially announced in November, after IBM made VTFM compat ible w it h its ex ist ing product standards. More i n for m at ion about t he a n nou nc e me nt c a n b e fou nd on line in t he ar ticle “Welcome to Storage 2.0” (w w w. ibmsystemsmag.com/mainframe/novemberdecember08/ focusonstorage/22325p1.aspx). “Diligent had established itself as having technologies that were accepted as cutting edge in terms of data de-duplication, which means, in perhaps overly simplistic terms, we are able to take data that’s retained and reduce the amount of space required to store that data over time by eliminating duplicate data elements,” says Michael Demain, product offering manager for IBM Enterprise Storage Marketing, Systems and Technology Group. “While that particular technology is available today mainly for the open-systems platforms, Diligent also brought several other products to the table as well, one of which was Virtual Tape Facility for Mainframe. V TFM brings some intriguing technologies to the mainframe that allow the entire storage and retention process to be accelerated greatly because of some of the technologies that exist under the covers.” From Tape to Disk—Faster At its most basic level, VTFM allows customers to continue using tape storage while using disk as a backup target, which enables customers to leverage the cost-efficiencies disk solutions provide for near-term data recovery and the performance gained in batch processing. By emulating I BM- compat ible t ape -pr oc e s si ng f u nc t ion s for z / OS platforms, VTFM can seamlessly integrate into a physical tape environment without requir ing changes to the code or applications. Because V T FM operates free of hardware restrictions and supports all industry-standard disk-storage subsystems, it offers the freedom to use V TFM with any existing 3390 format ESCON* or fiber connectivity (FICON) disk array. It also emulates many tape devices—including 3480, 3490 and 3590—and operates completely transparent to the host, applications, tape-management systems and users. In addition to its tape-to-disk storage functionality, V T FM provides enhanced features such as shared tape access using Parallel Access Tape and advanced spacemanagement tools using Virtual Tape Analyzer.
