Vendors Spout Virtual in San Francisco

SAN FRANCISCO -- Virtualization is high on the agenda at the Storage Decisions show in San Francisco this week, as vendors attempt to prove that the mainframe is alive and kicking, and hitch virtual servers to storage.

Sun Makes Mainframe Virtualization Move

Sun added some more flesh to the bones of its virtualization strategy today, overhauling its Virtual Storage Manager (VSM) mainframe VTL product.

The vendor claims that the souped-up VSM offers 53 percent more throughput than the previous version of the system, which was released last year. VSM is now capable of transferring data at up to 613 Mbytes/sec, according to the vendor.

Based on technology acquired when Sun bought StorageTek for $4.1 billion in 2005, VSM is a virtual tape system, which competes with IBM's recently enhanced TS7740.
