System makes use of maximum storage space

StorageTek's V960 Shared Virtual Disk Array System holds up to 4.3T of data.

The V960 Shared Virtual Array Disk System from Storage Technology Corp. holds 170G to 4.3T of data with full device-level virtualization.

That means all available space in a storage pool is usable, said Mark Peters, the Louisville, Colo., company's director of disk marketing. The logical and physical views of a device are separate. A user's assigned f: drive, for example, might not correspond to a physical drive.

In conventional disk systems, users get a certain disk allocation regardless of whether they fill it. The practice often leaves 35 percent to 50 percent of available space idle, Peters said.

The StorageTek V960 writes the data in the order in which it's created so that the administrator can fill a 1T system with 1T of data, Peters said. The users still have their own allocations.

'You manage one thing, which is the 'gas gauge,' ' Peters said.

The V960 uses RAID Level 6, a dual-parity version of RAID 5 with greater fault tolerance. Three drives would have to fail simultaneously to lose any data, and that is highly unlikely to happen, Peters said.

The 18G disk drives from IBM Corp. can compress up to 72G per physical drive. StorageTek chose the 10,000-rpm drives for fast seek times, Peters said.

The V960 connects to servers and storage area networks through Fibre Channel, IBM's optical-fiber Enterprise Systems Connection or a combination of the two. Compatible operating systems include IBM OS/390 and AIX 4.3.3, Sun Solaris 2.6, Hewlett-Packard HP-UX 11.0, Microsoft Windows NT 4.0 and Windows 2000.
