StorageTek Virtual Library Extension

Oracle has unveiled the StorageTek Virtual Library Extension, the industry’s first highly scalable second tier of disk storage that optimizes tape processing in mainframe environments. The StorageTek Virtual Library Extension expands the disk capacity of the StorageTek Virtual Storage Manager virtual tape environment to enable a secondary tier of disk-based performance while maintaining streamlined management. This addition provides as much as 3.5 PB of additional effective disk storage space, giving customers more-seamless disk buffer scalability to manage growth and increase performance while reducing costs.

The integrated StorageTek Virtual Storage Manager/StorageTek Virtual Library Extension environment is the only mainframe virtual tape solution to provide a single, policy-based management interface that migrates data between high-performance disk, high-capacity disk, and tape tiers.

The StorageTek Virtual Library Extension maximizes data protection and availability by leveraging the unique StorageTek Virtual Storage Manager architecture that enables data to be dynamically stored and protected in multiple tiers of storage and at multiple locations without involving the mainframe. The product uses Oracle Solaris ZFS technology to provide higher reliability with triple-parity RAID-Z3, which delivers five times more data reliability than IBM systems using RAID-6.

“Oracle continues to address the needs of mainframe virtual tape customers, ” says Robert, research director of data protection and recovery at International Data Corporation (IDC). “Oracle’s StorageTek Virtual Library Extension provides an innovative and cost-effective approach by adding a second tier of disk to its StorageTek Virtual Storage Manager products.”
