StorageTek Library Extension For Mainframes Released

Oracle, which has not revealed much about how it intends to keep developing its Sun StorageTek franchise since the Sun Microsystems acquisition 10 months ago, introduced a new Virtual Library Extension that adds new-generation storage tiering into mainframe environments.

Oracle is positioning the new library extension as a highly scalable additional tier of disk and tape storage for mainframes, although it also can be used in open standards x86-based systems.

Twice The Scalability

Virtual storage libraries – which can include physical tape and various types of disk storage – all look the same to a virtualised storage system. These are most often considered Tier 2 storage for mainframes and Tier 3 or offline storage for x86 and Unix-based data centres, which most often rely on in-memory or solid-state Tier 1 storage for hot data and SATA hard disk storage for nearline, Tier 2 storage.

Oracle claimed that the library extension, which can handle Fibre Channel disks, SAS disks and physical tape storage, has twice the disk scalability of previous StorageTek libraries and five times the availability of IBM mainframe tape systems.

Like IBM, StorageTek is a data storage senior citizen that has earned its stripes in the enterprise over a span of two generations. “Since its inception more than 40 years ago, the StorageTek mainframe storage business has been a driving force behind innovation in the industry,” said John Fowler, former Sun hardware vice-president and now Oracle’s executive vice president of systems.

“This approach to mainframe tiered storage provides customers with a way to cost-effectively keep data on disk for longer time period while still leveraging the long-term cost savings of tape.”

Using the StorageTek VLE, customers can keep active data on disk longer before migrating it to tape for long-term storage, Fowler said. It can also be used for archiving.

StorageTek tape libraries can support both mainframe and open standards data centre environments within a single library. They integrate natively as a data protection package with Oracle Exadata Database Machine, Oracle 11g Recovery Manager and Oracle Secure Backup software running with Oracle Solaris and Oracle Linux.

The StorageTek library extension is available now, Oracle said.
