Storage Suppliers Push Scaleability Envelope

Expansions of capacity and performance are featured in announcements from a handful of storage vendors this week, indicating growing interest in systems that scale, particularly for companies with rich media requirements.

ExaGrid, for instance, today announced Version 3.0 of its disk-based de-duping backup platform, claiming substantial backup and restore performance of previous versions. At the same time, ExaGrid's boasting that it copes with the side effects of scaling by fitting all this into a footprint that's 50 percent to 75 percent smaller than before.

The vendor's achieved this feat, claim officials, by adding 750-Gbyte Seagate SATA drives in place of 500-Gbyte ones. "We've also made software more efficient, so it can do the same job with half the hardware," says Marc Crespi, VP of product management.

Crespi says customers with 20 Tbytes of data can expect to see backups at rates to 2.1 Tbytes per hour (583 Mbytes per second) and restore times of 1.5 Tbytes per hour (417 Mbytes per second). Both figures "used to be a shade over that."

No customers were available to testify about the actuality of ExaGrid's performance claims, or the relative advantages of the new platform.
