SaaS data loss: The problem you didn’t know you had

Data Domain has replaced its 500-series mid-range and 120 entry-level deduplication products with new ones.

Data Domain is a subsidiary of EMC and manufactures deduplicating storage arrays. They carry out an in-line process deduplicating incoming data as it lands on the box rather than afterwards. The company is riding Intel's processor performance curve to steadily boost the performance of its products, and uses four-socket, quad-core Xeons in its range-topping DD880 box.

The mid-range was the Data Domain 500 series. It has been replaced at its upper end already with the DD580 giving way to the quad-core DD660 in March this year, following on from the introduction of the DD690 in May 2008. Both use quad-core Xeon processors to boost performance.

That left the DD500 series rump as the 565, 530 and 510. The 530 and 565 are replaced by the DD630, with 12TB raw capacity from its 1TB drives, and a 1.1TB aggregate backup throughput. The 510 is replaced by the DD610 with 6TB of raw capacity from 500GB drives, and 675GB/hour throughput.

This refresh would likely have been planned before EMC bought Data Domain. We still expect a new round of processor upgrades with 4- and 6-core Nehalem processors being adopted to raise performance further.

It is also expected or hoped that Data Domain will introduce global deduplication across members of its DDX arrays which currently deduplicate independently from each other.

The DD630, DD610 and DD140 are available immediately. No prices were revealed. ®
