Developments of the week in storage

Data Domain this week announced that with its new operating system, deduplication of data with its appliances can take place by as much as 50% to 100% faster.

The company is introducing DD OS 4.6 at no charge to its customers that have maintenance agreements. The operating system uses Stream Informed Segment Layout (SISL), a proprietary technology, which allows it to increase throughput with a minimum of system and disk hardware.

SISL is CPU-centric and hardware based and can increase performance without using additional controllers, compression hardware or extra disk.

The operating system applies across all Data Domain appliances and works with Symantec’s NetBackup OpenStorage API. A test of the DD690, with NetBackup API and 10Gb Ethernet, shows throughput during backup of 760Mbps or 2.7TB per hour, an increase of 90% over previous DD690s.

The DD120, Data Domain’s smallest model, shows a 100% improvement in performance with the new operating system. Other Data Domain appliances show a 50% to 90% increase in performance.
