DirectData Networks fights silent SATA corruption

Hmmm…that title sounds more “crime fighter” than I was going for. Anyway,

DataDirect Networks announced today they’ve released DirectOS 3.08 with the SATAssure system for its S2A9550 SATA storage product. According to the company

The newly updated S2A9550 is the only storage array on the market that detects and corrects “silent data corruption” inherent in SATA drives by performing on-the-fly real-time parity checking on all read I/Os without incurring any performance penalty. This ensures absolute data integrity and enables the use of SATA drives in large, scalable pools that measure from 100 terabytes to several petabytes (one petabyte is 1,000 terabytes) in capacity.

A single S2A intelligent storage controller manages up to 960 SATA drives (nearly 1000 Terabytes of data) in two datacenter rack.

There are details about the technology in the release.
