Solid-state devices may command most of the headlines in enterprise storage drive technology, but Seagate Technology continues to come up with new capabilities for age-old spinning disks.
The Seagate Exos Corvault petabyte-scale block storage array, due to ship in July, adds autonomous drive regeneration (ADR) technology that the company claims can bring most failing hard disks back into service without a manual drive swap. The ADR-based system can reconfigure the hard disk drive (HDD) to bypass the errant components.
Although the self-healing technology can’t provide a fix for every type of HDD problem — such as failures involving the drive’s interface or the system on a chip — it would address a bad drive head, one of the top causes of HDD failures, according to Ted Oade, director of global product marketing at Seagate.
“If a head goes bad in a conventional RAID array, that drive must be replaced. So, that’s what we’re avoiding,” Oade said.
