Seagate Introduces Groundbreaking Exos CORVAULT Hardware-Based Self-Healing Block Storage System

[btarunr]

Seagate, a world leader in data storage infrastructure solutions, launched a uniquely intelligent category of mass-capacity storage designed to streamline data management and reduce human intervention for macro edge and data center environments. The new Exos CORVAULT high-density storage system offers SAN-level performance built on Seagate's breakthrough storage architecture that combines the sixth generation VelosCT ASIC, ADAPT erasure code data protection, and Autonomous Drive Regeneration.

Designed on the Seagate Exos 4U106 12 Gb/s platform, CORVAULT offers "five nines" availability (99.999%) helping to deliver consistently high reliability. The maximum-density 4U chassis accommodates 106 drives in only seven inches (18 cm) of rack space. It is tuned to maximize drive performance by protecting against vibrational and acoustic interference, heat, and power irregularities.



Seagate's new VelosCT chip powers the system's dual storage controllers, which optimizes all drive actuators in parallel, driving superior performance while Seagate's Advanced Distributed Autonomic Protection Technology (ADAPT) distributes data across every drive offering advanced data protection and fast rebuilds without sacrificing performance.

Autonomous Drive Regeneration (ADR) is a self-correcting system that renews a drive in-situ without the need for a manual drive swap. Developed by Seagate, ADR can return most drives to dependable service by reconfiguring the drive to bypass errant components. The technology also helps reduce the environmental impact of computer e-waste as ADR drives are renewed instead of discarded.

CORVAULT will be available globally via qualified Seagate distributors in July.

Is ADR means if a drive had bad sector, it will automatically format the drive and the bad sector will be isolated in the formatting process so the "renewed" drive lost a little bit of capacity but now "Healthy" again to be re-introduced into the Raid ?

it's a new game from Bethesda, about survival after an apocalypse, but with a twist, agriculture and farming simulator is core to this one's gameplay.

According to a memo I read few days ago, it mostly concern with immediate depopulation of failed drive head.
There may be other component ADR can bypass, but the most significant one should be drive heads (provided that there are more than one).

I see.

I am curious about how this affects performance tho, since most of the "speed" of the HDD comes from drive heads running in parallel.
Disabling drive head = double digit speed lost = becoming the shortest plank of the barrel (RAID pool)
Dunno if the so-called " reduce the environmental impact" is worth having the whole RAID pool suffering performance lost before the drive swap.

And, if a drive with a failed drive head can still be considered "Reliable" in operation ....................
