Access "Storage, heal thyself 2"
This article is part of the Vol. 8 Num. 4 June 2009 issue of Exploring systems that detect and repair hard disk problems automatically
Several storage system vendors claim their products can detect and repair hard disk problems automatically. Here's how they do it and the low-down on how well they work. A fundamental change in the basic building blocks of storage is occurring, one that's as groundbreaking today as RAID was when it was introduced 20 years or so ago. The revolutionary development is commonly referred to as "autonomic self-healing storage," and it promises greater reliability from disk systems than ever before. Autonomic self-healing storage might sound more like a trumped-up term than a fundamental change. After all hasn't it been around for a while in the form of RAID, redundant array of independent nodes (RAIN), snapshots, continuous data protection (CDP) and mirroring? If you define self-healing as the ability to restore from a failure situation, you'd be right. All of those familiar technologies are designed to restore data from a failure situation. But to be a bit more precise, those technologies are actually self-healing data, not self-healing storage. They restore data... Access >>>
