Recovering from a Disk Failure

Organizations create disaster-recovery plans and procedures to protect against a variety of system failures, but disk failures tend to be the most common in networking environments. The technology used to create processor chips and memory chips has improved drastically over the past couple decades, minimizing the failure of systemboards. And while the quality of hard drives has also drastically improved over the years, because hard drives are constantly spinning, they have the most moving parts in a computer system and tend to be the items of most failure.

Key to a disk fault-tolerant solution is creating hardware fault tolerance on key server drives that can be recovered in case of failure. Information is stored ...
