RAID Levels in OS
RAID Levels in OS Introduction: RAID stands for Redundant Array of Inexpensive (or Independent) Disks in an operating system. Redundant means having multiple copies of the same data. Storage media is becoming expensive and smaller in size, day by day. A computer system can store large amounts of data on multiple disks. Today, it is possible to attach multiple to a computer in parallel. In this way, multiple disks (or an array of disks) operate i ndependently and in parallel. So the performance and reliability of the system are improved. Explanation: With multiple disks, separate I/O requests can be handled in parallel to access data to and from the separate multiple disks. Similarly, a single I/O request can be executed in the parcel if the block of data to be accessed is distributed across multiple disks. With the use of multiple disks in a system, data can be organized in several ways and the redundancy can be increased to improve the reliability of data storage. Because redund...
