  • Page 20: Raid Overview

    StorageWorks RAID Array 200 Subsystem Family RAID Overview RAID (redundant array of independent disks) is a modular, integrated, end-user solution that provides three main benefits: • Improved data availability • Improved I/O performance • Increased scaleability A RAID array is a set of multiple disk drives and a specialized array controller that manages how data is distributed across disk drives.

  • Page 21: Raid 0 + 1

    Chapter 1 Raid 0 + 1 RAID 0 + 1 is achieved in a multidrive RAID set by the combination of striping mirrored sets. RAID 0 + 1 provides data redundancy and is beneficial for any critical high-availability application. If a drive fails in a RAID 0 + 1 array, you can continue to use the array normally since data from its mirrored drive is automatically retrieved.

    Chapter 5 Manual Rebuild of a Drive (Reconstruction) A rebuild is a process of recreating data on a new drive in a configuration with a redundant RAID level (for example, RAID 1, RAID 0 + 1, and RAID 5). If your logical RAID drive was configured with a RAID level that does not support data redundancy, all data is lost if a drive fails.
