NAS System 1.3 RAID Concepts RAID Fundamentals The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive. The array of drives appears to the host computer as a single logical drive.

NAS System Definition of RAID Levels RAID 0 is typically defined as a group of striped disk drives without parity or data redundancy. RAID 0 arrays can be configured with large stripes for multi-user environments or small stripes for single-user systems that access long sequential records. RAID 0 arrays deliver the best data storage efficiency and performance of any array type.

NAS System Under RAID 5 parity information is distributed across all the drives. Since there is no dedicated parity drive, all drives contain data and read operations can be overlapped on every drive in the array. Write operations will typically access one data drive and one parity drive.

NAS System In summary: RAID 0 is the fastest and most efficient array type but offers no fault-tolerance. RAID 0 requires a minimum of one drive. RAID 1 is the best choice for performance-critical, fault-tolerant environments. RAID 1 is the only choice for fault-tolerance if no more than two drives are used. RAID 5 combines efficient, fault-tolerant data storage with good performance ...
NAS System RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. RAID Level Description Min. Drives Block striping is provided, which yields higher performance than with individual drives. There is no redundancy.
NAS System 1.4 High Availability 1.4.1 Creating Hot Spares A hot spare drive is an unused online available drive, which is ready to replace a failed disk drive. In a RAID level 1, 10, or 5 Raid Set, any unused online available drive installed but not belonging to a Raid Set can be defined as a hot spare drive.
