[9] 1.4 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 ...

[10] 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 d...

[11] RAID 3 sector-stripes data across groups of drives, but one drive in the group is dedicated to storing parity information. RAID 3 relies on the embedded ECC in each sector for error detection. In the case of drive failure, data recovery is accomplished by calculating the exclusive OR (XOR) of t...

[12] Dual-level RAID achieves a balance between the increased data availability inherent in RAID 1 and RAID 5 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1 or RAID 10 and RAID 0+5 or RAID 50. RAID 6 is similar to RAID 5 in t...

[13] 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 0 Block striping is provide, which yields higher performance than with individual drives. There is no redundancy. 1...

[14] 1.5 Volume Relationship Diagram This diagram shows how the volume structure of the iSCSI RAID subsystem is designed. It describes the relationship of RAID components. One RG (RAID group) consists of a set of VDs (Virtual disk) and owns one RAID level attribute. Each RG can be divided into sever...
