    [4] Chapter 1 Introduction The iSCSI RAID Subsystem The iSCSI RAID subsystem is a 4 -bay disk array based on hardware RAID configuration. It is an easy-to-use storage system which can be co nfigured to any RAID level. It provides reliable dat a protection f or servers, and the RAID 6 function is available. Th e RAID 6 function allow s failure of tw ...

    [9] 1.4 RAID Concepts RAID Fundamentals The basic idea of RAID (Redundant Array of Independent Disks) is to combine multipl e inexpensive disk driv es 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. Fiv ...

    [10] Definition of RAID Levels RAID 0 is typically defined as a group o f stripe d disk drives without parity or data redundancy. RAID 0 arrays can be config ured with large stripes for multi-us er environments or small stripe s for single-user systems th at access long sequential records. RAID 0 arrays delive r the best data storage effici ency an ...

    [11] RAID 3 sector-stripes data acros s groups of drives, but one drive in the group is dedicated to storing parity information. RA ID 3 relies on the embedded ECC in each sector for error detection. In the case of drive failure, data recovery is accomplish ed by calculating the exclu sive OR (XOR) of the inf ormation recorded on the remain ing dri ...

    [12] Dual-level RAI D achieves a balance between the incr eased data availability inherent in RAID 1 and RAID 5 and the increased read performance inherent i n 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 that data protection is achieved by writing par ...

    [13] RAID Management The subsystem can implement sev eral different levels of RAID technology . RAID levels supported by the subsystem are shown below. RAID Level Description Min. Drives 0 Block striping is provid e, which yields higher performance than with individual drives. There is no redundancy. 1 1 Drives are paired and mirrored. All data is ...
