4. Arrays of Independent Disks disk array subsystem It consists of a RAID disk array controller and sixteen 16 disk trays The subsystem is a Host Independent RAID subsystem supporting RAID lev els 0 1 0 1 3 5 6 30 50 60 and JBOD Regardless of the RAID level the subsystem is configured for each RAID array consists of a set of disks which to the user appears to be a single large disk capacity One unique feature of these RAID levels is that data is spread across separate disks as a result of the redundant manner in which data is stored in a RAID array If a disk in the RAID array fails the subsystem continues to function without any risk of data loss This is because redundant information is stored separately from the data This redundant information will then be used to re construct any data that was stored on a failed disk In other words the sub system can tolerate the failure of a drive without losing data while operating independently of each other The subsystem is also equipped with an environment controller which is ca pable of accurately monitoring the internal environment of the subsystem such as its power supplies fans temperatures and voltages The disk trays allow you to install any type of 3 5 inch hard drive Its modular design allows hot swapping of hard drives without interrupting the subsystem s operation 1 1 Key Features Subsystem Features CR Features an Intel IOP341 800Mhz 64 BIT RISC I O processo

14. w Se L Paralled access decreases data transfer time for long sequential records 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 However because different records store their parity on different drives write operations can usually be overlapped Writes require parity to be updated tits DATA DATA DATA DATA DATA e PARITY PARITY PARITY PARITY PARITY e tii ddd Reads can occur simultaneously on every drive RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity information to the physical drives in the array With RAID 6 however two sets of parity data are used These two sets are different and each set occupies a Capacity equivalent to that of one of the constituent drives The main advantages of RAID 6 is High data availability any two drives can fail without loss of critical data Writes require parity to be updated DATA f DATA DATA f DATA DATA DATA PARITY PARITY PARTY PARTY PARITY PARITY Reads can occur simultaneously on every drive 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 RAI
15. D 0 These arrays are sometimes referred to as RAID 0 1 or RAID 10 and RAID 0 5 or RAID 50 In summary COR COR RAID 0 is the fastest and most efficient array type but offers no fault tolerance RAID 0 requires a minimum of two drives 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 3 can be used to speed up data transfer and provide fault tolerance in single user environments that access long sequential records However RAID 3 does not allow overlapping of multiple I O operations and requires synchronized spindle drives to avoid performance degradation with short records RAID 5 with a small stripe size offers similar performance RAID 5 combines efficient fault tolerant data storage with good performance characteristics However write performance and performance during drive failure is slower than with RAID 1 Rebuild operations also require more time than with RAID 1 because parity information is also reconstructed At least three drives are required for RAID 5 arrays RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme two dimensional parity Data is striped on a block level across a set of drives just like in RAID 5 and a second set of parity is calculated and written across all the drives RAID 6 provides
