Gad 0 2 GB Hard Drive Logical Drive Figure A 1 JBOD A 3 2 RAID 0 RAID 0 implements block striping where data is broken into logical blocks and striped across several drives Although called RAID 0 this is not a true implementation of RAID because there is no facility for redundancy In the event of a disk failure data is lost In block striping the total disk capacity is equivalent to the sum of the capacities of all drives in the array This combination of drives appears to the system as a single logical drive RAID 0 provides the highest performance without redundancy It is fast because data can be simultaneously transferred to from multiple disks Furthermore read writes to different drives can be processed concurrently RAID 0 block striping is illustrated in Figure A 2 System Features A 3 Logical Drive Physical Disks Beck ma Block 3 Ea l Block 6 Block 6 Block 8 Block 8 i Figure A 2 RAID 0 A 3 3 RAID 1 RAID 1 implements disk mirroring where a copy of the same data is recorded onto two sets of striped drives By keeping two copies of data on separate disks or arrays data is protected against a disk failure If at any time a disk on either side fails the remaining good disk copy can provide all of the data needed thus preventing downtime In disk mirroring the total disk capacity is equivalent to half the sum of the capacities of all drives in the combination Thus combi

6. 3 A 3 6 RAID 5 RAID 5implements multiple block striping with distributed parity This RAID level offers the same redundancy available in RAID 3 though the parity information this time is distributed across all disks in the array Data and relative parity are never stored on the same disk In the event a disk fails original data can be reconstructed using the available parity information An illustration of RAID 5 striping with non dedicated parity is shown in Figure A 6 System Features A 7 Logical Drive Physical Disks Er eed Boks Bick Le Kaas Block 4 Bariy 6 4 as Block 6 Block Boz Block 6 Block 8 Figure A 6 RAID 5 RAID 5 offers increased data transfer rates when data is accessed in large chunks i e sequentially and reduced data access time for many simultaneous I O s when they do not span more than one drive A 3 7 RAID 30 and RAID 50 RAID 30 is a logical volume with RAID 3 logical drives RAID 50 is a logical volume with RAID 5 logical drives A 3 8 Non RAID Storage One common option for expanding disk storage capacity is simply to install multiple disk drives into the system and then combine them end to end This method is called disk spanning In disk spanning the total disk capacity is equivalent to the sum of the capacities of all drives in the combination This combination appears to the system as a single logical drive Thus combining four 1GB SATA drives in this way for examp
7. 4 RAID 1 0 1 IMPORTANT RAID 0 1 will not appear in the list of RAID levels supported by the controller If you wish to perform RAID 1 the controller will determine whether to perform RAID I or RAID 0 1 This will depend on the number of drives selected for the logical drive A 3 5 RAID 3 RAID 3 implements block striping with dedicated parity This RAID level breaks data into logical blocks the size of a disk block and then stripes these blocks across several drives One drive is dedicated to parity In the event a disk fails the original data can be reconstructed from the parity information In RAID 3 the total disk capacity is equivalent to the sum of the capacities of all drives in the combination excluding the parity drive Thus combining four 1GB SATA drives for example would create a single logical drive with a total disk capacity of 3GB This combination appears to the system as a single logical drive System Features RAID 3 provides increased data transfer rates when data is being accessed in large chunks or sequentially However in write operations that do not span multiple drives performance is reduced since the information stored in the parity drive needs to be re calculated and re written every time new data is written to any of the data disks RAID 3 striping with dedicated parity is shown in Figure A 5 Logical Drive Physical Disks ae we L Block 4 Block 4 lock 6 Figure A 5 RAID
