2-Understanding RAID Chapter 2. Understanding RAID The RAIDBank4 controller subsystem is a high-performance SATA2 drive bus disk array controller. When properly configured, the RAIDBank4 can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. The RAIDBank4 can be configured to RAID levels 0, 1, 10, 3, and 5, as well as disk spans and direct mapping. RAID levels other than 0 are able to tolerate a hard dis

2-Understanding RAID RAID 0 (Striping) This RAID algorithm writes data across multiple disk driv es instead of just one disk driv e. RAID 0 does not provide any data redundancy, but does offer the best high-speed data throughput. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array. Pros: Disk striping enhances both read and write performance because multiple drives are accessed simultaneously, Cons: The reliability of RAID Level 0

2-Understanding RAID RAID 3 RAID 3 provides disk striping and complete data fault tolerance though a dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates parity on the blocks, and then writes the blocks to all but one drive in the array. The parity data created is then written to the last drive in the array. If a single drive fails, data is still available by computing the inverse operation on the data and parity of the contents corresponding strips of the survi

2-Understanding RAID Volume Set A Volume Set is seen by the host system as a single logical device. It is organized in a RAID level with one or more physical disks. RAID level refers to the level of data performance and protection of a Volume Set. A Volume Set capacity can consume all or a portion of the disk capacity available in a RAID Set. Multiple Volume Sets can exist Free Space on a group of disks in a RAID Set. Volume 1 Additional Volume Sets created in a Data Data Parity Data spe

2-Understanding RAID Hot Swappable Disk support Your RAIDBank4 has a built in protection circuit to support replacement of disk drives without having to shut down or reboot the RAID. In case of drive failure, the failed drive can be removed from the RAIDBank4 and replaced with a new drive without disrupting dataflow to the host computer. Instant Availability/Background Initialization RAID 0 and RAID 1 volume set can be used immediately after the creation, whereas RAID 3 and 5 volume sets mus
