16. Disk Spanning Performance improvements come from multiple areas including disk striping and disk spanning accessing multiple disks simultaneously and setting the percentage of processing capability to use for a task Disk striping writes data across all of the physical disks in the array into fixed size partitions or stripes In most cases the stripe size is user defined Stripes do not provide redundancy but improve performance since striping allows multiple physical drives to be accessed at the same time These stripes are interleaved in a repeated sequential manner and the controller knows where data is stored The same stripe size should be kept across RAID arrays Terms used with strip sizing are listed below Strip size One disk section Stripe size Total of one set of strips across all data disks not including parity stripes Stripe width The number of disks involved Disk spanning allows more than one array to be combined into a single virtual drive The spanned arrays must have the same stripe size and must be contiguous Spanning alone does not provide redundancy but RAID modes 10 50 and 60 all have redundancy provided in their pre spanned arrays through RAID 1 5 or 6 Note Spanning two contiguous RAID 0 drives does not produce a new RAID level or add fault tolerance It does increase the size of the virtual volume and improves performance by doubling the number of spindles Spanning for RAID 10 RAID 50 and RAID 60 re

19. RAID mode 0 is not fault tolerant With RAID 0 if a drive fails then the data is no longer complete and no longer available Backplane fault tolerance can be achieved by a spanned array where the arrays are on different backplanes True fault tolerance includes the automatic ability to restore the RAID array to redundancy so that another drive failure will not destroy its usability True fault tolerance requires the availability of a spare disk that the controller can add to the array and use to rebuild the array with the data from the failed drive This spare disk is called a hot spare It must be a part of the array before a disk failure occurs A hot spare drive is a physical drive that is maintained by the RAID controller but not actually used for data storage in the array unless another drive fails Upon failure of one of the array s physical drives the hot spare drive is used to hold the recreated data and restore data redundancy Hot spare drives can be global available to any array on a controller or dedicated only usable by one array There can be more than one hot spare per array and the drive of the closest capacity is used If both dedicated and global hot spare drives are available then the dedicated drive is used first If the hot swap rebuild fails then that hot spare is also marked failed Since RAID 0 is not redundant there is no hot spare value If a hot spare drive is not an option then it is possible to perform a hot or
