RAIDBank4 Owner s Manual 56 D Glossary ATA Acronym for AT Bus Attachment a standard interface to IDE hard disks Western Digital s IDE disk interface was standardized by ANSI to form the ATA specification using a 16 bit ISA bus Cache cache is a fast access memory bank that serves as an intermediate storage for data that is read from or written to secondary storage Typically high speed caches are implemented in RAM though they can also be implemented on disk when speed is not a critical requirement Caches generally improve the efficiency of read operations due to the principles of spatial and temporal locality of data They can also improve the efficiency of write operations See also Write Back Cache Write Through Cache Degraded Mode Status All arrays with the exception of RAID 0 are designed to handle disk failures However there is limit on the number of hard disks that can fail before the array is rendered inoperative For instance this limit value is 1 for RAID 1 3 and 5 In the case of RAID 10 or 50 the upper bound is equal to the number of parity groups When the number of disk failures occurring in an array are less than or equal to this upper bound the array is denoted to be in a degraded state The failure of the disks does not impair reading from or writing to the array However it impairs the efficiency of throughput in all RAID types with the exception of RAID 1 since data requested by read operations
