摘要： A system and method for error correction and detection in a memory system. The system includes a memory controller, a plurality of memory modules and a mechanism. The memory modules are in communication with the memory controller and with a plurality of memory devices. The mechanism detects that one of the memory modules has failed possibly coincident with a memory device failure on an other of the memory modules. The mechanism allows the memory system to continue to run unimpaired in the presence of the memory module failure and the memory device failure.

摘要： Methods and systems for enhanced error recovery are described. A first one or more data blocks to write to a first drive are received by a first drive controller module. A first parity block is calculated by the first drive controller module based on a first data block parity group. The first one or more data blocks are written by the first drive controller module to the first drive. The first parity block is written by the first drive controller module to the first drive.

摘要： A method and system of method and system of enhanced RAID level 3 is disclosed. In one embodiment, a method includes allocating three times a physical storage capacity of a data drive to a dedicated parity drive of a ‘n’ physical drives of a redundant array of independent disks, recovering n−1 physical drive failures of the ‘n’ physical drives through a parity-in-parity technique in which certain number of parities generated during an initial write of data may be physically stored and using an XOR function applied to the stored parities to recreate un-stored parities which enable recovery of the n−1 physical drive failures. The method may include creating a superior read/write access capability and/or a superior parity data redundancy through the mirroring. The method may also include recreating the un-stored parities after a time interval that may be specified by a user.

摘要： A data storage subsystem that includes three data storage units, three check storage units, and an array controller coupled to the three data and three check storage units can tolerate failure of any three data and check storage units failures can be occur before data stored on the data storage subsystem is lost. Information is stored on the data storage subsystem as a symmetric Maximum Distance Separation code, such as a Winograd code, a Reed Solomon code, an EVENODD code or a derivative of an EVENODD code. The array controller determines the contents of the check storage units so that any three erasures of the data storage units and the check storage units can be corrected by the array controller. The array controller updates a block of data contained in any one of the data storage units and the check storage units using only six IO operations.

摘要： Error tolerance is increased for a storage system having a plurality of arrays by making local redundancy in a selected array globally available throughout the storage system. To achieve the increased error tolerance, a donor array is selected from the plurality of arrays when the difference between a minimum distance of the donor array and a minimum distance of a recipient array is greater or equal to 2. A donor storage unit is selected in the donor array and recipient information is then rebuilt from the recipient array on the selected storage unit. The selected storage unit is indicated to the donor array as having been donated before the lost information is rebuilt on the selected storage unit. Preferably, the minimum Hamming distance of the recipient array is d≧2 before the donor array is selected from the plurality of arrays.

摘要： When an amount of write data instructed by an upper-level system is small, a plurality of disk units are accessed individually and data split in sectors is written therein (Level 5 RAID). When an amount of write data instructed by the upper-level system is large, the plurality of disk units are accessed in parallel and data split in sectors is written therein (Level 3 RAID). When a disk unit in an array, to which a setup instruction is issued according to a processing request sent from the upper-level system, returns a fault reply, an ID management table is used to allocate an auxiliary disk instead of the failing disk unit. After the allocation, data is restored to the replacement disk using the data in normal disk units in the same rank. In a dual-port access configuration, when two transactions access disk units connected to the same port, a deadlock may occur depending on the access procedure. It is checked if the conditions for a deadlock are established, so that access will be obtained according to a procedure for preventing or avoiding a deadlock.
