摘要： The error tolerance of an array of m storage units is increased by using a technique referred to as “dodging.” A plurality of k stripes are stored across the array of storage units in which each stripe has n+r elements that correspond to a symmetric code having a minimum Hamming distance d=r+1. Each respective element of a stripe is stored on a different storage unit. An element is selected when a difference between a minimum distance of the donor stripe and a minimum distance of a recipient stripe is greater or equal to 2. The selected element is also stored on a storage unit having no elements of the recipient stripe. A lost element of the recipient stripe is then rebuilt on the selected element.

摘要： A data cache for an iSCSI network caches block-level data from WAN servers for use by clients (e.g., LANs). The cache authenticates itself to the WAN servers, and authenticates clients requesting cache access. Mechanisms are provided to prevent clients from accessing cached data intended for other clients.

摘要： An optimum pathway to data stored on a data storage system having N storage devices and more than N pathways is determined in response to a read request for the data. A sorter separates the read request into an appropriate segment size for sending to the storage devices of the data storage system. An assigner generates the set of read permutations satisfying the read request. A read permutation is selected based on a metric. A collector receives the requested data from the N storage devices in response to the selected read permutation being sent to the storage devices.

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： Embodiments of the invention relate to a storage system cache with flash memory units organized in a RAID configuration. An aspect of the invention includes a storage system with a storage cache that includes flash memory units organized in an array configuration. The storage system further includes an array controller that manages data access and data operations for the flash memory units and organizes data as full array stripes. The storage system also includes a storage cache controller, that includes a block line manager that buffers write data to be cached for a write operation until the storage cache controller has accumulated an array band, and commits write data to the array controller as full array stripes. The storage cache controller determines whether to store write data for a write in the storage cache and/or in the primary storage device and whether to access read data from the storage cache or from the primary storage device.

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.
