摘要： An apparatus and method to manage redundant non-volatile storage (“NVS”) data backups in a data storage system comprising (n) clusters, wherein each cluster comprises a processor and a cache, and wherein each cache comprises a first NVS portion and a second NVS portion, wherein the method configures, for each value of (i), a primary NVS backup for an (i)th cluster, where that (i)th primary NVS backup comprises a first NVS portion of a cache disposed in an (i+1)th modulo (n) cluster, wherein (i) is greater than or equal to 0 and less than (n). The method further configures, for each value of (i), a secondary NVS backup for an (i)th cluster, where that (i)th secondary NVS backup comprises a second NVS portion of a cache disposed in an (i+2)th modulo (n) cluster.

摘要： Provided are a method, system, and article of manufacture for using device status information to takeover control of devices assigned to a node. A first processing unit communicates with a second processing unit. The first processing unit uses a first device accessible to both the first and second processing units and the second processing unit uses a second device accessible to both the first and second processing units. The first processing unit receives status on the second device from the first device indicating whether the second device is available or unavailable. The first processing unit detects a failure of the second processing unit and determines from the received status on the second device whether the first device is available in response to detecting the failure of the second processing unit. The first processing unit configures the second device for use by the first processing unit in response to determining that the received status on the second device indicates that the second device is available and in response to detecting the failure.

摘要： A method to access a data in a RAID array comprising a plurality of data storage media, wherein information is written to said plurality of data storage media using a RAID configuration, wherein the method receives from a requester a command comprising a data access priority indicator. If a RAID rebuild is in progress, the method determines if the data access priority indicator is set. If the data access priority indicator is set, the method executes a command selected from the group consisting of writing information to the target logical block array range, and returning to the requestor information read from the target logical block array range.

摘要： An apparatus for parity data management receives a write command and write data from a computing device. The apparatus also builds a parity control structure corresponding to updating a redundant disk array with the write data and stores the parity control structure in a persistent memory buffer of the computing device. The apparatus also updates the redundant disk array with the write data in accordance with a parity control map and restores the RAID controller parity map from the parity control structure as part of a data recovery operation if updating the redundant disk array with the write data is interrupted by a RAID controller failure resulting in a loss of the RAID controller parity map. In certain embodiments, the parity control structure is a RAID controller parity map.
