摘要： A system and method for rebuilding a storage drive utilizes a rebuild management module within a RAID controller to conduct a substantially sequential rebuild operation on a rebuild disk. When the rebuild management module receives host I/O requests during a rebuild operation, these requests are facilitated using other disks. After the substantially sequential rebuild is complete, the rebuild management module updates the rebuild disk based upon the host I/O requests received during the sequential rebuild operation.

摘要： An architecture and method for executing write commands in a storage array is disclosed. The data strips of the data stripes of the storage array each include a parity check bit. The parity strip of each stripe includes a plurality of parity check bits, each of which is uniquely associated with one of the data strips of the stripes. The inclusion within each data stripe of parity bits associated with each data strip and the party strip provides a method for identifying a corrupted or degraded data condition that occurs as a result of a server failing fails during a write command.

摘要： A bus reset control module associated with a fibre-SCSI bridge manages target resets sent from a fibre bus to one or more SCSI buses to reduce or eliminate unnecessary bus resets of SCSI buses having sequential devices, such as tape storage drives. The bus reset control module accepts target resets from a fibre bus host to intercept the initiation of bus resets and communicates with target devices of the SCSI bus to determine whether the target devices are faulty. The bus reset control module issues bus resets to SCSI buses having a faulty target device but prevents issuance of bus resets to SCSI buses that do not have a faulty target device so that a sequential device interfaced with a SCSI bus is not subject to a bus reset if all devices associated with the SCSI bus are operating properly.

摘要： A system and method is disclosed for failure recovery and communications in a shared storage system. The shared storage system includes at least two host nodes, each of which includes two ports. Each of the ports of each of the nodes is coupled to input ports of a storage enclosure. The input ports of the storage enclosures are in turn coupled to one another to form communications links between each of the host nodes. When the communications links between the host nodes fail, the host nodes are able to pass configuration information to each other by saving configuration information to a central location in a shared storage, such as a dedicated location in one of the storage drives of the storage enclosure that is directly coupled to both host nodes. The host nodes are able to force their peer nodes to read configuration changes before accessing possibly corrupted data from a previous configuration.

摘要： Systems and methods for providing data integrity for stored data are disclosed. A method may include, in connection with the receipt of a read command at a storage resource, reading a data block from the storage resource, the data block including a data field, a data integrity field indicating the integrity the data field, and an encryption indicator field indicating whether the data block is encrypted with a current cryptographic key for the storage resource. The method may further include determining whether the data field is encrypted with the current cryptographic key based at least on the encryption indicator field. The method may additionally include returning at least a portion of the data block in reply to the read command in response to determining that the data field is encrypted with a cryptographic key other than the current cryptographic key.

摘要： Access to backup information, such as at network attached storage compliant with NDMP, is managed by interfacing a backup authentication mechanism with a primary authentication system and responding to requests for backup information according to permissions defined by the primary authentication system. A data management application requests access to backup information with an NDMP MD5 hash and includes a domain name and password for an LDAP or AD authentication through a pluggable authentication module. Access to backup information is provided based upon the permissions associated with the domain of the primary authentication mechanism.

摘要： A method of managing storage device resets in a system using shared storage is provided. A reset instruction is received at a shared storage device from a first node. In response, the storage device is at least partially reset, including aborting one or more queued I/O commands including a first I/O command received from a second node. A reset notification timer is started. If an I/O command is received from the second node during the reset notification timer, in response to receiving the I/O command the second node is notified of the storage device reset such that the second node can determine that the first I/O command was aborted. If no I/O command is received from the second node during the reset notification timer, at the expiration of the timer, the second node is notified of the storage device reset such that the second node can determine that the first I/O command was aborted.
