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.

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： 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 system and method is disclosed for the automatic assignment, or reassignment, of shared storage resources to blade computers in a blade server environment. A chassis manager is implemented as a processing entity on the mid-plane of a blade server chassis to provide, independently or in conjunction with other systems and/or attached storage devices, management of shared storage resources. Management of these resources includes, but is not limited to, creation of logical units, assignment of logical units to predetermined blade server chassis slots, and deletion of logical units. Host-based software is not required to assign shared resources to a computer blade, only its presence in a predetermined slot of a blade server chassis. Logical unit numbers (LUNs) are assigned by the chassis manager based on blade server slot IDs while host-unique identifiers, such as world wide names (WWNs) are used by one or more shared storage controllers for internal LUN addressing.

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.
