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： A SAN-based cluster backup system and method are provided. The system and method are automated, do not use a LAN for backup data, and are made aware of application failover events. The system and method are composed of two main components: a backup service, and a primary coordinator. The backup service performs the backup of the applications that are hosted on a particular node. The backup service periodically checkpoints the state of the backup job and communicates the status to the primary coordinator. The primary coordinator controls all backup operations in the cluster. The user submits backup jobs for the applications through the primary coordinator. If a node fails during a backup operation, the primary coordinator can ensure that the failed backup job can be resumed from the last checkpoint on the failed-over node. In this way, repetitive backups can be avoided, thereby increasing efficiency.

摘要： According to various illustrative embodiments of the present invention, a method for adaptive cluster input/output control includes starting a nonessential input/output operation using a first controller in a first node of a cluster, informing at least a second controller in a second node of the cluster about starting the nonessential input/output operation, and increasing the nonessential input/output operation by a predetermined utilization percentage. The method also includes waiting for a predetermined amount of time, determining whether the nonessential input/output operation has been completed, and determining whether the at least the second controller in the second node has substantially decreased performance. The method also includes decreasing the nonessential input/output operation by the predetermined utilization percentage if the nonessential input/output operation utilization percentage is greater than the predetermined utilization percentage and if the at least the second controller in the second node has substantially decreased performance, and informing the at least the second controller in the second node of the cluster about the completion of the nonessential input/output operation if the nonessential input/output operation has been completed.
