    摘要: A system and method for clustered failover of storage appliances is provided. In the event of a failover of one storage appliance to a surviving storage appliance, the surviving storage appliance assumes the identity of the failed storage appliance. This assumption of the identifier is accomplished by initializing a Fibre Channel Host Bus Adapter on the surviving storage appliance with the NodeName and PortNames of the failed storage appliance.

    摘要: A system and method enabling transparent access to blocks, such as virtual disks, stored on a storage system using a file-based protocol. The system and method traps in-coming file-based protocol open commands to check for a predetermined modification to the file name. If the system and method detects the predetermined modification, then the virtual disk associated with the file name is exported to the client issuing the open command and the client receives a response from the storage system. The client, in response to receiving the response to the open command, creates a new device instantiation for reading and writing raw data to the virtual disk.

    摘要: A system and method proxies data access commands acrossed a cluster interconnect between storage appliances and a cluster using a file-level protocol. Each storage appliance activates two ports per data access, a local port for data access requests directed to clients of the storage appliance and a proxy port for data access requests directed to the partner storage appliance. Clients utilizing multi-pathing software may send data access requests to either the local port of the storage appliance or the proxy port of the storage appliance. The system and method improves high availability, especially during a loss of connectivity due to non-storage appliance hardware failure.

    摘要: The present invention provides a system and method for inband management of a virtual disk. A novel volume information command, which is a vendor-specific SCSI command, is sent by a client to a storage appliance, in response, generates a data structure containing various path and networking data associated with a vdisk. This data structure is then returned to the requesting client via a SCSI connection. A client may then utilize the returned information for generating snapshots or other data integrity/backup features offered by the storage appliance.

    摘要: A system and method for providing persistent node names is provided. The system and method stores the node name associated with a given storage system in the root volume associated with the storage system. Thus various components of the storage appliance may be modified without changing the node name associated with a given storage system. This enables clients to have a consistent and persistent node name to connect to in a given network environment.
