    摘要: A system and method for optimizing lun masking of a storage appliance is provided. Upon login, an initiator data structure containing a lun map is created and associated with each initiator connected to the storage system. When an initiator sends a message directed to a lun associated with the storage system, the storage system maps the lun sent by the initiator to a physical lun associated with the storage system using the lun map. If the lun map contains an appropriate entry, then the lun has been successfully exported and/or masked to the given initiator.

    摘要: A multi-protocol storage appliance serves file and block protocol access to information stored on storage devices in an integrated manner for both network attached storage (NAS) and storage area network (SAN) deployments. A storage operating system of the appliance implements a file system that cooperates with novel virtualization modules to provide a virtualization system that “virtualizes” the storage space provided by the devices. Notably, the file system provides volume management capabilities for use in block-based access to the information stored on the devices. The virtualization system allows the file system to logically organize the information as named file, directory and virtual disk (vdisk) storage objects to thereby provide an integrated NAS and SAN appliance approach to storage by enabling file-based access to the files and directories, while further enabling block-based access to the vdisks.

    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 technique enables efficient access to logical unit numbers (luns) or virtual disks (vdisks) stored on a storage system, such as a multi-protocol storage appliance. The technique allows a grouping of initiators by a “human friendly” logical name that is mapped to a lun or vdisk on the storage appliance. The initiators are clients operating in, e.g., a storage area network (SAN) environment that initiate requests for the vdisk using block-based access protocols, such as the Small Computer Systems Interface (SCSI) protocol encapsulated over TCP/IP (iSCSI) or over fibre channel (FCP). The technique enables access to the vdisk by all initiators that are members of the initiator group (igroup). An igroup is a logical named entity that is assigned to one or more addresses associated with one or more initiators. These addresses may comprise fibre channel (FC) world wide name (WWN) or iSCSI name identifiers (IDs). Therefore, rather than having to specify these IDs when desiring access to a vdisk, an initiator need only specify the human friendly name of the igroup.
