Abstract: A method and apparatus are disclosed for restoring a virtual disk (vdisk) in a data storage system as the vdisk was at an earlier time. Pointers are maintained to point to data represented by the vdisk. The pointers are saved to persistent storage at the earlier time. The data at the earlier time is maintained on the data storage device. A pointer pointing to data represented by the vdisk at a later time is compared with the pointers saved at the earlier time. If the pointer from the later time matches the pointer saved at the earlier time, keeping the pointer from the later time in the active file system. If the pointer from the later time does not match the pointers saved at the earlier time, copying a set of pointers associated with the pointer saved at the earlier time to the active file system.

Abstract: 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 (320) that cooperates with novel virtualization modules to provide a virtualization system (300) that ~virtualizes~ the storage space provided by the devices. The file system provides volume management capabilities for use in block-based access to the information stored on the devices. The virtualization system (300) allows the file system to logically organize the information as named file (324), directory (326) and virtual disk storage objects (322, 328) 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 virtual disks.

Abstract: A Multi-Pathing Optimization Module (MPOM) interfaces with a client to route a data access request along a most optimal path to a storage system serving data container stored on a striped volume set (SVS). The MPOM constructs and references a Location Data Structure (LDS) containing striping rules associated with the SVS, a list of network elements (N-blades) operatively connected to the client, and a list of disk elements (D- blades) sharing a node of the storage system with the listed N-blades. The MPOM executes a Client_Locate( ) function on a per data access request basis to identify the D- blade serving the volume which will receive the request. When possible, the MPOM routes the data access request directly to the N-blade sharing a node with the identified D-blade, thereby using the most optimal path from the client to the SVS.

Abstract: A logical number (LUN) cloning technique separates data blocks referenced by a writable virtual disk (vdisk) from data blocks referenced only by a backing store to conserve storage resources of a storage system. The LUN cloning technique separates the writable vdisk data blocks from the backing store during periods of reduced processing activity and in a manner that does not interfere with storage service provided by the system.

Abstract: A system and method for reclaims unused space from a thinly provision data container served by a storage system. A host-side agent detects blocks of the data container that may be freed and sends a novel Punch Hole command to the storage system associated with the data container. The storage system allocates the appropriate blocks in response to the Punch Hole command.

Abstract: A system and method proxies data access commands across 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.
