Abstract: Various embodiments of the invention relate to an apparatus and a method of managing a snapshot storage pool (SSP) associated with a storage unit of a distributed data storage system. One apparatus includes a logic module and a processor. The logic module is adapted to provide a threshold corresponding to a ratio between a current amount of storage resources used for storing snapshots in the SSP and a total storage capacity defined for the SSP. The processor is adapted to trigger an action that may be effective for managing the SSP in response to the amount of storage resources used for storing snapshots in the SSP crossing the threshold.

Abstract: Storage system(s) for providing storing data in physical storage in a recurring manner, method(s) of operating thereof, and corresponding computer program product(s). For example, a possible method can include for each recurrence: generating a snapshot of at least one logical volume; destaging all data corresponding to the snapshot which was accommodated in the cache memory prior to a time of generating the snapshot and which was dirty at the time of generating said snapshot, thus giving rise to destaged data group; and after the destaged data group has been successfully destaged, registering an indication that the snapshot is associated with an order preservation consistency condition for the at least one logical volume, thus giving rise to a consistency snapshot.

Abstract: A method for migrating data to a mass storage system, including receiving an incoming data partition for storage in the mass storage system and allocating logical storage for the incoming data partition in the mass storage system. The method further includes making a determination that the incoming data partition includes only zero data, and, in response to the determination, inhibiting physical storage of the incoming data partition in the mass storage system while maintaining the allocated logical storage for the incoming data partition.

Abstract: A method is disclosed for operating a data storage system having one or more network interfaces and a plurality of data storage nodes configured to provide redundant storage locations. The method includes storing a set of node partitions on a given storage node of the plurality of data storage nodes. The method also includes, following a recovery by the given storage node from a malfunction, making a determination for a node partition in the set whether the node partition is current or noncurrent, and processing the node partition according to the determination.

Abstract: A method for operating a storage system, consisting of performing an allocation of respective partitions of a physical storage resource of the storage system to respective hosts of the storage system. The method also includes changing the allocation while permitting the respective hosts of the storage system to access the physical storage resource.

Abstract: According to certain embodiments there is provided a system and method which enables clients to automatically generate client CLI response-objects directed for reading new unfamiliar server CLI response-objects which are received from servers without the need to write or obtain new code for each new server response-object.

Abstract: A method for storing data blocks, including forming the data blocks into groups comprising N·M data blocks, where N and M are different positive integers. For every group, the N·M data blocks are assigned to correspond to elements of an array comprising N rows and M columns. A respective parity block is calculated for each of the N rows and M columns, to form (N+M) parity blocks. The resulting (N+M) parity blocks and N·M data blocks are stored in respective storage devices.

Abstract: A method for creating logical volume snapshots in a data storage system, including receiving a first write command to write first data to a partition of a logical volume, generating a first partition descriptor record (PDR), and storing the first data at a first physical location associated with the first PDR. A snapshot command is then received to form a snapshot of the logical volume, after which a second write command is received to write second data to the partition. In response to the second write command, a second PDR is generated and the second data is stored at a second physical location associated with the second PDR. A pointer between the first PDR and the second PDR is generated. In response to a read command indicating a number of a desired snapshot of the logical volume, the first PDR is accessed using the pointer.

Abstract: Disclosed is a system and method from mirroring data from a data storage server/system. A mirroring module on a primary mirror server/system may forward one or more data packets received from the data storage server/system to a secondary mirror server/system. The one or more packets maybe received over a synchronous data link and forwarded over an asynchronous data link.
