Abstract: A field-upgradeable database that is separable from system software contains information about mass storage devices that may be present in a storage array. When an uninitialized device is detected in the array, the field-upgradeable database is consulted to discover which non-standard functions the device supports, and one of the non-standard functions is activated. Software and systems using the field-upgradeable database in a storage server configuration are also described and claimed.

Abstract: A filesystem can be converted to a different version by creating a new data structure according to a new format of the different version and transforming the data from the filesystem to the new data structure. Transforming the data can include changing the format of the data in the filesystem to be compatible with the new data structure format. The data may be incorporated into the new data structure by copying the data, or creating indirect reference mechanisms to point to the original data.

Abstract: In a write-anywhere filesystem, a write-in-place property allows the write-anywhere filesystem to selectively perform write-in-place processing for write allocation to selected data blocks. The filesystem stores a data block in a storage, and references the data block with both physical and virtual or logical block number references. The block number references allow the filesystem to manage storage of the data blocks through indirection. The data block may be modified, which generates an updated data block in memory having the new data. The filesystem performs write allocation to store the updated data block to the storage. Write-in-place within the write-anywhere filesystem allows the write-anywhere filesystem to write the data block to the same physical location and thus maintain the same physical block number reference while modifying the virtual block number reference.

Abstract translation: 在随处写入文件系统中，就地写入属性允许随处写入文件系统选择性地执行写入就地处理，以写入分配给选定数据块。 文件系统将数据块存储在存储器中，并使用物理和虚拟或逻辑块号引用来引用数据块。 块号引用允许文件系统通过间接方式管理数据块的存储。 数据块可以被修改，其在存储器中生成具有新数据的更新数据块。 文件系统执行写入分配以将更新的数据块存储到存储器。 随时随地写入文件系统内的写入允许随处写入文件系统将数据块写入相同的物理位置，从而在修改虚拟块号码引用时保持相同的物理块号码引用。

Abstract: A method in a storage system reads blocks having both physical addresses and logical addresses in the storage system from a first set of locations in non-volatile storage to a cache memory and determines the level of data fragmentation in the non-volatile storage. If the level of data fragmentation exceeds a threshold level, the cache memory is marked and the blocks are written to physically sequential locations with new physical addresses in the non-volatile storage at a data consistency point without changing the logical addresses of the blocks.

Abstract: A system and method for managing data deduplication of a storage system utilizing persistent consistency point images (PCPIs). Once a target PCPI of a data transfer is generated, a backup management module of the storage system alerts a data deduplication module to begin deduplication of the data contained within the target PCPI. Once the deduplication procedure has been completed, the active file system of the storage system has been deduplicated, however, the target PCPI remains un-deduplicated. In response, the backup management module generates and exports a revised target PCPI. The previous target PCPI may then be deleted, thereby transitioning the exported PCPI's image of the state of the file system to a deduplicated state.

Abstract: A system and method for management of jobs in the cluster environment is provided. Each node a cluster executes a job manager that interfaces with a replicated data- base to enable cluster wide management of jobs within the cluster. Jobs are queued in the replicated database and retrieved by a job manager for execution. Each job manager ensures that jobs are processed through completion or, failing that, are re-queued on another storage system for execution.

Abstract: An electronic device includes a printed circuit board having a wall deposited directly on a board serving as a base for a printed circuit. As the board is constructed, the wall is deposited on the board for controlling airflow. The wall controls airflow across the board and around components mounted to the board. The wall may be utilized for controlling airflow in combination with a second printed circuit board positioned adjacent to the first printed circuit board. The wall may be utilized for controlling various types of airflow, including airflow from sources including fans and convection, and from geometries including horizontal and vertical mounting geometries. The silicon wall may be utilized for preventing heat airflow generated by heat radiated from one component from impinging upon another component.

Abstract: Multiple domains are created for processes of a storage server. The processes are capable of execution on a plurality of processors in the storage server. The domains include a first domain, which includes multiple threads that can execute processes in the first domain in parallel, to service data access requests. A data set managed by the storage server is logically divided into multiple subsets, and each of the subsets is assigned to exactly one of the threads in the first domain, for processing of data access requests directed to the data set.

Abstract: A system and method for the failover of iSCSI target portal groups (TPGs) is provided. Each network portal within a storage system is associated with a network portal data structure identifying a destination storage system in the event of failover/takeover operation. A management module ensures that all network portals associated with a target portal group have the same destination as a failover storage system. During a failover operation, all network portals within a TPG failover to the same destination storage system.
