摘要： Described is a method and means in which data and parity blocks forming parity groups together with spare blocks are distributed over array block locations according to at least one combinatorial design, each group having N data and P parity blocks. The combinatorial designs yield uniform or balanced loading thereby minimizing the number of accesses to reconstruct missing data and parity blocks and their copyback into spare block locations, and, minimize the number of accesses to the reconstructed data referenced subsequent to its copyback. Distributions of the spare block capacity of one or two DASDs are shown over single and multiple arrays and shared among multiple arrays. Parity block distribution although ancillary to spare distribution enhances throughput and reduces the number of accesses for rebuild etc.

摘要： La mémoire (100) d'une unité à disques de la présente invention utilise une grande pluralité de petites unités à disques de facteur de forme (130) pour mettre en oeuvre une mémoire d'unités à disques peu coûteuse, de haute performance et haute fiabilité qui émule le format et la capacité de grandes unités à disques de facteur de forme. La pluralité des unités à disques (130) sont interconnectables (121) de manière commutable pour former des groupes de redondance de N+M unités à disques connectées en parallèle pour y stocker des données. Les N+M unités à disques sont utilisées pour stocker les N segments de chaque mot de données plus les M segments de redondance. De plus, un groupe de R unités à disques de sauvegarde (130) est maintenu pour remplacer une unité à disques par une unité à disques de remplacement dans un groupe de redondances qui est défaillant pendant le fonctionnement. Le nombre N de segments de données dans chaque groupe de redondances de données peut varier dans toute la mémoire de l'unité à disques de manière à correspondre aux caractéristiques des données d'entrée ou paramètres de fonctionnement dans la mémoire de l'unité à disques. En outre, un groupe de U unités à disques non affectées (130) peut être maintenu comme réserve d'unités à disques pouvant être mises en route si besoin est et affecté soit à un groupe de redondances soit au groupe d'unités à disques de sauvegarde.

摘要： A method for data storage includes sending write commands to a first storage node (28A), for storing data in a data volume (56A) on the first storage node. In response to a decision to create a copy (56B) of the data volume on a second storage node (28B), (i) the write commands are sent both to the first storage node and to the second storage node, and (ii) a snapshot of the data volume is created and sent from the first storage node to the second storage node. The copy of the data volume is created by the second storage node based on the snapshot and on one or more of the write commands received at the second storage node.

摘要： A real time database system configured to store database content with a plurality of data sets, the database content being partitioned in different partitions. The system comprises a plurality of master databases, each master database containing a partition of the database content, each partition being provided on a different physical storage unit and at least one replica database, each replica database containing subpartitions of the partitions stored in master databases. The system further comprises at least one distributor configured to route a request for a data set to the master database, where the data set to which the request refers to, is provided, and divide each partition into several subpartitions. Additionally, the system comprises at least one replicator, configured to generate a replica of each subpartition, and configured to store each replica on a replica database.

摘要： Systems and methods of implementing server architectures that can facilitate the servicing of memory components in computer systems. The systems and methods employ nonvolatile memory/storage modules that include nonvolatile memory (NVM) that can be used for system memory and mass storage, as well as firmware memory. The respective NVM/storage modules can be received in front or rear-loading bays of the computer systems. The systems and methods further employ single, dual, or quad socket processors, in which each processor is communicably coupled to at least some of the NVM/storage modules disposed in the front or rear-loading bays by one or more memory and/or input/output (I/O) channels. By employing NVM/storage modules that can be received in front or rear-loading bays of computer systems, the systems and methods provide memory component serviceability heretofore unachievable in computer systems implementing conventional server architectures.

摘要： Embodiments of the present invention provide a memory data migration method and apparatus, and a computer, to migrate memory data that is in the computer. After acquiring a first trigger instruction, an operating system of the computer can suspend a task that is being executed, to execute memory data migration, determine a source memory card of to-be-migrated memory data, determine a backup memory card for the source memory card, and instruct a memory controller of the source memory card to perform the memory data migration, so that the memory controller of the source memory card reads memory data of the source memory card according to an instruction of the operating system, and writes the read memory data of the source memory card into the backup memory card. Therefore, the memory data of the source memory card can be migrated without powering off of the computer, thereby implementing online maintenance on a faulty memory card and resolving a problem in the prior art that a faulty memory card can be replaced or maintained only after an entire computer is powered off.
