摘要： Systems and methods which provide for managing multiple minor resources in a storage distribution network are provided. In some embodiments, a system provides for both high availability and disaster recovery functionality at different mirroring locations. Other embodiments may provide for multiple high availability and/or multiple disaster recovery mirror resources. These mirror resources are operated in a heterogeneous manner in the sense that each have its own transport, protocol, and the like, but are configured function cooperatively or as a single minor with respect to minoring a primary node. Embodiments may provide for the minoring and resynchronization of mirrored resources in the event of a communication loss with a particular resource without ceasing the minoring operations to other resources.

摘要： An administrator provisions a virtual disk in a remote storage platform and defines policies for that virtual disk. A virtual machine writes to and reads from the storage platform using any storage protocol. Virtual disk data within a failed storage pool is migrated to different storage pools while still respecting the policies of each virtual disk. Snapshot and revert commands are given for a virtual disk at a particular point in time and overhead is minimal. A virtual disk is cloned utilizing snapshot information and no data need be copied. Any number of Zookeeper clusters are executing in a coordinated fashion within the storage platform, thus increasing overall throughput. A timestamp is generated that guarantees a monotonically increasing counter, even upon a crash of a virtual machine. Any virtual disk has a “hybrid cloud aware” policy in which one replica of the virtual disk is stored in a public cloud.

摘要： According to one embodiment, a shared storage system includes a plurality of host servers, a plurality of storage devices, and a management server. The management server manages each of a plurality of logical units using first address management information, and manages a revision of the first address management information using first revision data. The host servers each hold respective copies of the first address management information and first revision data. When a first host server has requested a first storage device to execute access, based on a copy (second revision data) of the first revision data, the first storage device executes the requested access on condition that the second revision data coincides with revision data notified by the management server.

摘要： A method and system for replication in a noSQL database using a global transaction identifier (GTID) unique to each transaction and stored with an associated operations log. The GTID specifies the applicable primary, the sequence of the transaction, and, optionally, also includes information on whether the transaction was applied to a given primary, and for secondaries whether the transaction was applied to the collections. This method and system provides recovery for a crashed primary, re-integrating the crashed primary as a secondary, and point-in-time recovery, optionally having user-specified parameters from which recovery commences.

摘要： A method for transparently upgrading derived database objects commences upon analysis of the data dictionary definition for an initial derived database object as compared to the data dictionary definition for a patched derived database object, then determining if a regenerated instance of the derived database object would be logically different from the initial derived database object. The determination is based on comparisons of the definitions of the initial derived database objects and patched definitions of respective database objects. The method produces a regenerated instance of the derived database object when a regenerated instance of the patched derived database object would be logically different from the initial derived database object. The method will suppress the production of a regenerated instance when a regenerated instance of the derived database object would not be logically different from the initial derived database object. Once regenerated or suppressed, a post-upgrade software application accesses the regenerated derived database object instance (if regenerated) or the initial derived database object if the regenerated instance was suppressed.
摘要翻译：与用于修补的派生数据库对象的数据字典定义相比较，分析初始派生数据库对象的数据字典定义时，开始透明升级派生数据库对象的方法，然后确定派生数据库对象的再生实例是否将在逻辑上与初始派生数据库对象不同。该确定是基于初始派生数据库对象的定义和各个数据库对象的修补定义的比较。当修补的派生数据库对象的重新生成的实例在逻辑上与初始派生的数据库对象不同时，该方法将生成派生的数据库对象的再生实例。当派生数据库对象的再生实例在逻辑上与初始派生数据库对象不同时，该方法将抑制重新生成的实例的生成。一旦重新生成或被抑制，升级后的软件应用程序会访问重新生成的派生数据库对象实例（如果已重新生成）或初始派生数据库对象（如果重新生成的实例被抑制）。
