    摘要: Volume configuration data management systems and methods are described. A logical volume provider maintains an epoch number on each of the extents comprising a volume. Upon each change in the configuration of the volume, the epoch number on each of the currently online extents is updated. When a volume is discovered and a request is made to bring the volume online, the logical volume provider can compare the epoch numbers on the extents to determine if the volume data is consistent across each of the extents, or if an extent contains stale data due to a transitory outage.

    摘要: Systems and methods for creating and maintaining a stacked volume using one more volumes or extents of a storage subsystem is disclosed. The systems and methods define a hierarchy of operations and components that process operations. The hierarchy includes plex operations for an entire volume, mapping operations that concatenate volumes and/or extents, plex operations for a volume or extent that is a sub-component of a stacked volume. The hierarchy also includes striping operations that create and maintain storage volume stripes comprising sub-volumes and/or extents. In addition, the hierarchy includes configuration operations that operate directly on a storage volume through a hardware or software volume provider. Together, the hierarchy defined allows a flexible, extensible mechanism to build stacked volumes that provide for increase performance, fault tolerance, and/or aggregate volume size, while elimination volume combinations that can cause performance problems.

    摘要: A storage management system in which a plurality of volume providers maps logical storage volumes onto one or more storage devices within a stand-alone computer or within a storage network. A common volume manager executing on a computer within the storage network selectively communicates commands to one or more of the volume providers in order to control the storage devices. The inventive storage management system seamlessly integrates management of the vendor-specific volume providers. The common volume manager provides a common application programming interface (API) by which applications are able to control and monitor hardware and software volume providers without requiring detailed knowledge of the volume providers or the underlying storage devices. The common volume manager aggregates response information from the volume providers and communicates the aggregated information to the software application that issued the storage management request. The interface is extensible so as to support provider-specific storage management requests and conforms to a component object-model (COM) interface.

    摘要: A storage management system in which a volume provider incorporates an application programming interface (API) for receiving storage access information that characterizes high-level input/output (I/O) attributes of the storage volume such as intended access patterns, a desired level of fault handling and optimization preferences. The volume provider and the underlying storage devices conform to the specified attributes as best as possible and resolve any conflicts with the communicated attributes. The volume providers monitor the storage volumes and may reconfigure the storage volumes in order to accomplish the desired attributes.

    摘要: The invention provides a method and system for arbitrating for ownership of a logical quorum resource, such as a logical quorum volume, comprising one or more physical quorum resources so as to form a storage network having a plurality of storage devices. Arbitration and volume management responsibilities are cleanly divided between cluster management software and volume management software. The cluster management software handles the arbitration process without knowing the details of how the logical quorum resource is formed. The volume management software handles the formation and management of the logical quorum volume without having details of the arbitration process.
