摘要： A computer system that implements a method for creating a virtual snapshot of a first storage object. A first storage object such as a data volume is created, wherein creating the first storage object includes creating a first storage object description. This first storage object description relates the first storage object to underlying first storage objects or first physical memory regions. After creating the first storage object, a virtual copy of the first storage object is created as a second storage object. Creating the second storage object includes creating a second storage object description, wherein the second storage object description relates the second storage object to the first storage object. The first storage object is transmitted to a first computer system, and the second storage object description is transmitted to a second computer system.

摘要： A system and method for data storage in an array. A system includes a client coupled to a storage subsystem. The storage subsystem comprises data storage locations addressable as rows and columns in an array. Each column comprises a separate storage device. Each row includes redundant data. For a given row, a coordinating storage device receives data from the client, coordinates computation and storage of redundant data, and forwards data to other storage devices. In response to receiving data targeted for storage in a given storage location, a non-volatile, temporary storage device that is associated with the separate storage device that includes the given storage location buffers the received data. The coordinating storage device conveys a write completion message to the client in response to detecting that the data has been buffered in the non-volatile, temporary storage devices. At least two storage devices are coordinating storage devices in separate rows.

摘要： A system for host-based virtualization optimizations in storage environments employing off-host virtualization may include a host, one or more physical storage devices, and an off-host virtualizer such as a virtualizing switch. The off-host virtualizer may be configured to aggregate storage within the one or more physical storage devices into a virtual storage device such as a logical volume, and to provide control data for the virtual storage device to the host. The host may be configured to use the control data to perform a function in response to an I/O request from a storage consumer directed at the virtual storage device, and to use a result of the function to coordinate one or more I/O operations corresponding to the I/O request.

摘要： A first read request is received from a computer system. Data from one mirror of a data volume is returned to the computer system in response to receiving the first read request. The computer system may check the returned data to determine whether it is corrupted. If corrupted, the computer system sends a second read request for the same data. Rather than returning the same corrupted data stored in the one mirror, a copy of the requested data is returned from an alternate mirror of the data volume.

摘要： A method, system, computer system, and computer-readable medium for maintaining up-to-date, consistent copies of primary data without the need to replicate modified data when the data were modified as a result of an operation that is not an application-driven write operation captured during replication. Selected storage management operations are performed on the primary and secondary data stores at points in time when the data are the same to ensure that the data stored within the data stores remain consistent. These selected storage management operations include operations that produce modified data stored in the primary data store, where a portion of the modified data are not replicated to a secondary node. Other types of storage management operations are selected to be performed on both the primary and secondary data stores, where the operations do not directly change data in the primary data store, but may affect data stored in the primary data store.

摘要： Various embodiments of systems and methods are disclosed for initially synchronizing redundant data (e.g., a mirror, a replica, or a set of parity information) with an original volume. State information identifies which regions of the original volume are currently valid, and only valid regions of the original volume are used to generate the values of the redundant data during the initial synchronization. For example, if the redundant data is a set of parity information, synchronizing the redundant data involves calculating one or more parity values based on the valid regions of the volume. If the redundant data is a duplicate copy (e.g., a mirror or replica) of the volume, synchronizing the redundant data involves copying the valid regions of the volume to the duplicate copy of the volume. If the original volume includes any invalid regions, unnecessary copying and/or processing for those regions can be avoided during the initial synchronization.
摘要翻译：公开了用于使冗余数据（例如，镜像，副本或一组奇偶校验信息）与原始卷同步的系统和方法的各种实施例。状态信息确定原始卷的哪些区域当前是有效的，并且只有原始卷的有效区域用于在初始同步期间生成冗余数据的值。例如，如果冗余数据是一组奇偶校验信息，则同步冗余数据涉及基于该体积的有效区域来计算一个或多个奇偶校验值。如果冗余数据是卷的重复副本（例如，镜像或副本），则同步冗余数据涉及将卷的有效区域复制到卷的副本。如果原始卷包括任何无效区域，则可以在初始同步期间避免对这些区域的不必要的复制和/或处理。
