摘要： A system using consistent virtual addresses to communicate in cooperative multi-layer virtualization environments includes a volume server, one or more physical storage devices, a front-end layer and a back-end layer of virtualization participants. The volume server may be configured to aggregate storage in the one or more physical storage devices into a logical volume, and to provide configuration information on the logical volume to a front-end virtualization participant and to a back-end virtualization participant. The front-end virtualization participant may be configured to send a storage request including a target virtual address identifying a block of the logical volume to the back-end virtualization participant. The back-end virtualization participant may be configured to use the configuration information to identify a physical data block at a physical storage device corresponding to the target virtual address, and to perform a physical I/O operation on the physical data block.

摘要： Disclosed is a method and apparatus for replicating a data volume using a network appliance. In one embodiment, a first node transmits a first write-data transaction to a first data storage system and to the network appliance. A second node transmits a second write-data transaction to the first data storage device and to the network appliance. The network appliance transmits the first and second write-data transactions to a third node via a communication link for updating a replica of a data volume. The data volume is stored in the first data storage system and is updated with first and second data contained in the first and second write-data transactions, respectively. The replica of the data volume is stored in a second data storage system and is updated with the first and second data.

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.
摘要翻译：从计算机系统接收到第一个读取请求。响应于接收到第一读取请求，数据卷的一个镜像的数据被返回到计算机系统。计算机系统可以检查返回的数据以确定其是否被破坏。如果损坏，计算机系统会发送相同数据的第二个读取请求。不是返回存储在一个镜像中的相同的损坏数据，而是从数据卷的备用镜像返回所请求数据的副本。

摘要： In a system in which read data tracking and caching is used to recover from data corruption, a first request to read data from a primary data mirror is received from a computer system. Data is read from the primary data mirror in response to receiving the first request. Additionally data from a mirrored copy of the primary data mirror is read. Data read from the primary data mirror is returned to the computer system. Data read from the mirrored copy is stored into a memory device. If a second request is received from the computer system to read the same data of the first request, data stored in the memory device may be returned in response thereto.

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.
