摘要： Storing recovery data includes providing chunks of data to a remote destination, where each chunk of data represents data written before a first time and after a second time and where the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks, providing synchronous data to a local destination, and providing an indicator to the local destination in connection with creation of a new chunk of data for storage at the remote destination. The local destination may maintain a plurality of maps, where each of the maps associates synchronous data being provided thereto with a specific chunk of data. In response to receiving an indicator in connection with creation of a new chunk of data, the local destination may point to a new map. There may be two maps or more than two maps.

摘要： A system for controlling the pacing of host data writes in response to changing system conditions allows for the use of variably controlled delays that facilitate asynchronous replication with bounded lag and smooth steady-state performance. Adding delay to the writes slows down the host and dampens activity spikes. A first storage device receives a write request, transmits data to a second storage device, and acknowledges the write request. An amount of additional write response time is controlled between when the write request is received and when the write request is acknowledged by the first storage device, where the amount of additional write response time is controlled according to system parameters including an amount of lag time between when the write request is received and when the write request is committed at the second storage device.

摘要： A mechanism to support remote mirroring of storage devices by data storage systems in a one-to-many switched environment. Each data storage system includes a disk director that is adapted to control at least one device group that is supported in a mirrored configuration with a corresponding device group controlled by one of the other data storage systems. For each device group and corresponding device group, there are first ports associated with the device group and second ports associated with the corresponding device group. A switch element is adapted to connect one of the first ports to at least one of the second ports so that data may be exchanged between the ports for each device group and corresponding device group. The disk director selects which first port is to be connected to which second port via the switch element in the establishment of a logical link. Thus, each port connected to the switch is capable of achieving multiple connections to multiple destinations for increased connectivity, redundancy and performance (load balance) without additional hardware.

摘要： Using a local storage device to read desired data stored on a remote storage device that receives chunks of data from the local storage device includes, if the desired data is entirely in a cache of the local storage device, the local storage device returning the data from the cache and, if the desired data is not entirely in a cache of the local storage device, reading data from the remote storage device to the local storage device and the local storage device merging the data from the remote storage device with data from the local storage device at the local storage device. Using a local storage device to read desired data stored on a remote storage device that receives chunks of data from the local storage device may also include, prior to reading data from the remote storage device to the local storage device, creating a temporary storage area at the local storage device if there is data from the local storage device that is to be read. The temporary storage area may be a scratch slot.

摘要： Continuous backup from a local storage device to a remote storage device includes subdividing the local storage device into subsections, providing a time indicator that is modified periodically, and, in response to a request to write new data to a particular subsection of the local storage device at a particular time, maintaining at the remote storage device data being overwritten by the new data according to the particular subsection and according to a value of the indicator at the particular time. Providing continuous backup from a local storage device to a remote storage device may also include restoring the local storage device to a state thereof at a particular point in time by writing the maintained data to the remote storage device and transferring the data from the remote storage device to the local storage device.

摘要： A data storage system capable of performing remote data services (e.g., data mirroring) over an IP network using native connections to the IP network is described. The data storage system employs an architecture that manages the remote data services and the native connections to the IP network in a way that isolates the remote data services application software from the TCP/IP and lower level network processing.

摘要： A method for scanning a message-list accessible to a plurality of processors includes retrieving, from a cache associated with a scanning processor from the plurality of processors, information identifying a starting message-slot. This information is then used to begin a scan of the message-list at that starting message-slot. The information indicating the starting message-slot is obtained by identifying, in the message-list, a message-slot containing a message intended for a recipient processor from the plurality of processors and obtaining, from the identified message-slot, information indicative of a location of a succeeding message-slot in the message-list. This information is then cached, for retrieval during a subsequent scan of the message-list.
