    摘要: In one embodiment, a method is provided that may include determining, at least in part, at an intermediate station one or more locations in storage devices of one or more respective portions of check data and/or other data. The check data may be generated, at least in part, at the intermediate station based at least in part upon the other data. This method also may include determining, at least in part, at the intermediate station, based at least in part upon forwarding information, one or more ports of the intermediate station via which to forward one or more packets. The one or more packets may be generated at the intermediate station based at least in part upon one or more other packets received via one or more other ports of the intermediate station. The other packets may comprise the check data and/or other data.

    摘要: Disclosed herein are methods that may be implemented in a mobile computer system. An exemplary method may include initiating a split of a storage volume of the mobile computer system. The storage volume may comply with a fault tolerant storage technology. Suitable technologies include, but are not limited to, those based on Redundant Array of Independent (or Inexpensive) Disks (RAID). In one aspect, the initiation of the split of the storage volume may be based, at least in part, on power availability. Then, a reduction of a power consuming state of a first storage device of the volume may be initiated.

    摘要: In one embodiment, a method is provided that may include, if a change in configuration of storage occurs during one mode of operation of a device, storing, in the storage, data indicative, at least in part, of resulting configuration of the storage resulting after the change. The device may have a relatively lower power consumption rate while the device is operating in the one mode of operation compared to a relatively higher power consumption rate that the device may have while the device is operating in another mode of operation. Of course, many modifications, variations, and alternatives are possible without departing from this embodiment.

    摘要: Apparatus and systems, as well as methods and articles, may operate to create a log file in a non-volatile data storage medium. The log file may comprise a header record, a trailer record, and at least one partial parity value associated with a stripe in a redundant array of inexpensive disks (RAID) sub-system. The stripe may comprise a first data strip to be updated located on an operational first disk drive, a second data strip located on a failed disk drive, and a stripe parity strip located on an operational disk drive, among others.

    摘要: Provided are a method, system, and program for managing data migration from one data organization type to another. In one embodiment, a migration manager defers writing progress indicators to reduce data write operations during the migration process. In one embodiment, progress indicators are written to configuration areas of disk drives when a condition is met. One example of a condition is the expiration of a time period since the last progress indicator was written. Another example of a condition is an overlap between the destination of a unit of data being migrated and the source of the unit of data. Yet another example is an overlap between the destination of a unit of data and a portion of the data source which has been copied but a progress indicator has not yet been written covering the data source portion.

    摘要: Provided are a method, system, and program for migrating data between storage volumes. A source map is provided indicating blocks of data striped across a first plurality of storage units and a destination map is provided indicating blocks of data striped across a second plurality of storage units, wherein data is migrated from stripes indicated in the source map to corresponding stripes indicated in the destination map. In response to determining that the source stripe and the destination stripe occupy a same physical location on the storage units, the data from a source stripe is written to a copy area and writing the data from the copy area to a corresponding destination stripe.

    摘要: In certain embodiments, a plurality of nodes of a hierarchical data structure are generated, wherein each node of the hierarchical data structure represents a set of at least one locked logical block. A request is received to exclusively access a set of at least one logical block. A determination is made, by traversing at least one node of the hierarchical data structure, whether the set of at least one logical block overlaps sets of at least one locked logical block represented by the plurality of nodes of the hierarchical data structure.

    摘要: Provided are a method, system, and program for managing updates of user data and parity data stored in stripes across a plurality of disk storage units arranged in a data organization type such as a RAID array. In one embodiment, a record of stripes potentially containing inconsistent user and parity data is stored on a disk storage unit. In another aspect, before writing a record of stripes to a disk storage unit, stripe entries for a plurality of write processes is permitted to accumulate. In another aspect, a record of stripes may be written to different disk storage units and a generation number is used to identify the latest record of stripes.
