摘要： A storage area network (SAN)-attached storage system architecture is disclosed. The storage system provides strongly consistent distributed storage communication protocol semantics, such as SCSI target semantics. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes mechanisms to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.

摘要： A method and apparatus for replicating a data container of a source storage server at the logical level in an unordered stream of individual data units are described. In certain embodiments, the replication operations can be performed without regard to the differences in geometry of physical persistent storage of the source and destination storage servers and without regard to the differences in data container format of the source and destination storage servers. An initial replication operation of the source data container is performed by transferring the data objects within the source data container to a replica data container in the destination storage server as an unordered stream of individual data units while preserving data object identifiers of the source data objects. Afterwards, incremental replication operations can be performed to capture modifications to the source data container over time after the initial replication operation.

摘要： A replication operation service migrates data from a source volume having a source file system type to a destination volume having a destination file system type, where the source file system type may be different from the destination file system type. The replication operation is completed without interrupting the operations of a client device in the system. A stable copy of the source file system is generated on the source volume. A file system agnostic representation of a portion of the data in the source volume is generated from the stable copy. The representation is transmitted to the destination volume where it is converted to conform to the destination file system type.

摘要： The invention is a system and method for establishing a communication connection between two programs, each running on multiple processors of a distributed or shared memory parallel computer, or on multiple computers in a cluster of workstations or a set of network connected workstations. The invention includes all protocols that require one of the two programs that wish to communicate to actively initiate the communication session, while the other program passively accepts such direct communication session initiations. No task of the active program of the connection will attempt to communicate with tasks of the passive program until after it has been notified that all passive program tasks are prepared to receive messages, and that all other active program tasks are prepare to receive messages from the passive programs tasks, and vice versa. Further, the tasks of the passive program are free running during establishment of the connection; while the active program tasks are free to run provided that they do not attempt to communicate with the second program. Another aspect of the invention provides a secondary indirect communication channel mediated by as resource manager separate from the active and passive programs.

摘要： A method for storing redundant information in an array of data storage devices such that data is protected against two simultaneous storage device failures. The method assigns each data block to two different parity sets, each protected by a different parity block. The protected data blocks and the parity block each reside on a different data storage device.

摘要： A protocol for achieving atomic multicast in a parallel or distributed computing environment. The protocol guarantees concurrency atomicity with a maximum of m-1 message passes among the m server nodes of the system. Under one embodiment of the protocol, an access component message is transferred to the server nodes storing data to be accessed. The first server node of the plurality generates a token to be passed among the accessed nodes. A node can not process its request until it receives the token. A node may pass the token immediately upon ensuring that it is the current expected token.
