摘要： A system and method of retrieving management information in a protocol environment having a maximum retrieval byte size is provided. An example of such a protocol environment is SCSI environment. A retrieval command is sent from an initiator to a target where the retrieval command is capable of retrieving more information than the maximum allowed by the protocol. A target buffer is created at the target in response to the retrieval command and the target buffer is filled with management information associated with the target. The management information may be in the form of mode pages when the method is applied in a SCSI environment. The management information is then sent from the target buffer to the initiator. If all of the management information is not retrieved, a second retrieval command is sent by the initiator to retrieve at least a portion of the unsent management information.

摘要： A method and a system for use in managing data storage is disclosed. Data storage is managed in a data storage system comprising a first and a second storage processor and a plurality of data storage devices arranged in a RAID configuration, the first and the second storage processor having respective caches configured to mirror each other. A write I/O is received in the data storage system, wherein the write I/O is an operation for updating data storage in the data storage system. Stripe layout in the plurality of data storage devices in the data storage system is established. It is determined whether the write I/O is at least one full stripe write in response to receiving the write I/O and establishing stripe layout. The at least one full stripe write bypasses cache and is delivered to the plurality of data storage devices in the data storage system in response to determining the write I/O is at least one full stripe write.

摘要： A method apparatus and computer program product for providing access to host attribute information in a storage area network is disclosed. The storage area network is composed of a plurality of hosts coupled to at least one initiator. Each initiator is coupled to one or more targets and each initiator has an associated identifier. In each host, the identifier of the initiator is related to other host attribute information. The identifier may be, for example, a world wide name. The host attribute information including the identifier is sent from each of the plurality of hosts to the one or more targets and stored in memory of an associated storage array. Either a host or requestor remote from the storage array may request the collected host attribute information from the storage array. A topology of the storage area network may then be formed from the host attribute information of each host.

摘要： Described are techniques for migrating data. A source data storage system includes a source device and a target data storage system includes a target device. A passive path and an active path are provided for a host to access data of a logical device. The host recognizes the passive path and the active path as paths to the logical device. The passive path is between the host and the source data storage system. The active path is between the host and the target data storage system and used in connection with proxying requests directed to the logical device received from the host through the target data storage system while migrating data for the logical device from the source device to the target device. Migrating is controlled by a migration module executing on the target data storage system that copies data from the source device to the target device.
