    摘要: This invention bridges the gap between bare-block messaging for I/O and exchange messaging for inter-task communication by providing a message make service to make exchange messages from bare-block messages during input and a message unmake service to do the opposite during output. This invention also introduces new capabilities for message broadcasting by using broadcast message exchanges and message multicasting and distributed message assembly by using proxy messages.

    摘要: A method begins by a dispersed storage (DS) processing module receiving access requests, processing data set requests and issuing access responses. The method continues by monitoring slice access requests to generate access records by either storing time stamped access records indicating identities of slices requested by a timestamp or by commonality of slice names. The method continues with determining a correlation of two or more slice access based on the access records when a correlation is greater than a correlation threshold and identifying two or more slices for co-location. The method continues when the two or more slices are not co-located by selecting one or more of the two or more slices for migration to a common memory device.

    摘要: An administrator instructs creation of a volume to a virtual storage device and registration of a host port for providing access permission to the volume. The virtual storage device searches a candidate of a physical storage device capable of reaching the host port and a candidate of the target port based on the access permission information, and creates a distributed volume astride the candidate physical storage device. The distributed volume is composed of a plurality of partial volumes, and the partial volumes inherit the functions of the storage device and the access permission information set for the distributed volume. The virtual storage device distributes an access permission to the physical storage device, constitutes the access permission information of the host port and the volume with respect to the candidate target port, and registers the access permission information of the host port and the target port to the SAN switch.

    摘要: A storage system includes: a storage device including a recording medium that stores data and a device controller that executes addition processing involving a change of state of the data with respect to the data; and a storage controller that controls input and output of data for the storage device. The storage controller transmits, to the storage device, determination information that can be utilized by the device controller for determining whether or not to execute the addition processing along with input-output processing relating to input-output target data. The device controller controls execution of the addition processing with respect to the input-output target data based on the determination information transmitted from the storage controller.
