摘要： Efficient communication between storage controllers can be performed. A storage system includes one or more backend switches that connect a first processor, a second processor, and one or more storage devices to each other. Each backend switch identifies a destination of a frame by referring to the frame received from the first processor. In a case where the destination of the frame is the second processor, each backend switch translates a first address, included in the frame, for specifying a location on the second memory in an address space of the first processor, into a second address for specifying the location on the second memory in an address space of the second processor, and transfers the frame including the second address to the second storage controller.

摘要： A storage system according to the present invention has a plurality of flash packages equipped with a deduplication function. When a storage controller transmits a write data and a feature value of write data to a flash package, the flash package compares contents of the write data with data having a same feature value as the feature value of the write data. As a result of the comparison, if there is no corresponding data, the write data is stored in the flash memory, but if there is a corresponding data, the new data will not be stored. Thus, a greater number of data can be stored in the flash memory while preventing deterioration of performance.

摘要： An information system according to one embodiment of this invention includes a first computer which is an SDS (Software Defined Storage) having a virtualization function and a second computer which is an SDS. The first computer can provide a logical volume using a volume in the second computer as a storage region by the virtualization function. When the information system receives a direction to install a storage control program to the second computer, the information system specifies the logical volume using the volume of the second computer as the storage region among logical volumes in the first computer, and then moves data stored in the volume of the second computer used by the specified logical volume as the storage region to a storage device in the first computer. Thereafter, the storage control program is installed in the second computer.

摘要： In a computer system having a storage controller that receives a read request or a write request, a processor is configured to send to an interface device either a read-support indication, which is an indication to execute either all or a portion of read processing for read-data of the read request, or a write-support indication, which is an indication for either all or a portion of write processing for write-data of the write request. Then, the interface device, in accordance with either the read-support indication or the write-support indication, is configured to execute either all or a portion of the read processing for the read-data, or all or a portion of the write processing for the write-data, and to send to a host computer either a first response to the effect that the read processing has been completed, or a second response that the write processing has been completed.

摘要： It is provided a storage system, comprising a storage device for storing data and at least one controller for controlling reading/writing of the data from/to the storage device. The at least one controller each includes a first cache memory for temporarily storing the data read from the storage device by file access, and a second cache memory for temporarily storing the data to be read/written from/to the storage device by block access. The processor reads the requested data from the storage device in the case where data requested by a file read request received from a host computer is not stored in the first cache memory, stores the data read from the storage device in the first cache memory without storing the data in the second cache memory, and transfers the data stored in the first cache memory to the host computer that has issued the file read request.

摘要： A system comprising a plurality of storage systems, which uses storage devices of multiple levels of reliability. The reliability as a whole system is increased by keeping the error code for the relatively low reliability storage disks in the relatively high reliability storage system. The error code is calculated using hash functions and the value is used to compare with the hash value of the data read from the relatively low reliability storage disks.
