摘要： A write frequency of a non-volatile memory is determined at a fine granularity while suppressing consumption of the volatile memory. When it is determined that a copy of specified data from a specified physical storage area to another physical storage area is to be executed, a controller reads the specified data and specified write frequency information, selects a write destination physical storage area group from a plurality of physical storage area groups based on the specified write frequency information and classification information, selects a write destination physical storage area from the write destination physical storage area group, changes the specified write frequency information, writes the specified data to the write destination physical storage area, writes the changed specified write frequency information to the non-volatile memory, and updates translation information based on the write destination physical storage area group and the write destination physical storage area.

摘要： A data memory device has a command transfer direct memory access (DMA) engine configured to obtain a command that is generated by an external apparatus to give a data transfer instruction from a memory of the external apparatus; obtain specifics of the instruction; store the command in a command buffer; obtain a command number that identifies the command being processed; and activate a transfer list generating DMA engine by transmitting the command number depending on the specifics of the instruction of the command. The transfer list generating DMA engine is configured to: identify, based on the command stored in the command buffer, an address in the memory to be transferred between the external apparatus and the data memory device; and activate the data transfer DMA engine by transmitting the address to the data transfer DMA engine which then transfers the data to/from the memory based on the received address.

摘要： A storage device relating to one aspect of the present invention has a storage controller and multiple memory devices. The memory devices manage capacity equivalent to the size of a memory space provided to the storage controller among regions of a non-volatile storage medium as logical capacity and manage the remaining regions as reserve capacity. When a device controller determines that a portion of the memory regions in the non-volatile storage medium is in an unusable state, the device controller notifies the storage controller of the size of the memory regions in the unusable state. On the basis of a policy set by the memory device, the storage controller determines the reduction amount of the logical capacity and the reserve capacity and notifies the memory device of the determined reduction amount of the logical capacity.

摘要： A data transfer device that transfers data to a memory according to an instruction from a processor via a bus through which a response indicating completion of data writing in the memory is not sent back, comprises an inter-memory data transfer control unit including an operation start trigger receiving unit, a parameter acquiring unit, a read unit, and a write unit. When the write unit detects switching of a write destination memory, the write unit confirms write completion as to the memory by a procedure different from writing. When a data transfer instructed by the processor is completed, the write unit confirms write completion as to the write destination memory at the end of the data transfer by the procedure different from writing. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of the write completion.

摘要： A storage subsystem constituting a pool using storage media having rewrite life and providing a logical volume having a virtual capacity to a host, wherein the storage subsystem monitors whether shortage of a remaining rewrite life of the capacity pool will occur or not within an operation period of the storage subsystem, and when it is determined that shortage of the remaining rewrite life will occur, the subsystem converts the rewrite life required to cover the shortage into drive capacity and indicates the same, or indicates the same by reducing an existing pool capacity, and requests maintenance of the subsystem. A maintenance method is provided, wherein elongation of life is executed by adding a capacity to the pool at the time of indication, and as for addition of capacity other than the elongation of life described above, a maintenance fee is charged.
