发明名称 Storage system and data transfer control method
摘要 It is provided a storage system for inputting and outputting data in accordance with a request from a host computer, comprising: at least one processor for processing data requested to be input or output; a plurality of transfer controllers for transferring data between memories in the storage system; and at least one transfer sequencer for requesting a data transfer to the plurality of transfer controllers in accordance with an instruction from the processor. The processor transmits a series of data transfer requests to the at least one transfer sequencer. The at least one transfer sequencer requests a data transfer to each of the plurality of transfer controllers based on the series of data transfer requests. The each transfer controller transfers data between the memories in accordance with an instruction from the at least one transfer sequencer.

主权项 1. A storage system for inputting and outputting data in accordance with a request from a host computer, comprising: at least one processor configured to process data requested to be input or output; a plurality of transfer controllers configured to transfer data between memories in the storage system; and at least one transfer sequencer configured to request a data transfer to the plurality of transfer controllers in accordance with an instruction from the processor; wherein: the processor is configured to transmit a series of data transfer requests to the at least one transfer sequencer; the at least one transfer sequencer is configured to request a data transfer to each of the plurality of transfer controllers based on the series of data transfer requests; and each transfer controller is configured to transfer data between the memories in accordance with an instruction from the at least one transfer sequencer, wherein a data transfer request includes an address where DMA control parameters are stored, and wherein DMA control parameters include address of a transfer source, address of a transfer destination, length of data to be transferred, transfer path, protection code, and end status storage address.
