Publication number: 20230273586Abstract: A controller according to an embodiment, to which an input/output device is connected, includes hardware processors. Each of the hardware processors divides data requested to be output into a size being less than or equal to an access division size threshold by making reference to a division table to update the access request data. The dividing of the data is performed in a case when a size of the data requested to be output is greater than the access division size threshold corresponding to an access waiting time in a current state. The division table indicates a correspondence relationship between an access waiting time and an access division size threshold. The access waiting time is a waiting time to access the input/output device. The access division size threshold is a threshold of a data size for determining whether to divide data requested to be output.Type: ApplicationFiled: June 8, 2021Publication date: August 31, 2023Applicant: TOSHIBA INFRASTRUCTURE SYSTEMS & SOLUTIONS CORPORATIONInventors: Katsutoshi NAKAGAWA, Yuta YAMADA
