Abstract
Official abstract text for this publication.
An information processing apparatus includes a controller. The controller performs a transfer source information generation process for generating transfer source information upon reception of an offload data transfer instruction from a host computer. The controller performs a reserved state setting process for setting, when an instruction to release a release area is received, an overlapping area to a reserved state so as to reserve release of the overlapping area, after issuing a completion response for the release instruction. The controller performs a pending state determination process for determining a pending state in which data transfer using the transfer information might be executed. The controller performs an area release process for releasing the overlapping area which is set to the reserved state and thus is reserved to be released, when the pending state is cancelled.
First claim
Opening claim text (preview).
What is claimed is: 1. An information processing apparatus comprising: a memory configured to store a received offload data transfer instruction; and one or more processors configured to perform a procedure including: generating transfer source information regarding a transfer source area in accordance with the offload data transfer instruction, setting, when a release instruction to release an area overlapping the transfer source area is received, the area to a reserved sta…
