Abstract:
1. A storage device communicating with a host computer and another storage device through a network, said storage device comprising: an available buffer including a plurality of memory buffers; an in-use buffer including a plurality of memory buffers already allocated as memory buffers dedicated for communications; notification means for giving a notice of an available-buffer size to an external inquirer in response to an inquiry made by the external inquirer; buffer securing means for taking memory buffers having a reserved-buffer size specified in addition to a buffer-reservation target in a request made by an external requester through the network as a request for a buffer reservation out of said available buffer and reserving said taken memory buffers as a reserved buffer for said buffer-reservation target in response to said request for a buffer reservation based on said reserved-buffer size specified in said request; allocation means for allocating said memory buffers of said reserved buffer to said buffer-reservation target to make said allocated memory buffers a part of said in-use buffer in response to a request made by the external requester as a request to start an application; and execution means for executing the application communicating by using said in-use buffer allocated by said allocation means.
