Abstract
An I/O decoupling system comprising an I/O accelerator coupled between a host interface and a channel interface, wherein the I/O accelerator comprises a host manager, a buffer manager a function manager, and a disk buffer. The host manager is coupled to the host interface to receive a request from a connected host computer. The function manager in response to receiving the request allocates the disk buffer and determines a threshold offset for the buffer while coordinating the movement of data to the disk buffer through the channel interface coupled to the disk buffer.
