Title: Method for accelerating i/o between user memory and disk using pci memory
Inventor: SOK SONG WOO
IPC: G06F13/28
Filed: 2007-09-28
Abstract: A method for accelerating speed of IO between a user memory and a disk by using a PCI memory is provided to access data at a high speed while a user program manipulates or refers to data by inputting or outputting directly data to or from the user memory. A method for accelerating speed of IO between a user memory and a disk comprises the following several steps. If a user program requests IO with respect to an arbitrary disk(S101), an internet server computing system determines a network storage card to which the disk is connected(S102) and assigns a PCI memory not used in the NS card(S103). The internet server computing system determines whether the IO request of the user program is read or write(S104). In case of the read IO request, the system reads data on a block of the disk, which requests the data IO, to the assigned PCI memory(S105). Then, the system transmits the data of the PCI memory to the user memory by using DMA(Direct Memory Access) of an IO process of the NS card(S106). In case of the write IO request, the system transmits data of the user memory to the assigned PCI memory by using the DMA(S107) and stores the data of the PCI memory at a block of the disk which requests the data IO(S108).
