ABSTRACT:
In one embodiment, a direct memory access (DMA) disk controller used in hardware-assisted data transfer operations includes command receiving logic to receive a data transfer command issued by a processor. The data transfer command identifies one or more locations in memory and multiple distinct regions on one or more disks accessible to the DMA disk controller. The DMA disk controller further includes data manipulation logic to transfer data between the memory locations and the distinct regions on the disks according to the data transfer command.
