In general, embodiments of the present invention provide a disk an I/O layer architecture having a customized block-level device driver. In a typical embodiment, the architecture described herein comprises a file system layer being configured to handle user data; a buffer cache layer, adjacent the file system layer, the buffer cache layer being configured to handle page data; a block device driver layer adjacent the buffer cache layer, the block device driver layer being configured to handle block data, and the block device driver layer comprising an I/O scheduler layer and a device driver layer; and a storage unit layer adjacent the block device driver layer, the storage unit layer being configured to hand command data. Moreover, the storage unit layer can comprise a set (e.g., at least one) of semiconductor storage device (SSD) memory units, and the I/O scheduler layer can be configured to handle memory-based devices (e.g. a flash SSD memory device, a dynamic random access memory (DRAM) SSD memory device, etc.). |
