ABSTRACT:
A hybrid storage system comprising mechanical disk drive means, flash memory means, SDRAM memory means, and SRAM memory means is described. IO processor means and DMA controller means are devised to eliminate host intervention. Multi-tiered caching system and novel data structure for mapping logical address to physical address results in a configurable and scalable high performance computer data storage solution.
