Abstract
Systems and methods presented herein provide for simulated NVDRAM operations. In a host system, a host memory is sectioned into pages. An HBA in the host system comprises a DRAM and an SSD for cache operations. The DRAM and the SSD are sectioned into pages and mapped to pages of the host memory. The SSD is further sectioned into regions comprising one or more pages of the SSD. AnHBA driver is operable to load a page of data from the SSD into a page of the DRAM when directed by a host processor, to determine that the page of the DRAM is occupied with other data, to determine a priority of the region of the page of other data occupying the page of the DRAM, and to flush the other data from the DRAM to the SSD based on the determined priority.
