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. The DRAM and the SSD are also sectioned into pages and mapped to pages of the host memory. A host processor is operable to generate Input/Output (I/O) requests. An HBA driver is operable to process the I/O requests. The HBA driver is also operable to detect when the pages of the DRAM are accessed, to determine a rate of page reclamation based on the detection, and to reclaim pages of data in the DRAM by moving pages of data from the DRAM into the pages of the SSD based on the determined rate of page reclamation.
