  • Page replacement algorithms for use with solid-state drives
    Patent number: 9703492
    Abstract: A page replacement algorithm is provided. An idle range of memory pages is determined based, at least in part, on indications of references to memory pages in the idle range of memory pages, wherein the idle range of memory pages is a set of one or more memory pages. A first memory page is identified in the idle range of memory page for paging out of memory. The first memory page is identified based, at least in part, on indications of modifications to the memory pages. The first memory page is paged out of memory.

  • Cache Driver Management of Hot Data
    Publication number: 20150277782
    Abstract: A cache driver, a host bus adapter and methods used by them are provided. The method used by the cache driver includes: receiving a first I/O request for accessing data, and sending a second I/O request to a host bus adapter (HBA). The cache driver sends the second I/O request in response to determining that the first I/O request accesses hot data on a HDD. In that case, the second I/O request is a request to the HBA to send a third I/O request to both the HDD and an SSD. The method used by the HBA includes: receiving a second I/O request from a cache driver. The second I/O request is a request to the HBA to send a third I/O request to both a HDD and an SSD. The HBA then sends the third I/O request.
