Abstract
A method may use memory efficiently to extend cache. A processor receives a request to write data. The size of the data in the write request is compared to a threshold. When the size of the data exceeds the threshold, the data is stored on a solid state device. Page descriptors for the data on the solid state device are stored in a metadata log, and a reference to a first page descriptor of the page descriptors in the metadata log is stored in a first hash table in memory.
