CACHING STORAGE ADAPTER ARCHITECTURE

摘要

An interface adapter includes a storage module including non-volatile random access memory (RAM), and a lookup module. The storage module is configured to store metadata in the non-volatile RAM. The metadata identifies data from an external storage device cached in a solid-state storage device. The lookup module is configured to receive a read request. The lookup module is further configured to, based on the metadata and in response to the read request, selectively provide cached data from the solid-state storage device or provide second data retrieved from the external storage device.
