Third, the mvFIFO replacement of FaCE enables efficient and persistent management of the meta data directory for the flash cache and allows more sustainable I/O performance for higher transaction throughput.
Fourth, FaCE takes advantage of the nonvolatility of flash memory to minimize the recovery overhead and accelerate the system restart from a failure. Since most data pages needed during the recovery phase tend to be found in the flash cache, the recovery time can be shortened significantly.
