CWC: Compressed Write Cache for Improving Storage System Performance


Fast non-volatile storage, such as non-volatile RAM and battery-backed volatile RAM, is widely deployed as the write cache in the storage controller to hide the latency of writes and prevent data loss. Due to the high cost of nonvolatile RAM and the short life of battery, the write cache is always much smaller than the read cache. To extend the size of… (More)
