In this work, we propose a cache design method over flash memory without any additional hardware support for storage servers. In particular, a scalable set-associative flash-cache management design is proposed to significantly improve the flash endurance with excellent caching response time and hit rates. The capability of the proposed scheme was evaluated by extensive experiments over Microsoft's server traces, in which significant improvement on endurance was achieved, compared to existing work. © 2013 IEEE.Endurance aware design; Flash cache management; Set-associative; Storage servers[SDGs]SDG7Associative storage; Cache memory; Digital storage; Energy efficiency; Monolithic microwave integrated circuits; Storage management; Virtual storage; Windows operating system; Cache design; Cache management; Data centers; Disk based storage; Energy efficient; Hardware supports; Set-associative; Storage servers; Flash memoryjournal article10.1109/TC.2013.119
