Modern file systems assume the use of disk, a system-wide performance bottleneck for over decade. Current disk caching and RAM either impose high overhead to access memory content or fail provide mechanisms achieve data persistence across reboots.The Conquest system is based on observation that becoming inexpensive, which enables all services be delivered from memory, except providing large storage capacity. Unlike caching, uses with battery backup as persistent storage, provides specialized separate paths disk. Therefore, path contains no disk-related complexity. The consists optimizations only usage pattern.Compared memory-based system, incurs little overhead. Compared several disk-based systems, achieves 1.3x 19x faster performance, 1.4x 2.0x when exercising both realizes most benefits at fraction cost RAM-only solution. It also demonstrates overheads accessing in memory-rich environment.
