    Abstract: Provided are a device and method of controlling a dish cache, wherein a time of seeking a disk cache may be shortened and a hit rate of a disk cache may be increased. The device includes a main memory including a buffer cache, a flash memory including a flash cache, and a controller controlling the buffer cache and the flash cache, wherein the buffer cache and the flash cache are enabled to cache a data block stored in a disk, and the controller identifies a position where the data block is cached using metadata.

    Abstract translation: 提供了一种控制盘缓存的设备和方法,其中可以缩短寻找磁盘高速缓存的时间并且可以增加磁盘高速缓存的命中率。 该设备包括主存储器,其包括缓冲器高速缓存,包括闪存缓存的闪速存储器以及控制缓冲器高速缓存和闪存高速缓存的控制器,其中缓存高速缓存和闪存高速缓存被使能以缓存存储在盘中的数据块 ,并且控制器识别使用元数据来缓存数据块的位置。
