磁盘高速缓存路径 diskCachePath
集成高速缓存磁盘阵列 Integrated Cached Disk Array
另外，通常需要高速磁盘或数据库(或二者)，以增加缓存大小，或获取高可用性。
Additionally, high-speed disks or databases (or both) are typically required to increase the size of the cache, or for high availability.
通过将暂挂的写操作放到高速缓存中，硬盘固件就可以重新为它们排序，并为它们分组，以便用尽可能最快的方式将它们写到磁盘中。
By putting pending writes into a cache, the hard drive firmware can then reorder and group them so that they're written to disk in the fastest possible way.
为了解决这个问题，把系统放在快速写入高速缓存磁盘上，以减少磁盘写入时间。
To address this, the logs are placed on fast write cached disks, reducing the disk write time.
