To address this, the logs are placed on fast write cached disks, reducing the disk write time. 为了解决这个问题,把系统放在快速写入(FW)高速缓存磁盘上,以减少磁盘写入时间。
Utilize disk storage with fast write cache for the logs. 为日志分配一个具有快速写入(FW)缓存的磁盘存储器。
Database update operations ( such as update, insert, and delete ) all benefit when the database log is located on a fast device, such as a disk with a fast write nonvolatile cache. 当数据库日志位于高速设备(例如带有高速写非易失高速缓存的磁盘)时,数据库更新操作(例如更新、插入和删除)都将受益。
On Windows and AIX, write cache is available through the use of SSA disks with a fast write nonvolatile cache. 在Windows和AIX中,可通过使用带有高速写非易失的高速缓存的SSA磁盘来获得写高速缓存。
In R = 1 and N = W we optimize for the read case and in the W = 1 and R = N we would optimize for a very fast write. 当R=1且N=W,对读操作是最优的。当W=1且R=N,这样的优化可以得到非常快速的写操作。
