If you're putting together a compute farm or web cluster, RAID-0 is an excellent way to increase disk IO performance.
如果您正在设置computefarm或web集群，RAID - 0是一种提高磁盘io性能的极佳方法。
On Windows NT, the disk queue length is the best indicator of I/O saturation, and it should be less than the number of disks in the data RAID set minus one.
在WindowsNT 上，磁盘队列长度是I/O饱和程度的最好指示器，并且它应该小于数据RAID集中的磁盘数减去 1。
Because the Domino server can be very disk intensive, configuration of disk drives, and arrays of hard drives called RAID drives, can greatly enhance server performance.
由于Domino服务器有时需要占用大量磁盘，因此磁盘驱动器和RAID设备的配置可以极大地增强服务器性能。
