体现在读与写两个不同的方面,如果作为写,一般存储阵列只要求写到cache就算完成了写操作,所以,阵列的写是非常快速的,在写cache的数据积累到一定程度,阵列才把数据刷到磁盘,可以实现批量的写入,至于cache数据的保护,一般都依赖于镜像与电池(或者是UPS)。 cache的读一样不可忽视,因为如果读能在cache中命中的话,将减...

This is very comforting when you have a drive failure and have to replace and rebuild a drive – with only single parity, if another drive fails during the rebuild process, you will lose data. Dual-parity keeps you protected while replacing a failed drive. Again, if MORE than two drives ...
The parity is something rather interesting, each part of the parity drive holds the value of all other drives x-ored, so you can rebuild any one drive. Note that this only works, when you replace that drive on its own, not, when you replace 1 failed drive with 2. Adding a second p...
If you set up a cache drive in your Unraid server, you can save the transfer data to the cache drive first. Unraid would then transfer the data to the array at a later time. Because the cache drive is a solid-state drive, the data transfer would be faster than when saving directly ...

then expanding your array is quite simple. Just remove any drive from the array and replace it with a larger one. From there, you just tell the software what you did and it begins expanding to have a new capacity that includes the increased size of the drive you just inserted. This oper...
