(Speaking of RAID (redundantarrayofindependentdisks), now it has almost become one of the technologies that network administrators must master, especially in small and medium-sized enterprises. Because disk array is widely used, it is one of the main schemes for data backup at present. However, many network managers only saw the introduction of relevant theoretical knowledge on various media, but did not see some actual disk array configuration methods, so they still only knew a little, but had no way to start when they really configured. This article will take a specific disk array configuration method as an example to introduce some basic configuration methods of disk array, and give some key interfaces, so that you can have a rational understanding of the configuration of disk array. Of course, in order to give you a more comprehensive introduction to disk arrays, let's first briefly review the theoretical knowledge about disk arrays, so as to find a theoretical basis for the actual configuration.)
