隨著RAID技術的不斷推廣,用戶有時很難全面了解不同RAID級別具體表示什么意思。大多數(shù)人都知道RAID0和RAID5的含義,但了解諸如RAID60和RAID5EE等其他RAID級別工作原理的人卻寥寥無幾。
不同的RAID級別對應于不同的性能、容量和可靠性,代表了這三種關鍵參數(shù)的不同平衡組合。
從最基本的角度來說,所有RAID級別均建立在RAID0、1、5和6這幾個基本RAID級別基礎之上。一些RAID級別衍生出某些少見的變種,比如RAID1E、5E和5EE,它們與RAID1、5的特性相似,不過更豐富一些。
下表歸納了四種基本RAID級別的工作原理,并根據(jù)性能參數(shù)、可靠性要求和用戶愿意提供的可用容量比較不同陣列方式的優(yōu)缺點。
