LSI 阵列卡的工作模式
MR - MegaRAID 模式
使用 RoC 芯片硬件实现 RAID 功能，常见的带缓存的阵列卡工作在此模式，如 ServeRAID M5210、RAID720ix、9260-8i等
iMR - Integrated MegaRAID 模式
通过软件（驱动）实现高级 RAID 功能（如 RAID5 ），常见的不带缓存的阵列卡工作在此模式，如 ServeRAID M1215 及移除缓存模块的 ServeRAID M5210、9240-8i等
IR - Integrated RAID 模式
提供最简单 RAID 功能（RAID0/1/1E）的 SAS 卡工作在此模式，如 ServeRAID H1110 等
IT - Initiator and Target模式
即直通模式，无任何 RAID 功能，SAS HBA 卡工作在此模式，如N2215、N2225等

JBOD 配置
JBOD 原理
JBOD （ Just a Bunch Of Disks ）不是标准的 RAID 等级，它通常用来表示一个没有控制软件提供协调控制的磁盘集合。 JBOD 将多个物理磁盘串联起来，提供一个巨大的逻辑磁盘。 JBOD 的数据存放机制是由第一块磁盘开始按顺序往后存储，当前磁盘存储空间用完后，再依次往后面的磁盘存储数据。 JBOD 存储性能完全等同于单块磁盘，而且也不提供数据安全保护。它只是简单提供一种扩展存储空间的机制， JBOD 可用存储容量等于所有成员磁盘的存储空间之和。目前 JBOD 常指磁盘柜，而不论其是否提供 RAID 功能。
