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。
