官方说明下,就这个区别
PERC 6 and CERC 6/i Controller DescriptionsThe following list describes each type of controller:
- The PERC 6/E adapter with two external x4 SAS ports and a transportable battery backup unit (TBBU)
- The PERC 6/i adapter with two internal x4 SAS ports with or without a battery backup unit, depending on the system
- The PERC 6/i Integrated controller with two internal x4 SAS ports and a battery backup unit
- The CERC 6/i modular storage controller with one internal x4 SAS port and no battery backup unit
然后在使用手册上“表 2-1. PERC 6 和 CERC 6/i 控制器比较”里,唯一区别就是adapter的bbu "PERC 6/i 适配器仅支持选定系统上的电池备份单元 (BBU)。"( http://supportapj.dell.com/suppo ... C6/cs/PDF/cs_ug.pdf )
这两个说明的地方都相互证明了 |
