m4000的内存条能混插么？

milujite

咨询下各位，M4000的内存能否混插，如1G和2G的内存一起使用。

不同的板上应该可以，同一个板貌似不行

不同板子也不行，所有板子必须A组相同，B组相同。

这个A组和B组是怎么划分的呢？这个是从文档里翻的M4000的拆机图

Memory Installation Configuration Rules
You can mount up to 4 memory boards on the SPARC Enterprise M4000 server and
up to 8 memory boards on the SPARC Enterprise M5000 server. The DIMMs on the
memory board are grouped into group A and group B. (See FIGURE 11-4).
Here are the DIMM mount conditions:
■ In each group, 4 DIMMs are mounted in a unit.
■ The size of the DIMMs in group A must be equal to or larger than the size of the
DIMMs in group B. You need not necessarily mount DIMMs in group B.
■ In each of the groups, mount the DIMM of same size and of same rank. The
DIMMs of different size cannot be mixed in a group.
■ To replace with the DIMMs of different size or different rank, you need to follow
the above conditions on every memory board in the same CMU.
Note – When you upgrade using larger size memory than the size of Group A, move
the memory mounted in Group A to Group B, and then mount the upgrade memory
to Group A.

M4000只有4个内存板，每个内存板8个DIMM，并且分为AB组。每个组里，4个DIMM为一单元。A组的内存容量必须大于或等于B组，B组DIMM不是必须插的。在每个组里，内存容量需要一致。是这样解释么？最后那句没明白~

不容，请蜘蛛姐湿一下吧。

M5000内存是最搞的，要想麻烦少，就选PN号且厂家一样的

我一般都告诉客户，机器上所有的内存都必须一摸一样，连A-B组都懒得解释。
