可见已有3块CPU BOARD 4块MEM BOARD

新加一块CPU BOARD 再加一块 2GB X 8的MEME BOARD

官方文档上关于内存的插法，参考下：
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.

Only half or fully populated memory boards may be installed
In Uni-XSB mode, 1, 2 or 4 memory boards can be installed per PSB, all must have
the same capacity. (3 memory boards is not allowed).
■ In Quad-XSB mode, each CPU module must have 1 half populated memory board
or 1 fully populated memory board; capacity can be different.

我感觉新加内存会有问题

Answer 1

yep, 我是在说CPU BOARD 和MEN BOARD 的数量...

Answer 2

回复 4# watchsat

    我感觉你是在说MEM BOARD内部的DIMM

我说是CPU BOARD 和MEN BOARD 的数量 ：）

Answer 3

CPU board 可以是奇數, RAM module 一定是偶數, whatever the configuration is 2-ways or 8-ways.

Answer 5

现在已经有4块内存板 再加一块 一共5块 单数不行啊
