Exadata存储节点的CPU限制成功了没?

[root@dbm08celadm03 ~]# mpstat
Linux 4.14.35-1902.306.2.1.el7uek.x86_64 (dbm08celadm03.oscbj.com) 2021年06月07日 _x86_64_ (64 CPU)
10时50分22秒 CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle
10时50分22秒 all 3.39 0.01 2.21 0.00 0.00 0.00 0.00 0.00 0.00 94.39
别急,我们实际去查询/proc/cpuinfo信息,发现已经是32个processor:
[root@dbm08celadm03 ~]# grep processor /proc/cpuinfo
processor : 0
processor : 1
processor : 2
processor : 3

processor : 55
[root@dbm08celadm03 ~]#
[root@dbm08celadm03 ~]# grep processor /proc/cpuinfo |wc -l
32
进一步使用cellcli查询存储节点的详情:
[root@dbm08celadm03 ~]# cellcli

也可以看到“cpuCount:”显示为“32/64”,说明存储节点的CPU是限制成功的。
