IBM-AIX:
CPU、内存、磁盘，只需运行nmon命令即可。
查看OS版本号:oslevel -r

linux 
cat /proc/cpuinfo/grep processor

AIX
lsdev -C | grep -i rocessor| wc -l
或直接运行nmon命令

Solais
psrinfo -v | grep "Status of processor" | wc -l

hp-unix
ioscan -C processor | grep processor | wc -l

// 显示内存数量
Linux:
free

AIX:
lsdev -C | grep mem

Solaris:
prtconf | grep -i mem

memo     Available   00-00 Memory

可见mem0是该aix设备上的内存设备名称，现在使用lsattr -EI 来查看该服务器上的内存数量

root>lsattr -EI memo
