申威服务器配置信息查看演示

第一章：常用命令

① 显示服务器信息

通过 dmidecode|grep "System Information" -A9|egrep "Manufacturer|Product" 命令可以显示服务器信息。

申威服务器没查出来，其它服务器可用，下面这个是飞腾服务器的。

root@compute9:/opt/dmdbms/tool# dmidecode|grep "System Information" -A9|egrep "Manufacturer|Product"
        Manufacturer: GreatWall
        Product Name: 擎天DF720

下面这个是泰山服务器的

[root@taishan-kylinosv10-18 yonyou_nc]# dmidecode|grep "System Information" -A9|egrep "Manufacturer|Product"
        Manufacturer: Huawei
        Product Name: TaiShan 2280 V2
