linux查看主板型号,cpu,内存,内存条数量,网卡等

说明：
因为种种原来，我们可能需要查看linux服务器主板型号，cpu型号，内存大小，内存条数量等。因为服务器使用raid卡，平常查看硬盘信息的命令还不能用，待后面补充！

实现：
查看主板型号

# dmidecode |grep -A 8 "System Information"
System Information
        Manufacturer: Dell
        Product Name: CS24-TY
        Version: A00
        Serial Number: 24Z1NL1
        UUID: 2656CFCF-887A-0010-BBD8-00269E9C46DC
        Wake-up Type: Power Switch
        SKU Number: To Be Filled By O.E.M.
        Family: Server

上网查DELL CS24-TY，找到说主板型号是DELL PowerEdge C1100
查看cpu型号，主频

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
      8  Intel(R) Xeon(R) CPU           L5520  @ 2.27GHz

 
查看内存

# free -m
             total       used       free     shared    buffers     cached
Mem:         32103      31803        300          0        217        953
-/+ buffers/cache:      30632       1471
Swap:        16383        476      15907

 
查看内存条数

[root@localhost ~]# dmidecode -t memory|grep Size
        Size: 8192 MB	Type: Other	Speed: 1333 MHz
        Size: No Module Installed
        Size: No Module Installed
        Size: 8192 MB

查看硬盘大小，分区

[root@localhost ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             119G   17G   96G  15% /
tmpfs                  16G     0   16G   0% /dev/shm
/dev/sda1              97M   32M   61M  35% /boot

 
查看raid卡，raid卡为DELL PERC 6/i

[root@localhost ~]# dmesg |grep -i raid
dracut: rd_NO_DM: removing DM RAID activation
dracut: rd_NO_MD: removing MD RAID activation
ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 6 ports 3 Gbps 0x3f impl RAID mode

scsi6 : LSI SAS based MegaRAID driver
[root@localhost ~]# cat /proc/scsi/scsi

查看网卡

[root@localhost ~]# lspci | grep -i 'eth'
05:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
05:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

 
查看21号网络流量

# sar -n DEV  -f /var/log/sa/sa21 |grep eth|less

 
查看板载显示信息

[root@localhost ~]# dmidecode |grep -A 5 "On Board Device Information"
