Linux system View motherboard model, CPU, memory, memory number, network card information

Description

Because of all the original, we may need to look at the Linux Server board model, CPU model, memory size, the number of memory lines. Because the server uses a RAID card, the usual view of the hard drive information can not be used, to be added back later!

View Motherboard model

The code is as follows	Copy Code
# 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 is filled by O.E.M. Family:server Online check Dell Cs24-ty to find that the motherboard model is the Dell PowerEdge C1100

View Memory

code is as follows	copy code
# free-m Total used free shared buffers Cached mem:32103 31803 300 0 217 953 -/+ buffers/cache:30632 1471 swap:16383 476 15907
