Linux: finding System Hardware Information – Manufacturer, Model/Product Name, Serial Number and Physical Sockets, Processors/CPUs, Cores

Finding Hardware Manufacturer, Model/Product Name, Serial Number:

 

[root@ProdDB01 ~]# dmidecode -t system
# dmidecode 2.7
SMBIOS 2.3 present.

Handle 0x0100, DMI type 1, 25 bytes.
System Information

        Product Name: ProLiant DL385 G1
        Version: Not Specified
        Serial Number: UXXXXXXXXXX
        UUID: 3xxxx1x1-3xx8-3xx3-4xx5-3xxxxxxxxx48
        Wake-up Type: Power Switch

Handle 0x2000, DMI type 32, 11 bytes.
System Boot Information
        Status: Firmware-detected hardware failure

[root@ProdDB01 ~]#

Finding Physical Sockets, Processors, Model, Cores:

You can find all of the details about system processor from below file location: Use grep to find the specific details

less /proc/cpuinfo

 

Physical Sockets (Processor Slots on the Mother board of a Computer):

[root@ProdDB01 ~]# dmidecode -t processor | grep -i "Socket Designation"
        Socket Designation: Node 1
        Socket Designation: Node 2
[root@ProdDB01 ~]#

[root@ProdDB01 ~]# grep "physical id" /proc/cpuinfo | sort -u | uniq | wc -l

2

[root@ProdDB01 ~]#

 

The number of “Physical Cores per Socket”:

[root@ProdDB01 ~]# grep "cpu cores" /proc/cpuinfo |sort -u |cut -d":" -f2

2

[root@ProdDB01 ~]#

 

The number of overall Cores (that appear logically to the OS):

[root@ProdDB01 ~]#  cat /proc/cpuinfo | egrep "core id|physical id" | tr -d "n" | sed s/physical/\nphysical/g | grep -v ^$ | sort | uniq | wc -l
4
[root@ProdDB01 ~]#

Or

[root@ProdDB01 ~]# grep -c "processor" /proc/cpuinfo

4

[root@ProdDB01 ~]#

FYI.
