* https://wiki.debian.org/HowToIdentifyADevice/PCI

Savoir si il y a du SAN :

<code bash>
lspci |egrep -i -e "emu|qlo"
</code>


Avoir plein d'infos avec dmidecode

<code bash>
#dmidecode  |grep -e "Product" |head -1
dmidecode -s system-product-name
</code>
<code ->
Product Name: PowerEdge R710
</code>

<code bash>
dmidecode -t1
</code>

Firmware version check for Dell server

<code bash>
dmidecode | grep -i serial
dmidecode -t 1
dmidecode -s system-serial-number
</code>

<code ->
# dmidecode -s baseboard-manufacturer

<code bash>
cat /proc/bus/input/devices
</code>

Quelques commandes utiles :
* dmesg
* ''lsusb -t'', ''lsusb -v -d 1050:0120''
* lspci
* ''lsscsi -H'', ''lsscsi -g''
* lshw
* inxi
* lscpu
* lsblk
* dmseg
* ''hwinfo --short''
* /sbin/discover
* lsdev procinfo (paquet procinfo)
* lsmod
* ''numactl --hardware''

Un lsmod peut également révéler beaucoup d'information sur le matériel



== CPU

<code bash>
nproc
lscpu
lshw -c cpu
dmidecode -t processor
cpupower monitor
</code>

<code ->
iucode_tool --scan-system
iucode_tool: system has processor(s) with signature 0x000406f1
</code>

== Disques

<code bash>
lsblk
lsblk /dev/sda --bytes --nodeps --pairs --paths --output SIZE,ROTA,RO,TYPE,PKNAME,NAME

fdisk -l
parted -l
hdparm -i /dev/sda

systemctl list-units --type=device
</code>

== Réseau

<code bash>
lshw -c network
</code>

Si ''UNCLAIM'' apparaît : probablement un problème de driver

<code bash>
lspci |grep -i net
</code>

=== Nombre de cores nombre de processeur physiques

<code bash>
cat /proc/cpuinfo
</code>

Nombre de core
<code bash>
nproc
getconf _NPROCESSORS_CONF
</code>

== GPU

<code ->
# inxi -G
Graphics:  Device-1: Intel driver: i915 v: kernel
           Device-2: NVIDIA driver: nvidia v: 430.50
           Device-3: NVIDIA driver: nvidia v: 430.50
           Display: tty server: X.org 1.20.4 driver: none tty: 237x35
           Message: Advanced graphics data unavailable in console for root.
</code>

=== Exemple

<code ->
LANG=C lscpu | grep -i socket
Core(s) per socket:    10
Socket(s):             2

grep -i "physical id" /proc/cpuinfo | sort -u | wc -l
2

nproc
40

Hyper-Threading ?
grep -o -w -e '^flags.* ht' /proc/cpuinfo

Si non :
NBSockets * CoresPerSocket

Si oui :
NBSockets * CoresPerSocket * 2
</code>

== Carte graphique

Identifier sa carte graphique
<code bash>
lspci -vnn | grep -A 12 '\''[030[02]\]' | grep -Ei "vga|3d|display|kernel"
sudo lshw -enable pci -class display
xrandr
</code>
