ConnectX-3 serial number


I have a remote server with ConnectX-3 card installed, and need to get card serial number. Google shown there are two ways - one is using lspci -vvv in Linux, other is physically looking at the card. Well, but this SNs doesn’t look like eath other.

lspci -vvv gives something like this:

07:00.0 Network controller: Mellanox Technologies MT27500 Family [ConnectX-3]

Capabilities: [148] Device Serial Number 00-02-c9-03-00-23-90-30

Mellanox User Manual says SN should look like this one and could be seen on sticker on card itself: S/N:MT0744X00012.

What is the serial number provided by lspci? Is there any way to know SN from sticker remotely avoiding server shutdown and disassembling?



Hello Alexey,

We use this command to seek a HCA serial number which has already been installed on the host.


[root@R320-02 ~]# ibdev2netdev -v

mlx4_0 (MT4099 - MT1315X02691) CX353A - ConnectX-3 QSFP fw 2.11.500 port 1 (ACTIVE) ==> ib0 (Up)

I hope what I provided works for you.
