on my Dell Poweredge R710 server with vmware esxi 6.5 os, I installed perccli.

when 'perccli /c0 show' to get the RAID controller serial number I see a serial number as 1122334455667788

Is this an actual manufacturer given serial number or a tool generated serial number because I saw the same serial number for a RAID controller on a different Dell Poweredge R710 server with vmware esxi 6.5 os, as well, when  running 'perccli /c0 show'
The serial number should be unique right?

How can I get an actual serial number for the RAID controller using perccli command
