The best and most reliable way of doing that is probably to open the server
and look inside to see what is installed (or look at the paperwork from when
you originally bought the servers.) 

When you boot the BIOS will often display this information as well.

You could also try the sysutils/dmidecode port which will try to retrieve
various information from the BIOS.  Beware though that due to buggy BIOSes
you cannot always trust this information.

If none of the above works, I am afraid you are out of luck,

A note for future consideration:  When you have remote servers, or servers
which must not be shutdown if it can be avoided, then it is a very good
idea to write down on a paper exactly what is installed in each of them, at
the time they are first installed.  This can simplify things quite a bit
a couple of years down the line.
