A few years ago, we purchased 8 "identical" Dell Poweredge 2950 servers.
Service tags were all very close together.  They were all built and
deployed to 4 different locations.  (in pairs)

After running in production for a while we encountered an intermittent hang
on a couple of them which was potentially addressed by a DRAC firmware
update that had been released since they were deployed.  We tested the
update on a test system and nothing broke so we deployed it to the
production systems.  Out of 8 systems, we got about 6 different results.  2
of them bricked the DRAC requiring physical replacement of the board.  4 of
them failed in different places but a subsequent attempt to flash the
firmware was successful. 2 of them updated with no problem.

These were ostensibly identical systems being flashed from one identical
version to another identical firmware version.
