A couple things, a server is pretty much meant not to
sleep. Do or did you have all server functions turned off?
Any of them may have some ability of setting a flag
somewhere to prevent sleep.
I have a new Mini Server that I use for a workstation
(turned off server function). I never sleep the Mini
as I always shut down. Only sleep my display if
I'm only going to be gone for a short time. However,
on one of those occasions, I accidentally hit the key
combo to put the computer to sleep instaed of display
sleep and the Mini Server did in fact go into sleep.
When I returned later, I saw the little LED pulsing
indicating sleep. It was a bummer since I wanted the
thing to clone while I was gone. But the point is it
did sleep.
I don't recall doing anything special when setting up
but it did sleep, much to my dismay (kicked myself
for the screwup).

BTW, just tried the Sleep from the Apple menu and it
went right to sleep. I looked through all the Preferences
and didn't see anything different than on my other Macs.
So the new Mini Server can sleep. Perhaps it may have
been the fact that when I started up the very first time
I did not enable any of the server services. Other than
that I know I didn't do anything special.
