I have attempted to put an SSD as a boot drive into a G5 XServe (10.4.11) and a Xeon XServe (10.6.7).
The drive was a OWC 60GB Mercury Extreme Pro 6G.
I cloned the original boot drive with Carbon Copy Cloner in both cases. In the G5, I got a kernel panic on boot. In the Xeon, I had the same experience as you; the drive would not be recognized.
OWC sent me a replacement drive to try. The results were identical with the Xeon XServe.
Interestingly, both XServers would work fine if I used the SSD in a Voyager dock and the FireWire 800 port.
I asked tech support at OWC to kick this up to their development team, today.

The issue is that apple really tried to corner the drive market with the xserve. The only drives that will reliably work every time is an apple branded server class drive. All external drives will work just fine its just the internal ADM drives that will cause issues. Others have found that certain model hard drives will work. Some found that using a jumper to swich from 3gb to 1.5gb made the drive work.
Anyway good luck it would be great to find an ssd drive that would work as a boot drive.

The only one aftermarket SSD I found to WORK in the 2006 Xserve Xeon is the OCZ Vertex 2 3,5". Other drives I tried and found NOT to be recognized (to spare you the pain): Crucial M4, Samsung 840 Pro Series, SuperTalent SuperNova SSD.

just to follow up, this drive (vertex 4) actually did mount on my system (!!), finally after trying crucial m4 and owc and some kingston thing, this one works. so far. am cloning to it now, but it formatted and passed fsck several times. so fingers crossed.
wanted to post in case anyone else is trying to keep the venerable old xserve alive. i like the thing. will miss it when it's finally gone. fortunately for me the computing power in it is all i need to run the operation here, so as long as it kicks, it'll have a job.

i take it back. it mounted. it formatted. it took a clone. it passed utility tests. it repaired perms. it passed util again. restart. didn't see it. restart. didn't see it. new bay. didn't see it. amber light. red light. new bay. red light. restart. no joy.
well. it mounted for a while. but this is in no way useable as a server drive.
this. really. *****.
i was getting very excited to finally migrate some volumes to ssd.
APPLE! what are you doing to me here???? this is bs. could you kindly allow us to use ssd's on the xserve for f----s sake!
anyway. f. y. i......

thx semmel. i did pay attention to your post, that's why i asked about the 4, which, yes, is overkill for the xserve in terms of speed.
so, i tracked down a vertex 2 and will try.
but can you tell me, have you successfully used a 2 as a boot drive on xserve, and what is your failure rate with it, uptime?
thx for replying!

I had been using a 3.5" model (Vertex 2) as boot drive in my late 2006 Xserve since July 2011 and recently replaced it with a 2.5" Vertex 2 with bigger capacity. As I said, it runs as a boot drive and also runs a database on it. Works like a charm!
The Vertex 4 obviously will not work as boot drive though.
