Looking to build a couple of production servers, so I was thinking about 
heading to the local 'recycled' store for off-lease systems.

Only problem is, it's really hard to figure out if the RAID controllers are 
compatible (e.g. Perc 3 vs. OpenBSD Perc 5); can anyone share any 
recommendations? For example:

Dell 16005C (Perc 3 SC),  4600 (Perc 3 DC-128), 600SC (Perc DAT8)
Compaq ML350GB (Smart 532), ML370 G4 (Smart 642)

	TIA,

	Lee

Avoid the Adaptec ones which are conveniently also marketed as PERC.
Anything >= PERC4 should be AMI/LSI based and works.

The PERC3 DC/DCL/SC should work too.  Again make sure you don't end up
with something adaptec (they do have different designations but my
memory fails me).

Can't comment on the HP stuff since I don't use it.

Actually the ami list in the man page is pretty exhaustive.

The Compaq/HP Smart 5 and above controllers (ciss) should work well. 
Note the caveat at the bottom of the man page.

"ciss" and "work well" in one sentence without a negation involved?

I have several, and haven't experienced any problems.  To which PR are 
you referring?  I have a bunch of HP hardware here, perhaps I can 
duplicate the problem and at least see if I can find a workaround.
