Everyone has been so helpful on this list and I have pretty much decided to get the SB 100 based on its size and it looks like it will hold 3 hard
drives without a problem. Also, I can get a rack mount kit for it.

I would still like to get some more advice.

I have been using a Mac G3 running NetBSD (of course). I added an ethernet card and a scsi controller. They configured and work fine in the Mac. Just
so there is no confusion, I copied part of my dmesg from the Mac:

So, I have 2 - 250 gb ide drives on the scsi chain with scsi-to-ide
bridges. The scsi controller and the network card seem to work flawlessly
on the mac. I have a private network for my servers, so I will need a
second network port (the SB 100 only has 1). My question is this, will
these 2 cards work as well in the SB 100 as they do in the Mac, or would a different hard drive controller and eliminating the 3 scsi-to-ide bridges work better? It would be great if someone could tell me what has worked for them with large drives. I could use a different ethernet card if need be, but this is what the colo has so if it ever failed, they could just
put one in.

Mose Suns have firmware support for SymBIOS 53C8xx SCSI controllers so you can probably even boot from your esiop. About the fxp - I've never used one in a Sun but if it works in a Mac there's a pretty good chance it will work well in a Sun as well, most alignment bugs would have bitten on the Mac already.

have fun
