Is this just a file server or is it going to be supporting a web page or something of the nature as well?
if it is a file server i wouldn't suggest RAID 1 for a file server, get a third drive and do raid 5, which uses parity (basically the computer uses 1+0=1, if it loses one part of the equation/one drive, it can figure out what it was supposed to be. Think algebra.)
Since it uses one drive to calculate the parity, you will lose the size equal to 1/3 of the array, and all drives must be the same. You will have 2Tb if you get another Tb drive or you could get 3 500's and have the size you have now. It would be good for a price comparison.
Might bump that up to 8Gb too depending on how heavy your use is.
not really sure why you only have a 500gb for your external backup, however. I'd either go with a 1tb or just do cloud-based.
other than that it looks okay to me.
thanks for the quick responses.. I forgot to mention, it will be mainly used as a file and print server.
"We use a dental practice management software package called Dentrix that is basically a database that the workstations get info from and display it, all our records are electronic, all the x-rays are digital, paperless charting. So reliability is important,
So is dual CPU overkill, vs using something like a single quad core sufficient since the server isn't running any applications beyond the Dentrix database and a SQL database for the digital images? I don't want to have to upgrade again for at least a couple of years (probably 5 or so). Is a faster single processor better for database access vs multiple processors at a slower speed? Or should I even care?"
dont worry about it. The rig you listed is perfectly ok for your needs. and like you said you dont want to have to upgrade for a few years so overkill in this instance is a good thing. but dont forget your UPS!
yeah the single processor you have listed will be fine for a 10 PC setup, A file server will mostly be about the speed of the drives, which is why a RAID 5 would be better as well (2 drives writing data instead of one) and it would seem to be fully capable.
As finn said, grab a UPS and I'd reccomend Raid 5 and see what the price would be on 8 gigs of ram (i'm not sure if they're using 2 sticks of 4 or 4 of 2 or what but i know that ECC ram is fairly expensive)
