Ode to the Dell C2100/FS12-TY

Now hopefully the RAM issue that I had initially doesn't come up at some point too :p
My MB/CPU combo didn't like DDR3L for some reason; I could run with a different CPU with my RAM no problem; I could run with my CPU and DDR3 non-low voltage. I ended up mixing the DDR3 (I had 2x8GB, not enough to run on) and DDR3L (8x8GB, what I bought) which forced the DDR3L to run at standard voltage and works without issue besides a message complaining about it.

UPDATE: I swear to god this thing is gonna give me a heart condition. I've started the burn-in testing using the SAS->SATA ports since the drives autonegotiate to SATA2 and they've hit 46C compared to the other drives at 40C. I guess I'm going to have to unquiet my BMC to get some higher fan speeds, good thing this thing is in an unused room.
As far as RAM goes, I personally exclusively use Samsung M393B2K70CM0-YF8 (Example: https://www.ebay.com/itm/Samsung-M3...398569?hash=item2ad16fe869:g:rLgAAOSwxm5dPigB). I tried best never to mix RAM to avoid any issues.

What drives are you using again? If they are SAS, expect them to run hotter. Especially if you are burning them in anyways.

In all honesty, I have always had my Critical Temp Warning set at "48" and really never had issues (for both SAS and SATA drives). Most people would say I was running too hot, but if you check the actual Vendor specs of your drives, you may be surprised at what temps they can really handle. Example: I have a server filled with 12xHGST 4TB SAS (HUS724040ALS640). Per the Specs, Ambient Operating Temps are 5 to 60 C; so personally I feel my setting of 12C below max is safe.

My Servers run 24/7 in my "basement office" not more than 6 feet from me (in a Dell Full Server Rack). However, when I first moved everything there a few years ago I did stick a standing fan in front of the rack running on low just because I had moved everything from my hot garage (concrete floors hold crap tons of heat during summer). This is not due to me worrying about any particular Server, it was because I have 4 of them running along with a Raritan KVMoIP, 1GB Switch, 10 GB Switch, UPS, Raritan PDU, 17" Dell Slide Out Monitor/KB/Mouse, etc..

I have considered exploring the Dell R730xd, since the C2100/FS12-TY are super antiquated; but just can't bring myself to it. Heck I still have 2 Servers with 24x2.5" bays I have been waiting to fill when SSDs get really cheap. :)

Last note, I still run FreeNAS-9.10-STABLE-201605240427... ;)

Yeah, I wouldn't have mixed the RAM if I could've avoided it at the time (had less money/didn't want to invest too heavily in my first project).

They are SATA drives, WD140EMFZ. I just shucked them the other day, they are 14TB and should also be Helium. They might be running hotter because I think they are a bit larger physically and may not be letting as much air pass, and combine that with them being on the right side, connected to the SATA breakouts, where they are further from the fans. I'll keep an eye on their temps but I did raise critical to 50C last night after some reading about it.

I couldn't even consider the R730xd, I think that's still over $1k on ebay. I have been looking at the R720xd a little bit because I saw a listing for ~$400 and I could consider not needing a new backplane ~$100 discount. I kinda have been thinking about if it could lower my power usage a bit (newer CPUs being more efficient). I could reuse my RAM since it's still DDR3, and it has more fans so if it lets me tweak the curves to be less aggressive I'd bet it could be pretty quiet.

I've also thought a little bit about rolling my own since I could then upgrade pieces as I go instead of the entire thing but I don't know enough about the market to be able to find good-quality cheap parts. An fully assembled unit (even if it's missing RAM or CPU) is a bit easier to deal with.

However, I'm not sure how much of a power savings I'd get if at all with an upgrade to an R720xd or even a DIY; so I don't know if I could consider it really worth it. But damn does looking at the newer design of the R720xd get me drooling a bit.
