Dual Core Dual Opteron -- 1u or 2u?
Hey guys,
Just curious on what you guys think should be the recommended requirements for fitting a rackmount server with two dual core opteron 265 chips and two fast hard drives (10k rpm SATA or 15k rpm SCSI). What do you guys think... 1u or 2u, and what size power supply? Penguin computing offers a 1u unit with dual core opteron 265 chips with a 1u rackmount and a 450 watt power supply... however with the fast hard drives, the dual core dual chips... I'm worried about 1) heat issues and 2) power issues.
Also -- what's up with the Intel Woodcrest chips. Are they better than the dual core opteron's for game servers?

I recently got some quote from my hardware supplier for similar specked system and they are quite happy to qualify a 1U solution for those, those admitally I wasn't so sure. To be safe I might say 2U with plenty of ventilation, though if Penguin are supplying them I'm sure they have been fully tested for heat

Well -- even the best companies will supply you what you want -- not necessarily what you need.
Also -- do you know where to get just the 1u rackmount case -- or is it best just to get the barebones or a complete machine?

Had a bad run with 1U Dual XEONs, about 4 yrs back, so I will only buy 2U servers, even if you can't fit as many per cabinet. That's just my preference, and I love the extra ventilation in the 2U case.
Surely you can get the numbers to crunch with 18 x 2U servers per cab, over 1U servers. Leasing rackspace is not that pricey. I'll only buy servers with dual 550w power supplies.• WLVPN.com • NetProtect owned White Label VPN provider •

Assuming you're using a server-class motherboard (generally they're laid out in a way that makes passive cooling possible), and a good case, there should not be a problem. We use Supermicro cases for our high-end servers, which are designed with good cooling in mind, and they run very cool.

Same here. We use Supermicro cases and motherboards for the Opterons and haven't had any problems with heat in a 1U. In fact, the temperature coming out of an identical Dell is 15 degrees higher. I've seen that the IBM and Dell 1U servers generate a significantly more amount of heat than Supermicro does.

I have 2x 246 Opterons and 4x SATA drives in a 1U with a 400W power supply and it's running fine (Tyan barebones).

I'm running the exact same setup for Virtuozzo nodes (2x Oppy 265's and 4 hotswap 10k SCSI's), all in 1U cases without issues at all.
Granted these things throw out tons of heat in the office, but in a well ventilated DC they do just fine.

Supermicro makes some very nice cases which if you want to look at 1u are definatly worth taking a look at.
Another important thing is look at the DC you are going to be putting them in - can you get enough power per rack to fill it with 1us? If so they probably have adequate cooling for them if not you may want to look more at the 2u servers.John W, CISSP, C|EH

We were actually thinking of building them ourselves with Tyan barebones 1u. I.e., Dual Opteron 265 Dual Cores, 1 x 36GB 15k RPM HD, 1 x 73 GB 15k RPM HD, 4 GB of DDR ECC 3200 RAM (Kingston), etc. However, we'd need some sort of remote access capability, and Penguin Computing's systems come pre-built with the serial access card. Considering that's about $500 alone... it's actually around the same price to get it from Penguincomputing.
Servers are being placed in Equinix and Infomart.

Will they shutoff if the reach a certain temp? I know how bad it can be for an engine to overheat... can only imagine for CPU's.

Usually motherboards have a feature in the BIOS that will let you shut off the CPU at a certain temp.

Yep, Tyan refer to them as SMDC if you're looking for them, cheap as well - If you can get hold of them (Like most things Tyan, or anything decent, it's a pain to get them in here in the UK).
