    Single server colocation for high-power GPU compute application

    I've got a single 3U server with 3 GTX 590s. These 590s are going to be loaded at 100% basically 24/7, and I've calculated the power requirements and it seems like I'll need something around 10A (120V) to do this.

    The thing is, most providers only seem to offer 1A, and some offer 2A for single-server colo. Most even offer half racks with only 20A.

    I don't need much bandwidth and so the transit providers are not a very important issue. Also, I am located in the US but I have no location requirements. Europe would also be acceptable. All I need is a fairly reliable place to put the box.

    TIA!

    Most likely you'll end up needing a half rack with a 20amp power feed, 16amp usable. What is your budget? Measure the amp usage, rather than guesstimate it. 10amps sounds high, but you didn't specify processor, fans, disks, etc.

    20amp (without rack space or bandwidth) typically costs $200-$400/month at colo providers.

    Going to email a couple providers now and see what they can do.

    The processor will be an i7 930 and I'll most likely underclock it, as it won't be used much. (The only reason I went X58 is because of the PCIe lanes.) Only one 7200 RPM HD.

    Budget for a single server is going to be a few hundred a month at most - let's say $400-$500. I'm not sure if this is realistic or not, so this isn't quite set yet.

    Thanks all!

    Someone else a few months ago was doing the same thing and had the same questions.
    The biggest factor in colocation will normally be power usage, so you will end up paying the typical price you see quoted for half racks, etc even though you aren't using much bandwidth.

    See thread here: http://www.webhostingtalk.com/showth...=graphics+card

    Yep, I saw that thread but he was only looking at LA DCs. I'm actually going to look into Phoenix, since I'm in AZ, and there's apparently low power costs there.

    Check with GoRACK in Jacksonville, FL. I use these guys and I love how they offer custom colo packages where you pay for the exact amount of everything you plan to use. I found their last offer in the Colo section and figured your monthly rate would be $185.39 for a 3U server needing 10A of power with only 1Megabit BGP bandwidth and 3 IPs.

    Put it in your house with a static IP if you don't need a lot of bandwidth.

    That's true about the basic packages offered by most colocation providers, but there are plenty of companies out there who will happily come up with a quote for what you need. Colocation is all about supporting the needs of the customer's equipment, so providers are almost always willing to modify a package (along with the price). As mentioned up-thread, send out some requests for quotes. Since you already have a good idea about what you need it should be easy for any provider to send you a quote.

    Id start with undervolting it rather than underlocking it

    You might check out PhoenixNAP. Their 1/4 cabinets come with a 20A circuit. ($299/m) Site doesn't list bandwidth being included, but they will probably throw you a couple Mbps in with the price.

    Just my two cents

    You need to take full circuit 20A (16A usable) if you use more than 10+A or find out provider who give 220V.

    check with PhoenixNAP or colounlimited
