Colocation 1 AMP power for R610 with Intel 2X5650, 64 gig ram, 6X 5400 rpm disks?

yongsikleeyongsiklee Member, Patron Provider

Can a colocation 1 AMP power handle R610 with Intel 2X5650, 64 gig ram, 6X 2.5 inch 5400 rpm disks that are fully loaded with 10 VMs, and with 2x717 Watt PSUs?

Thank you.

    Those CPUs are 95w+ each alone.

    If calculate based on your PSU (Not based on max load), you will need about 13 Amp @ 110V

    You can use the Watts formula:
    Watt / Volt = Amp

    I am paying for $20 extra for having this server at home. I am thinking to colocate this.
    The replies above are helpful but do not reflect the real life power consumption.

    The CPU's are 95W each, so you have 200W+ in them even with a good efficient power supply. You then have the power of the drives (figure 5W each), and RAM is going to be around 5W/ea per stick too.

    You need 300W just to have some buffer in my opinion, since those CPU's will go over 95W if you're ramming them full blast.

    You will need 2 amps i have a similar server and pay for colo with 2 amps.

    My potential colo company says their r610 servers typically use 1 amp to 1.5 amps and yes it is also suggesting 2 amps. It says its r610 servers are using 7200 rpm drives and I have 5400 rpm drives. And so I might start with 1 amp and grow into 2...?

    That's not how it works.
    I assume your colo facility will plug in a kill-a-watt to determine max watts/amps at boot up of the server, then set your amps to that.

    They don't usually under estimate, because say the entire colo facility goes night night due to power issue, when all the servers all boot up around same time they don't want to exceed the 20amp+ breaker.

    So basically if your able to pass a kill-a-watt test @ being under 1amp then sure your golden.

    I may be wrong, so someone correct me if you've seen other practices at colos

    An R610 with dual processors boots to 110-130 watts (~1A) idle depending on config/processors. With higher end X-series processors, you will see 300-350 watt peak.

    Yeah this sounds like a 3 amp system. Buying a fast dual socket computer and then not having enough power to run it at full speed is a strange idea. As an aside, the reason this old hardware is so cheap is that newer stuff of comparable performance uses much less power.

    The question here is 1A @ how much volts. You can't calculate watts, without knowing the volts. 1A @240V, MIGHT be enough for idling system.

  • If you already have the server, and staying under 2 amps is more important than having it run at max speed, you might want to put a Kill-a-Watt on it and see whether you can get it down under 2A and still have adequate performance for what you need to do. What happens when you:

    • underclock the CPUs
    • install fewer RAM sticks, or maybe underclock the RAM if you need all of it
    • use 2 HDDs in RAID 1, if you don't need all 6 for the space
    • install SSD cache to reduce disk activity/power use, or replace all the HDDs with SSDs

    You might not end up with enough oomph for 10 VMs of the size it had before, but at least you'd have a hard comparison point with more expensive hardware at the same 2A limit. Trying for 1A might be too crazy, but would be interesting to know because so many places offer 1A service.

  • We have servers with 2x X5650, 12x 8G RAM, 4x 3.5 HDDs, 1 HBA and 2 PSUs. Should be pretty similar to your config.

    Idles at 180-220w.

    So, on 110v it's 2 amps idle, and up to 3-4 amps when booting up / under load.

    Thanked by 1yongsiklee
  • randvegetarandvegeta Member, Host Rep

    First, where is this? I assume in places like USA, power is 110-120v and places like EU will be 220 - 240v. This makes a huge difference as you're basically going to have half the power available on a 110 outlet.

    Assuming you are getting a 240v supply, 1amp is only 240watts.

    As has already been suggested, you should probably get 2amps because you need to make sure you have enough power for the initial boot-up, and for bursts of power. Bare in mind, your PSUs are rated for >700w, which means 3amps really.

    In reality, and idling box uses much less power than what they are rated for. My Xeon E3-1230v6 boxes idle at about 0.15 amps.

    You may be able to limit the power consumption of your server by doing the following:

    (In order of effectiveness)

    • Use High Efficiency PSUs
    • Under-clock your CPU
    • Use SSDs

    The most effective way to reduce power is to use a high efficiency PSU. When we first started out, we used just regular power supplies, which when idle are very very inefficient. They are not so bad when under load (typically around 70-75%), but when there is next to no load, the efficiency is atrocious (20-30%?). Switching to just the basic 80+ PSUs (not even the Bronze/Silver/Gold/Platinum rated ones) immediately reduced power consumption by half. For every PSU we replaced, we literally decreased our average power consumption for that server by 35 - 50 %. Don't even think about not buying an 80+ PSU! The savings in power meant we recouped our money in less than 4 months. Another thing to remember is to try and get appropriately sized PSUs. PSUs are most efficient at between 50 - 80% load. If you have a 700w PSU and your box peaks at 300w, then it will always operate at sub optimal efficiency. Having 2 PSUs makes it even less efficient... so you could also consider removing 1 PSU (but I would not really recommend that).

    Under-clocking your CPUs could significantly reduce power consumption, even at idle. Of course you lose performance, but you actually benefit in having a more stable system and much lower operating temperatures. The amount of savings varies greatly between different model CPUs, but it's generally around a 50% power reduction for every 25% reduction in clock speed. We had this old i7-3930k, which was overheating and crashing all the time. We under-clocked the CPU by 50%, and it idles at about half the power it used to, and the CPU typically stays between 30-40C and never over 50c. It's been rock solid since.

    Using SSDs uses marginally less power, but you get more performance, and disks are getting more and more affordable. So you may as well make the switch.

    *The server uses 120V.

    I just ordered Kill-O-Meter to see how my server uses electricity, and
    to experiment with reduced CPU speed and half the ram (32 gig is enough for now).

    I will replace HDDs with SSD drives and the current PSUs with 502W High Efficiency.

  • LyphiardLyphiard Member, Host Rep

    I host several dozen L5640 and X5675 servers and they draw between 100-270W depending on load with a single HDD/SSD in them. That being said, I'd recommend buying 3A power as that should suffice for continuous load.

    It's okay if you occasionally burst over 3A (at least with most providers). Power circuits are derated to 80% for a reason.

    Servers are normally built to handle 100 - 250v. What is important is what your provider gives you. If they give you 120v, then you need double the amperage.

    1amp @120v is only 120watts. No where near enough. Basically you need 6a if you're on a 120v circuit. 6 Amos on 120 is only 720watts, which is only just enough for the max rating of your power supplies.

    I got contacted by a colocation company, rather small, in my area, Northern Virginia, and they gave me
    2 AMPs (additional 1 AMP was given for free as I asked) and
    /29 network (5 usable IPs), and
    1 dedicated IP for my IPMI,
    30TB transfer on 1 Gig port per month, They guarantee
    99.99% uptime (100% uptime guarantee on their parent site).
    all for $50.00 per month. My server is
    Dell R610 with 2X5650 CPUs, 64 gig ram, 1tb Samsung SSD, 500 gb intel ssd, 5tb seagate hdd.
    The server is running fast and power is minimal. I am now running 4 VMs and the following is the network bench for one of my VMs:

    @randvegeta you’re comparing the most recent power saving tech with a scrap that should die long time ago. They are not able to go down with consumption at idle even close to the newest gens.

    Thank you for your info. That sounds right. I bought kill-o-meter and tested out at home before colo and it was running between 1 amp and 1.5 amp just like my current provider said. It hardly went over 2 AMP even with full tests of both CPUs utilizing close to 100%.

    I can also step up with more power, $15 per AMP when/if more power is needed.

    Another reason I went with the current provider is they only charge $5 for additional ip4 /29 and $10 for ip4 /28.

    Older gen CPUs cannot regulate their power consumption based on load very much.
    Modern CPUs will, while idling, take very little power.
