Slightly OT: Calculating HVAC requirements for server rooms
by Mike Lyon 04 May '09

04 May '09

Hello All, I am curious what formulas/equations folks use to figure out required cooling for small datacenters in offices. The variables I am using are the size of the room, the total amount of power available for usage and the lightning. Specifically, I am using the guide posted at: http://www.openxtra.co.uk/articles/calculating-heat-load Any other recommendations or suggestions from those folks that have done this before? Thank You in advance. Cheers, Mike

Just knowing your spacing and were to places perforated tiles is very helpful in maxmizing air and not shortcycling it..

That's not the hard part. Some comments: > I am curious what formulas/equations folks use to figure out required > cooling for small datacenters in offices. The simplest equation to use assumes that you know how much power is going into the room. Btu/hr = watts * 3.412 This further assumes that a typical IT load is very inefficient (which they are).. meaning that, for every watt that goes to a computer / server / router, a significant portion is converted to heat (we assume 100% for design purposes). So, if you have a datacenter consuming 100kw, you'd need 341,200 btu/hr of cooling, or 28 tons of HVAC. Of course, there are other issues (like leakage, windows, doors, humans, lights) but these tend to be a little bit of line noise in a modern datacenter. Also outside environment (is this Quebec or is this Cuba), insulation, design delivery temperature, humidity requirements -- all play a part. > Translation: Hire a f***ing professional. > > And that's exactly what you need to do. Qualified HVAC installers Two comments on this... first of all, the last thing you want is an HVAC 'installer' to design your HVAC system in a datacenter. Secondly, if you find an HVAC engineer who *really* knows datacenter dynamics, that could be a help. But, frankly, there aren't a lot of them. If you need some help with this, let me know. There are a significant amount of questions that need to be asked to give a qualified answer. The cooling capacity question is secondary to the delivery and extraction method. I also submit that any good datacenter operator, who has had years of experience of trial and error, years of engineers who say they know something and don't, and had scores of contractors who say they know something and don't, is in a much better position to talk about this than a PE who designs comfort cooling systems.

In modern data Centers drop ceiling is installed. The reason being you can create a AIR plenum. If your not going to have a air plenum then you should not have a drop ceiling. If you look at the in the link below you will see were the red arrows are thats were you would installed drop ceiling perferated tiles. Then the crack you will have a housing that sits ontop of the crack unit connected the ceiling to it and pulls air in.

They hooked up the redundant systems, but didn't bother with much else. The return feed is below the units pulling ambient air, and the cold air is injected 15+ feet above the isle behind the servers, intermixing with the hot air as it rises up the wall. At least it works, but it could be better and changes will need to be made before I can reach 50% capacity in the racks.

how to fix incorrect GeoIP data?
by Chuck Anderson 01 May '09

01 May '09

I have a customer who received a new assignment from ARIN, but the GeoIP data is returning Canada rather than the US as the location of the IP prefix. Google redirects to www.google.ca and some other sites aren't working correctly because they expect a US IP. Does anyone have any advice on how to update the GeoIP and other similar databases? Thanks.

Beware surfers: cyberspace is filling up
by J.D. Falk 30 Apr '09

30 Apr '09

'Experts predict that consumer demand, already growing at 60 per cent a year, will start to exceed supply from as early as next year because of more people working online and the soaring popularity of bandwidth-hungry websites such as YouTube and services such as the BBC’s iPlayer. It will initially lead to computers being disrupted and going offline for several minutes at a time. From 2012, however, PCs and laptops are likely to operate at a much reduced speed, rendering the internet an “unreliable toy”.' http://technology.timesonline.co.uk/tol/news/tech_and_web/the_web/article61… (I don't even know where to start.) -- J.D.
