Upper power & cooling limits in the Data Center

Joecampbell — Fri, 24 Sep 2010 14:04:18 +0000

Hi, do we still consider 85% as the recommended upper limit in the data centre with regards to power & cooling. I know this was a main driver from Gartner, but with increased efficiencies in M&E hardware has this view changed at all towards a higher recommended set point?

Thanks, Joe Campbell

Data center power related

A Data Center’s capacity is re-classified as 5 MW lower than it was previously, how to handle this situation? What all options do we have? Some high level points would be really helpful

Thank You!

Power for new Data Center with 7500sqft of technical area and will host high density, mainframe, storage and network infrastructure.

Mrjay — Wed, 23 Jun 2010 15:21:39 +0000

I am looking at the power requirements for a potential New Data Centre. The Centre is going going to be 7500sqft of technical area and will host high density, mainframe, storage and network infrastructure. I worked on 1500w per square metre. Do you think this is too much for a new centre that will need to last 15 years atleast. Our standard is to allow a maximum of 3 blade enclosures per rack in our primary site.

UPS redundancy vendor support

Data Center - Ask the Expert — Thu, 08 Apr 2010 18:27:46 +0000

We recently experienced a UPS failure and were on static bypass for more than 24 hours. During the static bypass, the load was directly fed by the State Water Electricity department and we were at their mercy. Had we lost power, all of our systems in the data center would have gone down. The problem that we had with our UPS was that some capacitors burned during operation and the circuitry switched to static bypass. Though our UPS is backed up by a generator, it was of no use since the UPS failed completely. I read an article where you talk about UPS redundancy. I’m interested to know more about this and if any of the UPS manufacturers support this type of UPS redundancy. Are there any case studies available, and which UPS vendors should I get in touch with for further details?[Br _extended=”true” />

Data center power and cooling ratio between allotment and use

Data Center - Ask the Expert — Thu, 25 Feb 2010 19:53:51 +0000

I work in the financial sector and was curious if you’ve noticed an average ratio between production space/power/cooling and what is set aside for DR space/power/cooling. i know there are a million variables to consider but was just interested if there was a generic 2:1 or 1:1 or 1.5:1 ratio you have observed over time.

Power usage effectiveness (PUE) tools in the data center

JennyMack — Thu, 04 Feb 2010 20:35:50 +0000

What power usage effectiveness (PUE) or efficiency estimator tools are you using for your data center? Have they exposed any particular places where you could improve? What type(s) of information do you wish you had more of?

Data center power design

Data Center - Ask the Expert — Mon, 27 Jul 2009 17:08:26 +0000

Our Data center has a 10,000A (6.5 MVA @220/380V, 60 Hz) rated capacity parallelling switchgear to supply critical load. However, the demand load is calculated @ 7.8 MVA. Our Electrical Consultant recommended a 4-2000KVA capacity prime generator, single paralleling digital switchgear(PSG). My question is how about splitting the 4 generating sets into two parts to cover the entire load of 7.8 MVA critical load and provide two PSG.
