Question: What are your recommendations on fan controls and the best points to use for driving a feedback loop?

I have been reading quite a bit about Chatsworth for the past five months, and now we have an opportunity to install the cabinets, which is very exciting to be perfectly honest, but I wanted to run something by you.

I was thinking about the controls to implement for this project, I know from reading when there is a raised floor, the strategy can be as simple as pressure transducers ...

Question: My data center is a limited floor space (1600 sq) and running at 18 kW per cabinet. The cooling experts are indicating that a load of 18 kW would require about 2700 CFM to cool the equipment. They also indicate that max let through on a "Tate" floor tile is 1300 CFM. In this scenario we designed a wider cold aisle to accommodate a (2:1 - 2.5:1) floor tiles to enclosure ratio to meet the CFM required by the equipment.

This scenario leads to the potential of high density exceeding traditional cooling capabilities whether using CPI's Vertical Exhaust Duct or not, if there is not the floor space for additional perf tiles then your equipment cold air demand can potentially exceed the let through ratio. If true, would there be a watt per square foot - line/threshold, based on traditional cooling, raised floor height etc ...

Question: What floor tile perforation pattern (percentage open) do you recommend in data centers using cabinets with Vertical Exhaust Ducts?

Answer: If your data center uses CPI cabinets with Vertical Exhaust Ducts (VED) such at the F-Series TeraFrame Cabinet or the T-Series SteelFrame Cabinet, it ultimately does not matter where the air comes from or how it gets into the data center. However, since we have not addressed this particular subject before, your question represents an opportunity to talk further on the subject.

We recommend using one style of perforated tile through-out the space. Varying tile styles creates a mind-set for micro-managing the tile deployment, which is completely unnecessary ...

We often receive questions from folks in the industry about our products and solutions. Bill Watts, CPI Sr. Data Center Architect, responds to one.

Question: Is there a need to "balance" the air volume with the chimney solution when racks utilize different kW? Can I use chimneys on some cabinets and allow other cabinets to function without chimneys?

With all this talk about data center cooling, obviously where most of the power consumption is, what is being considered for smaller telecom rooms? IE, 1-4 Cisco 3750's in one TR. When you have 100 rooms of this size on a campus, power is still a concern. What mitigating factor, aside from turning down the A/C, is there available? Is anyone looking into it?
