Verari Systems' chief technology officer (CTO) David Driggers spoke to SearchDataCenter.com about how the company keeps blades cool, even in the hot aisle.What differentiates your systems from the competition?
David Driggers: Our blade architecture is very easy to integrate servers and storage into the same form factor.
Another big difference is the use of off-the-shelf components. It gives us a couple of advantages: When something changes, we're able to implement as soon as it happens. We're shipping [Intel's latest offering] Woodcrest the day it's available. It makes it much easier to come out with new products.
From what I've read, you're taking a different approach to cooling. Can you tell me about that?
Driggers: Our system can actually operate in the hot row. If you look at our rack, blades slide into both sides. There is no back or front. The cooling is all through the center. We draw air in through the base and accelerate it toward the top.
Normally, the servers at the base of the rack get all the cooling, and the ones at the top of the rack take what they can. We draw in more than 2,400 cubic feet per minute (CFM) of air. Each blade is getting 100 CFM. We don't have one blade getting 300 CFM and others getting less. Our blades have no cooling on the parts themselves. All of it is provided by the cabinet.
If you're in a raised floor environment, our installations have no problem being in a hot row. We don't draw air in from the ambient room unless we're in a solid floor environment.
If your rack is sucking in 2,400 CFM on a raised floor intake, does it create a problem for the surrounding equipment?
Driggers: No. It seems counterintuitive, but the blade rack creates a pressurized area on the floor. We actually improve poorly circulated areas. The only place that ends up changing is right near the CRAC units themselves.
Who do you see as your competition?
Driggers: IBM and HP are our two main competitors. We're right in their crosshairs and they're in ours.
What about Sun's plans to join the blade market?
Driggers: The market is very skeptical on Sun blades right now. Unless you're a traditional Sun house, you're not taking this very seriously. That's where Sun is seeing the growth in their x86 systems. I don't see Sun taking any business from HP, IBM, Dell or us for that matter.
[Driggers founded San Diego-based Verari 10 years ago. The company recently appointed former EMC-exec David Wright to CEO. Wright will take over the business functions, allowing Driggers to focus on the technology.]
