Default Blade Servers in Data Centers

Has anyone had any experience with major Blade Servers installation in Data centers?
Do they really save space?
Don't they limit you bacuase of power and/or heat consumption?
Is the overall saving really significant compared with 1U servers?
Any particular brand you can recommend and why?

Thanks,
Eli

You can certainly save space, and power, using blade servers. Due to the consolidation of power supplies, sometimes disks, chassis cooling fans, and other things in a 1U server that produce waste heat, you'll typically find a power and heat savings vs 1U's of the same MHz. What you are not likely to find is a capital cost savings. The blades will cost more, but they may make up for themselves in long-term operating expense savings. It depends on your environment and cost structure.

Thanks for the explanation.
My follow-up question would be: have you had any experience with hosting providers? Aren't they limiting you with the number of machines you can stock because they result heat or power problem?

I do network engineering and operations for many hosting companies, so yes, I've got experience. We've encountered a few co-location facilities that have run out of HVAC plant capacity and had to upgrade in order to support additional heat load. Most places can get cold air to wherever it is needed as they size their chiller plant at the same time as planning for electrical load; and most facilities build the cost of cooling your equipment into the power circuits they sell you. E.g. if you buy 90A of branch circuits for a single cabinet, that is probably triple their average power density per sqft, but they are marking up the power so they can recover the cost of cooling as well.

One thing you should be concerned with at a small facility is, can they deliver that much power density as you grow? If they plan for the average customer to use 20 - 40A per rack and you come in needing ~100A for your high density servers, that may cause them to incur additional cost in pulling more branch circuits from a distribution panel. If you are a large customer in a small co-lo facility, they might even run out of power one day, and then you may be stuck in a place that can't grow with you.

Happy new year,

Blade servers are also more expensive than 1u servers as well. You also don't realize any savings in costs until 2-3 years later.

Is any special reason that blade servers are expensive? or only the power & space are good for long term.

Probably because blades are newer technology and probably cost a little more to make as well as the fact some company's no they can charge more for them.
