whether a data center should be outsourced or managed in house. Is there a point, i.e. power, space, cooling, security, personnel, etc. that dictate whether or not you build/expand a data center or look to outsourcing to a co-location provider?
The central issue faced by businesses considering in-house... More... Jan 27, 2006
trend in data center business? I think there are really two important trends. One is the ability to mirror data over greater distances, making it more practical to construct and operate true backup data centers farther apart than ever before. But I believe your question has more to do with the...

the TIA 942 data center standard. I never recommend people plan on staying with 10/100 due to the fact that our applications and data stores grow constantly. Ideally you want your cabling to support two to three iterations of active electronics. It is expensive to rip out and reinstall cable as...

have in my data center? Absolutely NOT. The major players all have supplemental cooling that will work with other manufacturers' cooling because of the way they are deployed. The key word here is supplemental. If the cooling is in a cabinet, mounted in the ceiling or is a water-cooled cabinet, it can...

Most people today install 50 micron laser optimized fiber in the data center. It will support 10 gigabit and is fully backwards compatible with other multimode connections. Fiber... More... Mar 3, 2006
total costs?
Data center design is complicated by rapid changes in technology and uncertainty about future capacity requirements. Your question implies you are already thinking beyond initial system costs, and considering total cost of ownership, which is wise. Energy costs and... More... Aug 4, 2005
height in a data center? The higher the better. The space above the cabinets accumulates rising heat and minimizes its mixing with cold air. This improves air conditioning efficiency. Obviously, it also provides space for overhead cable trays and good lighting. We generally like to see at least...

Raised floor or attached cabinets to the slab?
Hot aisle/cold aisle with forced enclosures on hot aisle or not?
This will be an approximately 7,200-sq. ft data center. There will be approximately... More... Oct 8, 2007

for a small data center? Our data center currently consists of seven racks. I doubt you will find anyone, other than a fire suppression system salesperson, who will tell you there is a "correct" solution for any data center. The liabilities if something unpredictable happens in a fire are just too...

now. The data center that is at my current job
is dated. I believe it was put in the 60's. Now, since it is dated, my
objective is to get it renovated. The problem is accounting wants
justification for that to happen. The first route I was taking was that the
servers are running too hot. In two of the racks...

an interior data center, but since most people call for it, I can at least tell you what we recommend and why, as well as give you a little of the "debate" thinking.
First of all, the purpose of a vapor barrier is to keep condensation out of insulation, since moisture reduces the insulating value, and to keep... More... Nov 30, 2005
for a new data center that is cost effective for at least another 10 years? If not, what are the major factors that we need to put into consideration with the new and future server technology in mind? A book could probably be written on this, and it is one of the most difficult things we do in...

of your data center for air in the process. Even increasing aisle widths doesn't do it. There are really only three ways to solve the problem: Put only one Blade Chassis in a cabinet and spread them out so the load is distributed across a larger part of the data center. This is what most people are...

in the data center.
Lets take these one at a time. Raised access flooring is generally used to provide both a place for the quantity of power and communications cable necessary to a data center, and a plenum to convey cool air to the cabinets. But in order to be useful for either, it needs to be high... More... Jul 18, 2005

data center using only conventional CRAC Units – and that assumes a raised floor of 24-inches or more in height, which is unlikely in most existing rooms. If overhead cooling is to be used, then it will be necessary to use a significant amount of duct work to properly channel both the...

cable your data center to TIA-942, which suggests that you run your horizontal and vertical cabling to accommodate growth so that you don't have to revisit them. Cabling is a very small part of your overall network costs (5% to 7%), so this should not be your prime consideration. But in a typical scenario...

keep the data center floor from being truly redundant. That is to say, if one of the air units failed, the return air from the hot aisle would not be properly cooled for re-use.
