Data Center Designers In High Demand
Hugh Pickens writes "For years, data center designers have toiled in obscurity in the engine rooms of the digital economy, amid the racks of servers and storage devices that power everything from online videos to corporate e-mail systems but now people with the skills to design, build and run a data center that does not endanger the power grid are suddenly in demand. 'The data center energy problem is growing fast, and it has an economic importance that far outweighs the electricity use,' said Jonathan G. Koomey of Stanford University. 'So that explains why these data center people, who haven't gotten a lot of glory in their careers, are in the spotlight now.' The pace of the data center build-up is the result of the surging use of servers, which in the United States rose to 11.8 million in 2007, from 2.6 million a decade earlier. 'For years and years, the attitude was just buy it, install it and don't worry about it,' says Vernon Turner, an analyst for IDC. 'That led to all sorts of inefficiencies. Now, we're paying for that behavior.'" On a related note, an anonymous reader contributes this link to an interesting look at how a data center gets built.
That's probably part of the demand for the "data center in a box" concept. With a shortage of engineers to design centers it's an obvious move to try and start mass manufacturing them.
How many letters have you written to your congressman advocating that the government build a coal plant on your block? That's the fuel that America has the most of.

A designer needs to understand how cooling, power and building design affect each other. High density cooling and power management is a different beast. (And disaster management! Redundant power, fire suppression that won't destroy your computers, etc...)
I think that is the point here: Data centers have become large enough that you don't want to just stuff them into a random office building and hope everything will work out fine. Specialization is valuable in this case.
Yeah, except that mass-manufacturing data centers is like designing a 1999 Mazda or a 1956 Jaguar. There are so many factors that are changing regarding how data centers go together, that it's a moving target to get long-lasting designs. In the bad old days, you could get a 20 year life from a data center, and not a lot changed, year to year.
Now data centers can have lots of change-- as the servers themselves change along with equipment that's located in a data center. The -48vdc telephony equipment is now housed there, along with blade server chassis that breathe fire and suck power like an SUV-- let alone the heat generation problems.
Add in mandates of 5-9's availability (a new concept in the computer industry), earthquake, hurricane/tornado/flooding, power grid availability, the liablities of co-los, legal mandates and constraints, and data center design has become a discipline unto itself. It's not necessarily constrained by good personnel, rather it's constrained by the huge number of changes in the industry overall, and the numerous disciplines needed to bring asset life out of a data center investment.

While I admit that these datacentres are huge and get a lot of publicity, thus a lot of pressure to design right and "green" I don't think that level of advanced knowledge is typical for SMBs and even most non-IT centric businesses regardless of size.
In practice a company has a few servers and one or two system admins, then they grow, staff leaves, they start thinking about different technologies, required software changes etc. What they end up with is a few vendors servers, a few vendors disk arrays probably a few flavors of networking etc.
In short the "real world" problem for the majority of companies/sys-admins isn't the very academic concept of building a single purpose datacentre, but handling growth and change. I'm yet to see a good reference for how to handle this. At best I see vendors showing how great there new server/rack combination is in isolation, Another popular thing is the ever popular look how low our power needs per FLOP are for a data centre based on our products. Yeah like we are likely to use identical systems for databases as we do for LDAP, and the same one for a fileserver as we use for a MPI cluster.
Anyways, does anyone know a good reference to deal with these "real world" problems?
Data center employment often comes up in discussions of economic development. Many communities are eager to attract data center projects, but struggle to define the economic benefits of these facilities. Jobs have always been the primary benchmark by which economic development projects are measured. Incentive packages offered by state and local governments are often based on the number of full-time jobs created by a new business. And do data centers really hire locally, or do trained data center engineers migrate from other existing data center hubs? In some cases, local officials try to stipulate local hires, which is a sticky wicket.
