Uses dont seem to give that much credence either, according to GCG.
Our research clearly shows that customers just dont see much difference between the major x86 system manufacturers when it comes to energy usage, system density, or the vendors ability to maximize facilities usage for their customers, said Olds. Its difficult to make a name for yourself in a certain area when every other vendor is trying to stake out the exact same real estate.
The survey revealed that more than 60% of users see little, if any, difference in either the energy efficiency or density offered by systems from Dell, HP, IBM or Oracle. Among those who do see any kind of differentiation among the top OEMs, GCG found that HP and IBM tended to lead Dell and Oracle.
Every vendor is telling a story that emphasizes how many of their systems you can cram into a small area and how little juice they sip, said Olds.
Theres a lot of noise in the industry surrounding these issues, so customers are understandably confused. While these factors are becoming increasingly important in dictating purchasing decisions, its not going to be easy for any of the major vendors to differentiate themselves due to the rapid pace of development by their competitors.
This is borne out in a parallel field that of enterprise networking. A recent Gartner study, for example, delved into the approximate costs versus benefits of having an all-Cisco IT setup.
Gartner analyst Mark Fabbi believes that going all Cisco, all the time doesnt work to the customers advantage. He questions the common view that you can reduce networking TCO by having only Cisco networking equipment in house.
Power, cooling, and floor space consumption are an important factor in purchasing decisions now and will become more important in the future, said Olds.
In some cases, the duties are also being combined into one overall function. Moran said the big reason is money. As IT plays a greater role in the enterprise, its natural that the amount of space needed for the data center would rise.
åBut in many metropolitan areas, it can cost a fortune to buy the space needed to expand computing operations. åIn some cases, bringing in more power to support a mainframe or a huge bank of server blades can be a real problem.
You cant always ask the local utility to double your power requirements, said Moran. That simply may not be possible in some buildings.
The consequence is a lot more pressure on CIOs. Ten years back, energy costs didnt come out of the CIO budget. But Moran said that the days of someone else dealing with energy costs are disappearing. And management is telling those CIOs, much of the time, that they dont want to pay for a new data center they have to make do with what they have.
People care about things that are in their budgets, said Moran. CIOs have become very concerned about power and space planning as these areas can rapidly constrain their operations.
