Hows this for a simple way to trim your IT budget: use virtualization to reduce the number of servers in your data center and get your utility to pay for up to 50% of the projects cost? Utilities like Pacific Gas and Electric (PG&E) are dangling rebates in front of their customers to help sell them on the merits of going virtual.
The typical rebate is about $158 per each server removed, said Mark Bramfitt, PG&Es principal program manager, Customer Energy Efficiency. The energy savings is then roughly $200 to $300 per server, per year range, and thats just for powering the server. When you factor in the reduced cost of air conditioning, you could easily double that.
Air conditioning is where this all started, in fact. Cooling is one of the biggest expenses in the average data center, and PG&E initially had incentives in place to make data center cooling more efficient. We realized we were missing the boat on the IT side, which, in a well run data center, is half of the energy use, he said.
As PG&E sought ways to make the IT part of the data center equation more efficient, they quickly latched on to virtualization as the technology with the most promise. An incentive program was developed with consultation from VMware. It wasnt a formal partnership, Bramfitt said. One of their sales reps came to us and asked whether virtualization would be appropriate for our incentive programs. It was as simple as that.
Unfortunately, customers werent so easily sold. The program was very publicly launched in November 2006 at VMworld, but few customers signed up. In the fall of 2007, PG&E had paid rebates for only four projects.
PG&E responded by streamlining the program, simplifying the application process, and in the meantime, virtualization as a technology has had more time to mature. The program itself is straightforward. Customers go through an application process that provides details on their current facilities, specifics of the project and predicted energy savings. PG&E has a calculation formula that customers can use to forecast their savings. After implementation, customers then apply for their rebates.
Today, PG&E has more than 125 customers involved in the program and other utilities are following suit. (For a list of participating utilities, go to: http://www.vmware.com/solutions/consolidation/green/pge.html.)
VMware Enrolls Its Own
Programs like these are a boon to technology vendors, of course. The rebate covers a good chunk of the cost of the virtualization project, yet the vendor doesnt have to pay the rebate.
Utilities across the country are offering incentives to customers who can demonstrate energy reduction in their data centers by doing server consolidation with VMware, said Josh Leslie, VMwares director of alliances.
(We should note here that the utility company rebates are for any virtualization project that consolidates servers, whether these use VMwares technology or not.) Leslie noted that server consolidation is starting to be seen as a centerpiece of green data center initiatives.
VMware has worked to enroll more than 30 of its own customers into these programs, with another 25 or so currently going through the incentive application process. We also know that many other (virtualization projects) have been submitted directly to the power companies, without VMwares assistance, Leslie said.
Leslie confirmed that the incentive programs were helping VMware sales. In tough economic times, upfront costs can stall projects even if the technology will pay for itself over time. Trimming those upfront costs cant help but boost sales. These programs can offset the cost of a VMware project by at least 20%, he said.
Autodesk, USPS Save
PG&E customers whove participated include the United States Postal Service in the
Autodesk, on the other hand, made much more significant energy reductions. Autodesks data centers were using more than 15 times as much energy per square foot as typical office space. Its largest
In the initial stage of the project, the company reduced the number of servers in this data center from 150 to seven. By the end of 2007, Autodesk had virtualized 350 total servers, eliminated the need to purchase about 90 new ones and pinpointed 40 other servers that will be consolidated in the future.
One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
