You follow up your first step with a series of efforts that continue to drive efficiencies in the IT environment. One is to cull the remaining services you are delivering by eliminating those that have a cost that is disproportionate to the value they contribute. To do that, you need cost data that helps you and business managers make wiser choices about the services IT delivers.
When you have cost information, for example, you can demonstrate to your business users how much IT must charge for each service. Then, based on that charge, you can ask if they want to continue receiving that service or terminate it.
Another action is the consolidation of workloads onto a smaller number of servers. This further reduces the number of servers, which naturally brings down energy consumption. It also increases resource utilization by taking advantage of surplus capacity. A key success factor in server consolidation is effective planning. An important aspect of planning is to understand how much server capacity you have and how that capacity can be best utilized to deliver business services at required performance levels. The goal is to strike the optimum balance between capacity utilization and performance.
Virtualization is another method of shrinking the number of physical servers. Solutions are available that enable you to leverage the capacity information you have gathered to move forward in your consolidation and virtualization initiatives. With these solutions, you can analyze current usage profiles to determine a more efficient resource allocation-one with a smaller processing footprint that still enables you to meet the usage profile.
Finally, you can look beyond the data center in your energy conservation efforts. The average PC consumes much more energy than a television set. Sleep mode does little to reduce the amount of energy these machines burn up. Look at ways to power them down when they are not in use without jeopardizing your ability to manage them. Software is available to help you keep them patched, even if they aren't on all the time.
