Data centers consume a great deal of
power, so one of the most effective things you can do to reduce your data center’s costs is to increase its energy efficiency. Building and certifying a green data center can be well worth it if you’re embarking upon new construction, but most of us are working with existing networks and are looking for ways to make existing networks more energy efficient. Fortunately, there are ways to make your data network greener with minimal disruptions to its operation.
1. Look for Energy-Efficient Ethernet (EEE) devices.
When you add new equipment, look for Ethernet devices that meet the 802.3az Energy-Efficient Ethernet standard. This new standard can reduce power consumption by 50% or more by scaling down power during periods of low data activity. These new energy-efficient switches, NICs, and routers are totally backwards compatible with older equipment, so they work seamlessly.
2. Take advantage of remote power management.
Remote power managers are devices that enable you to remotely power down unused equipment over your network—for instance, internal company servers during nights and weekends—saving both the power used to run the equipment and the associated cooling costs. Set the power manager to automatically shut down and restart at pre-set intervals or power down manually; either way you save energy.
Most remote power managers also monitor power consumption, alert you when circuit breakers are tripped, and enable you to reboot network devices, making them an invaluable addition to a network manager’s arsenal.
