Endpoint power management: Energy savings through network monitoring?

Many network monitoring and security tools have been expanded to include power management and policy enforcement features. Find out what the Tolly Group learned when it tested Lumension’s endpoint power management software.

When it comes to IT power consumption management, many think of server virtualization and consolidation. But a number of IT organizations are still focused on the savings they can achieve with endpoint power management software. For networking teams, that’s crucial since endpoint power management tools are often only an evolution of the basic monitoring software they are already using to configure and patch systems across the network.

In fact, a number of companies that once focused solely on security monitoring, automated configuration and patching have expanded their tools to monitor endpoint and server activity in order to create and enforce power management policy that will power down machines when they are inactive and alert network managers when they are reaching power usage caps.

In January, The Tolly Group tested Lumension’s Endpoint Power Management software. Lumension’s power management package provides endpoint uptime reporting and can enforce policy by standardizing power settings across the network and automating standby and hibernation based on system activity. The tool is part of Lumension’s endpoint security system, which uses many of the same monitoring, reporting and automated management functions across diverse Windows systems on the network.

Tolly engineers built a microcosm of a corporate endpoint installation, using typical corporate desktop and laptop systems with mixed hardware configuration, operating systems and power management settings for the test environment. Test workload simulated a typical 9-hour workday with 6 hours active time and 3 hours idle time. Specifically engineers tested the monitoring, reporting, centralized management functions and overall energy savings.

Overall, the study found that implementing the endpoint power management software could result in an annual savings of $36,000 for an enterprise with 1,000 end-point systems. That meant an average savings of 266 kWh of energy per typical desktop.  Tolly’s report also indicates that the system integrated into existing IT security and management tools, limiting the amount of extra effort necessary for endpoint power management.

Tolly Group engineers outlined the full testing specs and results in the Lumension endpoint power management software report.
