Cisco says the company complements its existing services portfolio by "using the capabilities of the network to gain visibility into and control energy usage across global IT environments," a pressing need as companies grow and scale globally.
The smaller company also complements Cisco's Energy Wise product, which allows IT managers to manage energy usage across the enterprise network without requiring device-side agents or special configurations.
"It extends our 'Internet of Things' capabilities," Cisco Industry Solutions SVP Faiyaz Shahpurwala said in a statement. "JouleX's cloud-enabled, agent-less architecture will allow our partners and customers to quickly deploy this solution at scale in addressing their IT energy management needs."
JouleX employees will be integrated into the Connected Energy Solutions team within Cisco's Industry Solutions Group, reporting to general manager David Goddard.
The acquisition is expected to close in the fourth quarter of fiscal year 2013.
