Extreme Networks BlackDiamond 8810 Bests Competition By Delivering Enterprise-Class Features While Consuming Close to One-Half To One-Quarter of the Electrical Power

SANTA CLARA, Calif., March 3 /PRNewswire-FirstCall/ — Enterprises that are seeking “Green IT” solutions for the network, including the LAN backbone, aggregation portion and for data server farms, should review a recent test report showcasing how Extreme Networks, Inc.’s BlackDiamond(R) 8810 switch consumes less electrical power under various conditions and traffic loads when compared to modular LAN switching systems from Foundry Networks and Cisco.

Core Ethernet switches serve as the foundation for high speed data, bandwidth intensive enterprise applications, server farm aggregation and convergence. Operating on a 24×7 basis, the right core switches can support “Green” initiatives and cost savings through low power consumption, as electricity is saved from more efficient operation and design. This can result in annual cost savings while promoting a greener environment, with a reduced carbon footprint for organizations.

Recent tests recently performed by The Tolly Group clearly articulate the differences found with leading modular switches. The comprehensive power evaluation of switching systems demonstrates that Extreme Network(R) BlackDiamond(R) 8810 consumes 3.4X less power than Cisco’s Catalyst 6509 switch and 2X less than Foundry Networks Big Iron RX-16 switch, when similarly configured and passing data traffic. Over a period of five years using Extreme Networks solution, cost savings can be up to $5,000 per switch, based on the US national average price for commercial electricity, as reported November 2007. Extreme Networks provided the “greenest,” most energy efficient chassis of the three switches evaluated.

Enterprises are seeking power efficient network infrastructure to build their LAN backbones and distribution infrastructure as the cost and availability of power are becoming major considerations in the design of next generation network environments. Furthermore, IT managers expect and require that their drive for power-efficient infrastructure does not compromise on the critical features that are required within LAN switches. Extreme Networks solution portfolio can meet both needs.

The Extreme Networks solutions provide highly available, convergence-ready networks. Extreme Networks enhances its switching portfolio with an intelligent, edge to core modular operating system, ExtremeXOS, in addition to advanced traffic management functions providing Quality of Service (QoS) and integrated security functionality. This results in versatile, feature rich performance for the convergence of voice, video and data on a single network.

“Customers are seeking not only performance and reliability but also power efficient ‘Green’ solutions to underpin their network infrastructure, and as a result they turn to Extreme Networks,” said Paul Hooper, chief marketing officer for Extreme Networks. “The recent Tolly Group tests confirm how our BlackDiamond switch can deliver power efficiency compared to leading competitors. This helps enterprises meet their goal of a cost-effective, responsive and environment friendly network infrastructure.”
