Extreme Networks introduces Direct Attach Architecture to increase data centre performance and reduce network tiers

Architecture brings virtual machine switching back into the network and out of the server

SYDNEY, April 20, 2010. Extreme Networks, Inc. (Nasdaq: EXTR) today announced its innovative ‘Direct Attach’ architecture for data centres, an architecture designed to bring virtual machine switching back into the network and out of the server.

Extreme Networks® Direct Attach™ data centre architecture is an evolutionary approach that allows virtual machines to be directly attached to the network without having to go through a full layer of software switching in the server. This approach to virtualised networks greatly simplifies management, monitoring and troubleshooting, while improving network performance in highly virtualised data centre environments.

“While embedded virtual switches have enabled early server virtualisation projects they can limit performance and increase complexity,” said Joe Skorupa, research vice president, data centre and transformation and security, at Gartner, Inc. “Emerging technologies like direct I/O and VEPA allow VM to VM switching to be implemented in hardware in the first physical switch, increasing performance and simplifying management.”

Extreme Networks Direct Attach architecture moves VM switching out of the server and into network switches, delivering wire-speed, network-based switching to VMs while dramatically reducing the number of managed switches through the elimination of the virtual switch layer.

In addition, Extreme Networks Direct Attach architecture significantly simplifies management and troubleshooting by exposing inter-VM traffic to traditional, mature and well-understood networking tools, such as ACLs, firewalls and IDS.

Extreme Networks Direct Attach architecture will interoperate with emerging IEEE 8021.Qbg, providing an easy and seamless migration path for organisations in addition to built-in investment protection.

“Extreme Networks Direct Attach architecture to virtual machine switching is a visionary step resulting in cost and performance benefits for the data centre,” said Shehzad Merchant, senior director of strategy for Extreme Networks. “Organisations can now transition their data centre from a physical to a virtual model without fear of being locked into any proprietary technology, realizing all the benefits of virtualisation, and eliminating some of the most painful objections.”

Extreme Networks Direct Attach will be made available through a licensable ExtremeXOS® software module, ranging across Extreme Networks’ portfolio of data centre switching products. This includes fixed configuration stackable Summit® switches, including the Summit X450, Summit X480, Summit X650 and the BlackDiamond® 8800 modular switching platform.

Extreme Networks Direct Attach architecture was named a Finalist for Best of Interop, recognising the best new products in the virtualisation category at Interop Las Vegas 2010.

Extreme Networks Direct Attach architecture is a critical element included in the company’s Four Pillar vision for the data centre, enabling enterprises, managed hosting providers and cloud providers to seamlessly migrate from a Physical network to a Virtual network to Cloud environments.

Availability Extreme Networks Direct Attach has a targeted release of third quarter CY 2010 via a licensable software module upgrade.
