Ethernet Switches support virtualized environments.

Press Release Summary:

BlackDiamond® and Summit® switches, running ExtremeXOS® operating system, support M-LAG Direct Attach data center architecture, which simplifies network design and scales performance. Combination of Direct Attach(TM) Virtual Machine (VM) switching and Multi-System Link Aggregation (M-LAG) supports virtualization and VM mobility associated with shared and dynamic resources in private and public cloud architectures.

Original Press Release:

Extreme Networks Reduces Data Center Complexity with Enhanced Network Architecture

M-LAG Direct Attach architecture eliminates outdated Spanning Tree designs and combines network scale with simplicity to enable highly virtualized cloud architectures

SANTA CLARA, Calif. -- Extreme Networks, Inc., (Nasdaq: EXTR) today announced an enhanced network architecture aimed at boosting performance in next-generation data centers and clouds by combining its Direct Attach((TM)) Virtual Machine (VM) switching with Multi-System Link Aggregation (M-LAG) to enable a new M-LAG Direct Attach architecture that addresses high-performance switching for virtualized environments.

With the emergence of private and public cloud architectures, the networking infrastructure required to support virtualization and the VM mobility associated with shared and dynamic cloud-based resources has become overly complex due to outmoded network designs based on Spanning Tree. Extreme Networks M-LAG Direct Attach architecture addresses this complexity by significantly simplifying network design and scaling performance.

"Extreme Networks M-LAG Direct Attach data center architecture will greatly help IP-Only to scale services while ensuring redundancy within the network and data center," said Magnus Oberg, CEO for IP-Only, a premier service provider in Sweden. "With this ExtremeXOS® feature, we decrease complexity in the network compared to other solutions and scale to meet the needs of more demanding virtualized services."

"Integrating the M-LAG Direct Attach architecture with Extreme Networks' data center portfolio serves as an important evolution of our Four Pillar data center strategy for migrating networks from physical to virtual to cloud," said Shehzad Merchant, senior director of strategy for Extreme Networks. "For the majority of virtualized data center architectures, the M-LAG Direct Attach architecture eliminates the drawbacks of Spanning Tree while providing the benefits of TRILL (Transparent Interconnect of Lots of Links) without having complete disruption to the network and enormous capital expense."

With its high-performance data center solutions, the BlackDiamond® and Summit® switches running the ExtremeXOS® operating system, Extreme Networks now delivers a doubling of performance compared to traditional Spanning Tree architectures and provides a simpler, more cost-effective solution over pre-standard TRILL implementations - all of which would require a rip-and-replace of the existing network. More information about Extreme Networks M-LAG Direct Attach architecture is available with its white paper.

With the release of ExtremeXOS version 12.5, Extreme Networks enables software-loadable support for Direct Attach architecture, network-level support of Virtual Ethernet Port Aggregator (VEPA), and M-LAG across its portfolio of high-performance BlackDiamond modular switches and Summit fixed stackable switches. Extreme Networks Direct Attach architecture enables the removal of virtual switches from the network, increasing performance, reducing cost and greatly simplifying management of the virtualized environment.
