Teak Technologies and Neterion Demonstrate 10-Gb Congestion-Free Ethernet Switching Solution for IBM BladeCenter at Next Generation Data Center Conference and Expo

10-Gb Congestion-Free Ethernet (CFE) switching solution for IBM BladeCenter is used to demonstrate in excess of a ten-fold improvement in end-to-end application-level latency, fairness, and full link utilization across multiple flows under transient and sustained network congestion

San Francisco, CA — August 7, 2007 — Blade.org members Teak Technologies and Neterion are demonstrating their 10-Gb Congestion-Free Ethernet switching solution for the IBM BladeCenter platform at the NGDC Conference and Expo here today.

The demonstration features an IBM BladeCenter-H chassis, two Teak 10-Gb CFE Switch Modules, and six Teak 10-Gb CFE Expansion Cards running on a mix of six AMD/Intel LS-21/HS-21 server blades. The two switch modules simulate a two-hop network. A modified ping-pong test running across multiple NetPIPE clients/servers simulates network congestion and displays application-level results graphically to highlight performance improvements under congestion. The results demonstrate in excess of a ten-fold improvement in end-to-end application-level latency, fairness, and full link utilization across multiple flows under transient and sustained network congestion.

The Teak 10-Gb CFE Expansion Card for the IBM BladeCenter integrates Neterion's advanced ASIC featured in the company's family of 10-GbE Xframe® V-NIC™ adapters featuring the Hyperframe™ suite of technologies designed to provide virtualization at the I/O level. The ASIC is based on a sophisticated state machine architecture that delivers the highest performance and reliability available, and as a result, enables complete end-to-end virtualized networks.

Teak's 10-Gb CFE switching solutions unlock the full promise of a loss-free Ethernet thereby transforming a data center network into a Congestion-Free Zone, and enabling performance that:

• improves upon comparable best-effort 10-GbE price/performance by up to 16x
• maximizes load-invariant, loss-free link utilization up to 100 percent
• reduces number of uplinks in multi-hop network configurations by up to 4x
• delivers SLA-driven, predictable application performance

"Congestion is way of life in bursty data center environments. Our solutions make it a non-issue and set the stage for Ethernet convergence on an end-to-end basis," said Sanjay Dua, chief marketing officer at Teak Technologies. "Legacy 1-GbE and 10-GbE networks are over-built and complex to deploy and maintain. They are also poor in containing congestion, which can bring network-bound applications to a virtual standstill thereby effectively denying service."

By way of contrast, Teak's 10-Gb Congestion-Free Ethernet switching solutions simplify a data center network by consolidating physical links by up to a factor of four and allowing customers to "right-size" their network. Physical links can be consolidated because Teak's switching solutions eliminate packet loss, even in bursty environments, thereby making each link more efficient and allowing it to carry more traffic while delivering highly predictable and reliable application service-levels.

Teak's 10-Gb Congestion-Free Ethernet switching solutions target mission-critical applications including programmatic trading of public investment securities, enterprise-class block-level storage connectivity, high-definition mixed-media content retrieval, caching, and transport in IP-TV and cable applications, and high performance compute and database clusters.

"We are pleased to have the opportunity to partner with Teak Technologies and provide virtualized I/O silicon for the industry's first 10-Gb CFE Expansion Card for the IBM BladeCenter platform," said Philippe Levy, vice president of marketing at Neterion. "This industry-leading combination of price, performance, and low latency for high performance storage and server connectivity applications is the latest example of 10-Gb/s Ethernet leading the fabric convergence movement in enterprise data centers."

"Teak is delivering working 10-Gb CFE switching solutions today as a winning alternative to those based on best-effort 10-GbE, said Bob Schack, vice president sales and business development at Teak Technologies. "Financial institutions, supercomputing facilities, enterprise data centers, broadcast and post-production facilities, IP video networks, and healthcare organizations that transmit data-rich medical imaging content are just a few examples of vertical industries that will welcome the price/performance advantage of this 10-Gb Congestion-Free Ethernet switching solution."
