Teak Technologies Raises 10GE Performance Bar to Unmatched Level

Market Wire, March, 2008

As yet another industry-first milestone, Teak Technologies recently demonstrated unmatched throughput performance from its AZ-10GE switching solution for IBM BladeCenter running the Reuters Market Data System (RMDS) application suite used by securities firms worldwide to supply real-time data to traders and automated trading applications.

"We recently completed Phase-1 tests on Teak's equipment using the Reuters Market Data System," said Peter Lankford, director of the Securities Technology Analysis Center (STAC®). "Our testing focused on two objectives: (1) stress test the equipment to determine peak sustained link utilization level with Teak's hardware-based Acceleration Zone (AZ-10GE) algorithms and, (2) establish the baseline native 10GE latency with Teak's Acceleration Zone (AZ-10GE) algorithms disabled and with no assistance from client-side acceleration algorithms such as TOE, iWARP, or RDMA. Our tests found that Teak's solution improved link utilization from 7.7Gbps to 9.6Gbps in the AZ-10GE mode and delivered mean latency of less than one millisecond at up to 450,000 updates per second in native 10GE mode with no client-side acceleration.

"10GE switch vendors claim to deliver line-rate performance with zero packet loss across all packet sizes. However, such claims assume well-behaved traffic flows and speak nothing of their number, arrival characteristics, or port oversubscription rates," said Sanjay Dua, chief marketing officer at Teak Technologies. "By way of contrast, AZ-10GE solutions allow applications and networks to work as an efficient closed-loop system where traffic flows unimpeded at line rate without incurring packet loss even in adverse environments. AZ-10GE algorithms self-adjust to maintain peak performance at all times while adapting to changes in traffic mix/volume, round-trip time (RTT), network topology, and equipment add/moves. In a historical first, Teak's AZ-10GE technology allows Ethernet to operate optimally and reliably with full link utilization, no packet loss, and low latency while ensuring high levels of application availability and predictability."
