To meet the challenges of collaboration over wide area networks (WANs) and dynamic web services, enterprise IT managers have deployed a range of network- edge appliances for real-time traffic analysis and management, load balancing, and optimized application delivery across WANs. From a network performance viewpoint, such network-edge devices require network require very high bandwidth and minimum latency. Moreover, because these appliances are in-line with the critical path, they must be able to fail safely; otherwise, a failure or instability could bring down the entire network.
To address these requirements, Chelsio has designed a family of 10GbE and GbE bypass server adapters specifically for WAN optimization, load-balancing, traffic management and other networking appliances at the network edge. Chelsio's 10GbE B320E adapters deliver the highest performance bypass adapter solution available in the industry.
Bypass mode ensures business continuity
To help maintain business continuity in the event of a failure, B320E provides a programmable bypass mode. The bypass mode automatically activates upon programmed detection of an appliance power- down, BIOS boot, or an OS or application program failure. When a detected failure occurs, mechanical relays switch the network traffic so it flows out the second port of the pair on the adapter, bypassing the problem server appliance and maintaining business continuity.
Integrated external switch fabric
The integrated external switch can classify flows, redirect and reject traffic without host intervention such that the host listens on desired flows only. This selective bypass can be enabled on a per packet basis at line rate.
Fully featured server adapter
The dual-port 10GbE B320E offers best-of-class performance and networking features, including IP/UDP/TCP checksum and large send offload, rate control and Quality of Service (QoS), and rule-based traffic steering and filtering.
Third-generation protocol offload engineProduct Highlights
The B320E employs Chelsio's unique third-generation Terminator 3 ASIC, a high-performance, programmable protocol processor. Terminator 3 processes all connections in a single data path to deliver line-rate 10Gbps performance with one connection, up to thousands of connections.
