10GbE Server Adapter

TCP/IP • Storage • Computing Applications

CHELSIO’S N320E Server Adapter i s a d u a l - p o r t 1 0 G i g a b i t Ethernet adapter with PCI Express host bus interface for servers and storage systems. The cost-effective N320E provides higher bandwidth for end nodes for organizations using 10 Gigabit Ethernet in the data center with advanced stateless offload. The N320E represents the third generation of Chelsio’s server adapters. Easy to deploy, it comes complete with turn-key drivers for

major server operating systems.

Chelsio’s 10 Gigabit Ethernet adapters have been subjected to thousands of hours of compatibility testing and over two years of stress testing by vari- ous OEM test suites, with different operating systems. The robust N320E delivers the most reliable performance and best value for 10GbE connec- tivity in the industry.

The adapter’s two ports and IEEE 802.3ad link aggregation/failover fea- tures are ideal for critical network applications that require redundancy and high-availability capabilities.

Benefits

By using Chelsio’s N320E, enterprises can cost-effectively connect serv- ers and storage systems directly to the 10GbE backbone switching infra- structure over CX4 copper cabling.

As an upgrade or an alternative to aggregated Gigabit Ethernet links, 10GbE boosts connection bandwidth and simplifies cabling, installation, and maintenance. The N320E also provides additional bandwidth needed to consolidate server functions on fewer, more powerful systems – simpli- fying management and reducing costs for servers, rackspace, power con- sumption, and maintenance.

Applications with large data sets benefit from a high-speed distributed plat- form, including video rendering and distribution, data visualization such as remote medical imaging and climatic modeling, and bioinformatics appli- cations such as DNA sequencing.
