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 andover two years of stress testing byvarious OEM test suites, with different operating systems. The robust N320E
delivers the most reliable performance and best value for 10GbE connectivity in the industry.
The adapter’s two ports and IEEE 802.3ad link aggregation/failover features are ideal for critical network applications that require redundancy
and high-availability capabilities.

Benefits
By using Chelsio’s N320E, enterprises can cost-effectively connect servers and storage systems directly to the 10GbE backbone
structure
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 – simplifying management and reducing costs for servers, rackspace, power consumption, and maintenance.

Applications with large data sets benefit from a high-speed distributed platform, including video renderingand distribution, data visualization such as
remote medical imaging and climatic modeling, and bioinformatics applications such as DNA sequencing.

Specifications
The dual-port N320E offers best-of-class performance and features,
including IP/UDP/TCP checksum and large send offload, rate control
and QoS, virtualization, and rule-basedtrafficsteering and filtering.
Third-Generation Protocol Offload Engine
The N320E employs Chelsio’s unique third-generation Terminator 3
ASIC, a high-performance, programmable protocol processor.
Terminator 3 processes all connections in a single datapath to deliver
line-rate 10Gbps performance with one connection, up to thousands
of connections. In contrast, competitive multi-RISC offload engines,
which rely on having enough connections to distribute their processing among parallel processors to achieve full performance, are ultimately limited by the performanceof each processor.
Robust, Proven Solution
Subjected to thousands of hours of compatibility testing, over two
years of stress testing by several OEM test suites and production
deployments in servers, storage systems and cluster computing,
Chelsio’s robust, stable protocol offload technology delivers proven
performance in a wide range of environments. The N320E is generations ahead of competing products.
Software Drivers
Chelsio offers a full suite of protocol software and drivers for Linux and
Windows with the N320E adapter.
