Specifications; Software Drivers - Chelsio Communications N320E-CXA Specifications

Fully Featured Server Adapter
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-based traffic steering 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 process-
ing among parallel processors to achieve full performance, are ulti-
mately limited by the performance of 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 genera-
tions ahead of competing products.

Software Drivers

Chelsio offers a full suite of protocol software and drivers for Linux and
Windows with the N320E adapter.
