Alacritech Accelerator Hardware Installation Guide 1-1
1 Introduction
This guide describes how to install Alacritech

Accelerators in servers with PCI-X or
PCI Express (PCIe) architecture.
1.1 Description
Alacritech Scalable Network Accelerators (SNAs) are single-port or multi-port network
interface cards (NICs) that employ Alacritech’s Dynamic TCP Offload technology,
which uses an innovative application-specific integrated circuit (ASIC) for protocol
processing.
The Dynamic TCP Offload increases server performance and efficiency in two specific
ways:
• TCP/IP Protocol processing is offloaded onto the Accelerator, freeing the CPU
for application processing and maximizing throughput
• A unique ASIC utilizes an Internet Protocol Processor (IPP), optimized for
TCP/IP protocol processing, which delivers faster performance than general
purpose CPUs
Dynamic TCP Offload eliminates the burden of TCP/IP protocol processing on the host
CPU. With protocol processing offloaded onto the Accelerator, the CPU is freed for
application processing, boosting both network and server performance.
1.2 Supported Accelerators
This guide covers the following Accelerators:
• SEN3000 Series 10 Gigabit Accelerators
• SEN2000 and SEN2100 Series Gigabit Accelerators
