1 Introduction
1.1 About this Guide
This guide describes how to install software and operate Alacritech
Accelerators on a Windows 2000, Windows XP or Windows Server
2003 system. Windows NT is not supported with this release, but
will continue to be supported under earlier releases with a major
number of 5.
1.1.1 Naming conventions
The general term Accelerator applies to all of the following
adapters, except where indicated:
•100x1 Single-Port Server and Storage Accelerator
(10/100BASE-T)
•100x2 Dual-Port Server and Storage Accelerator
(10/100BASE-T)
•100x4 Quad-Port Server and Storage Accelerator
(10/100BASE-T)
•Alacritech Single-Port Gigabit Accelerator
(10/100/1000BASE-T)
•Alacritech Single-Port Gigabit Accelerator (1000BASE-SX)
•Alacritech SES1001T iSCSI Accelerator
(10/100/1000BASE-T)
•Alacritech SES1001F iSCSI Accelerator (1000BASE-SX)
1-2 Alacritech Accelerator Users Guide
At times it will be necessary to differentiate between Network
Accelerators and Storage Accelerators. The specific term Network
Accelerator for this release applies to all of the following adapters:
•100x1 Single-Port Server and Storage Accelerator
(10/100BASE-T)
•100x2 Dual-Port Server and Storage Accelerator
(10/100BASE-T)
•100x4 Quad-Port Server and Storage Accelerator
(10/100BASE-T)
•Alacritech Single-Port Gigabit Accelerator
(10/100/1000BASE-T)
•Alacritech Single-Port Gigabit Accelerator (1000BASE-SX)
The specific term Storage Accelerator for this release applies to all
of the following adapters:
•Alacritech SES1001T iSCSI Accelerator
(10/100/1000BASE-T)
•Alacritech SES1001F iSCSI Accelerator (1000BASE-SX)
1.2 Description
Alacritech Accelerators are 10/100 or 10/100/1000 Mbps TCP
Offload Engine (TOE) network interface cards (TNICs) that employ
Alacritech’s SLIC (Session-Layer Interface Card) Technology.
Each Accelerator uses an innovative application-specific integrated
circuit (ASIC) for protocol processing. Alacritech Accelerators
operate with Windows 2000, Windows XP and all Windows Server
2003 operating systems.
SLIC Technologyincreases server performance and efficiency in
two specific ways:
Alacritech Accelerator Users Guide 1-3
■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.
SLIC Technology eliminates the burden of TCP/IP protocol
processing and data delivery on the host CPU. By offloading
protocol processing, SLIC Technology frees the CPU for
application processing, boosting both network and server
performance.
Alacritech Network Accelerators, offload TCP/IP protocol
processing and data delivery of all network traffic, including iSCSI.
Alacritech Storage Accelerators are designed for dedicated iSCSI
SANs, offloading TCP/IP protocol processing and data delivery of
iSCSI traffic exclusively, and providing standard NIC functionality
for all other network traffic through its interface.

2 Software Installation
2.1 Software Installation Overview
This chapter covers the installation of the software required for an
Alacritech Accelerator under Windows 2000, Windows XP and
Windows Server 2003. There may be different steps for each
Windows operating system, so follow each instruction carefully.
The following types of situations are covered during installation and
removal of Alacritech software:
■Installation of an Alacritech Accelerator during the
installation of the Windows operating system
■Installation of an Alacritech Accelerator into an existing
Windows system
■Updating the software for an existing Alacritech
Accelerator installation
■Uninstalling the Alacritech Accelerator software and
hardware
Note: Alacritech’s SLIC Technology requires the
installation of additional components not typically
required by a network adapter to support the TCP
offload capabilities of the Accelerator. All
installations must be done with the Alacritech
Setup utility.
2-2 Alacritech Accelerator Users Guide
2.2 Accelerator Software Installation
This section covers the procedures for installing the software
required for Alacritech Accelerators. Follow the appropriate
procedure for your type of installation.
Note: Running the Alacritech Setup program is the only
way to correctly initially install Alacritech
Accelerator drivers for Windows. Following initial
installation, the automated Add/Remove Hardware
Wizard will discover additional Accelerators.
Note: Alacritech Accelerator drivers cannot be installed
during the initial installation of Windows. If you
leave an Accelerator in your system through the
entire Windows installation process, the
automated Add/Remove Hardware Wizard will not
discover the Accelerator in your system on
subsequent reboots, since Alacritech drivers do
not ship with Windows.
2.2.1 Installation of an Accelerator without Port Aggregation
1. Insert your Alacritech Driver Installation CD into the
system.
2. In the Alacritech Accelerator Setup – Software
License Agreement window, click the Yes button if
you accept the license agreement.
