Organization of This Guide Table of Contents This guide is the primary reference and operation guide for Alacritech Accelerators and contains the following sections: 1 Chapter 1 - Introduction provides a general introduction to Alacritech Accelerators and the SLIC Technology on which they are based. 2 3 1.1 1.
• SEN2102EF Dual-Port Accelerator (1000Base-SX) iSCSI Controllers: 1 Introduction 1.1 About this Guide This guide describes how to install Release 9 software and operate Alacritech Accelerators on a Windows Server 2003-based system or a Windows XP Professional x64 Edition-based system that uses the Microsoft Windows Server 2003 Scalable Networking Pack.
• 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 on the host CPU. By offloading protocol processing, SLIC Technology frees the CPU for application processing, boosting both network and server performance.
Note: The Microsoft Scalable Networking Pack must be installed prior to installing Alacritech software. If Scalable Networking Pack is not installed, you will get the following popup and be unable to complete the installation. 2 Software Installation 2.1 Software Installation Overview This chapter covers the installation of the software required for an Accelerator under Windows Server 2003 or Windows XP Professional x64 Edition.
