Abstract
This guide provides requirements and procedures for connecting an XP disk array or SVS 200 to a host system,
and for configuring the disk array for use with the Linux operating system. This document is intended for system
administrators, HP representatives, and authorized service providers who are involved in installing, configuring,
and operating the HP XP storage systems.
