Chapter 2. Installation overview This chapter lists the major considerations in the installation of a basic SAN configuration, the considerations for one sample installation and information for planning and installing devices in a rack. This information does not cover all possible installation scenarios. Example SAN solution configuration The solution used in this guide to illustrate the setup process is a direct attach multiple cluster configuration. It uses pre-installed mini-hubs as a starter solution with the option of adding additional FAStT500 mini-hubs and Fibre Channel switches or managed hubs for added host and drive scalability. Figure 7. Example SAN configuration Fibre Channel cable installation To avoid damage to your fiber-optic cables, follow these guidelines: v Do not route the cable along a folding cable management arm. v When attaching cable to a device on slide rails, leave enough slack in the cable so that it does not bend to a radius smaller than six inches when extended or become pinched when retracted. v Route the cable away from places where it can snag other devices in the rack. v Do not over-tighten the cable ties or bend the cables to a radius smaller than six inches. v Do not put excess weight on the cable at the connection point. © Copyright IBM Corp. 2001 15
