Connecting the Pedestal to a Host System

This section illustrates how to connect four possible RA3000/Host configurations. The configurations are:

■Single host, single adapter configuration

■Single host, dual adapter/dual controller configuration

■Single host, single adapter/dual controller configuration (using a Y-cable)

■Dual host, single adapter/single controller configuration

NOTE: The following illustrations show the expansion pedestal option as part of the storage system installation. See Chapter 4 for a full description of the Expansion Pedestal.
