5.3 Installing Host Interfaces
Optional host interfaces can be installed while the ETERNUS DX Disk storage system is running without
affecting the system.
5.3.1 Installation Rules for Host Interfaces
This section explains the installation rules for host interfaces.
One or two host interfaces that have two host interface ports can be installed for each controller.
Figure 5.3
and Figure 5.4 show the installation diagrams for host interfaces.
Install the host interfaces for CA#0 first, and then CA#1. Host interfaces that have different interfaces can be
installed in CA#0 and CA#1.
For a dual-controller type, the configuration is the same for Controller 0 (CM#0) and Controller 1 (CM#1).
■ For a single-controller type
