Hardware Layout

Protection against power supply problems or other disasters at the installation site requires that hardware units be physically installed in
different sites.
Accordingly, install duplicate hardware units in different buildings, on different floors, or in different racks.
Whether management servers are also installed at different sites depends on whether redundancy is used.
The following figure shows a layout in which management server redundancy is not used.

ETERNUS AF/DX
The business servers, Fibre Channel switches, and storage systems are installed in different buildings, on different floors, or in different racks.
By clustering the business servers and the storage systems between different sites, business continuity can be maintained in the event of a
problem that affects the entire site.
Install the management server at a different site to prevent it from being affected by the problems in the business servers and storage
systems.
