Input Power Supply Lines

Multiple power supply facilities in the building or UPS units are recommended for power supply redundancy.
When the ETERNUS DX Disk storage system power supply is redundantly configured, business can continue
even if one of the power lines fails.
Alternatively, optimal system design (including the server) may instead lead to the ETERNUS DX Disk storage
system being configured with only a single power supply facility or UPS unit. Which configuration is selected
will depend on system availability requirement considerations.
