Introduction to Data Replication Manager 1–7
Fully-Redundant Power—Optional
Fully-redundant power is an optional feature designed to offer a more secure source of
power in the event that one or more units should fail. If less than five power components
are operational, then the entire cabinet will shut down. This requires three additional
power supplies and one additional AC power controller that plugs into one additional
PDU. These additional components must be supplied for each BA370 enclosure. See the
RA8000 and ESA12000 Storage Subsystems User’s Guide for more details about power
supply Storage Building Blocks (SSBs).
Host Bus Adapter
The host bus adapters are inserted into the available slots on the host computer’s PCI Bus.
A Fibre Channel connection is made by inserting a multi-mode fiber optic cable between
each adapter and an individual port on the Fibre Channel switch. See the KGPSA
PCI-to-Fibre Channel Host Adapter guide for more information.
