Which of the following solutions satisfies a customer’s requirement for redundant FSPs in an E870 solution?

A.
Two E870 system nodes.

B.
One E870 system node and two System Control units.

C.
Two E870 system nodes and two System Control units.

D.
One E870 system node and one System Control unit.

Explanation:
The system control unit provides redundant system master clock and redundant system master Flexible
Service Processor (FSP) and support for the Operator Panel, the system VPD, and the base DVD. The system
control unit provides clock signals to the system nodes with semi-flexible connectors. A system control unit is
required for every E870 system.
