Which component of the POWER8 system architecture provides improved RAS capabilities relative to
POWER7 system architecture?

A.
PCIe Gen3

B.
CDIMMs

C.
N+1 Power Supplies

D.
CAPI

Explanation:
CAPI on POWER8 systems provides a high-performance solution for the implementation of software-specific,
computation-heavy algorithms on an FPGA. This innovation can replace either application programs running on
a core or custom acceleration implementations attached via I/O. CAPI removes the overhead and complexity of
the I/O subsystem, allowing an accelerator to operate as an extention of an application. The IBM solution
enables higher system performance with a much smaller programming investment, allowing heterogeneous
computing to be successful across a much broader range of applications.
