CPU

Table 2.3
The CPU is an IPF processor. The reliability, availability, and serviceability (RAS)
function is enhanced by the error detection and correction function incorporated
for cache memory, etc. This improves business continuity.
The IPF improves performance because its 64-bit processors use an expanded
memory address space and have higher computing speeds.
One to four CPUs can be mounted on one SB.
