Diagnostic Tools

Why are there so many different diagnostic tools?

There are a number of reasons for the lack of a single all-in-one diagnostic test,
starting with the complexity of the server systems.

Consider the data bus built into every Sun Fire V490 server. This bus features a five-
way switch called a CDX that interconnects all processors and high-speed I/O
interfaces (see

FIGURE 6-1

). This data switch enables multiple simultaneous transfers

over its private data paths. This sophisticated high-speed interconnect represents
just one facet of the Sun Fire V490 server’s advanced architecture.
