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.
Consider the bus repeater circuit built into every Sun Fire V440 server. This circuit
interconnects all CPUs and high-speed I/O interfaces (see
adapting its communications depending on how many CPU modules are present.
This sophisticated high-speed interconnect represents just one facet of the Sun Fire
V440 server's advanced architecture.
What It Does
Tests system components,
focusing on peripherals and
I/O devices
Display various kinds of system
information
Display various kinds of system
information
Exercises and stresses the system,
running tests in parallel
Monitors both hardware
environmental conditions and
software performance of multiple
systems. Generates alerts for
various conditions
Exercises an operational system
by running sequential tests. Also
reports failed field-replaceable
units (FRUs)
Accessibility and Availability
Can be run automatically at
startup, but the default is
no diagnostics. Can also be
run interactively. Available
when the operating system
is not running
Available when the
operating system is not
running
