Forgive me for jumping in...I generally agree 100% with that
sentiment, but let's face the facts: The Ultra5/Ultra10 are the
"PC"
versions of UltraSPARC hardware. Everything about those two
machines
is far, far below Sun's general level of quality, from chassis
solidity to performance to overall feel.
i don't really agree.
i've been using ultra10's in server roles for many years now and
i've been very happy. i very quickly got rid of the onboard IDE
which is the main cause of slowness for these machines. it's
useful for attaching a flash to boot from is about all.
the chassis is pretty annoying, with the turn-me-upside-down
access. i've been tempted to put the (largely ATXv12) m/b
into a real case :-)
the u5/u10 also run a lot cooler and quiter than the other
models of which i've a few now, but the u10 is always on.
i have had one u10 m/b get fried one very hot weekend i was
not home, but spares are a good thing.
they are very PC like, but they still have OFW and still
seem mostly unencumbered by the dodgy hardware.
