Stephen Lee,
To tell you the truth, sun 4500 is the most high end sun i have ever
touched:), so i do not have experience on concept like partition etc.
And talking about that excellent High Avaliable feature like
CPU/Memory corruption and the server still run,that is really something great. And i
did not know it before.And i think it is impossible to implement on that kind of low
end Dell PC servers, but for servers like V880, that is also something impossible i
think, right? We cannot compare a product whose value is 1M$ with products whose value
is 10K$:). After all, intel is still on middle-low end.
Thanks for your valueable knowledge, thanks.
Regards
zhu chao

So, what is the advantage of Sun? Redhat Advanced
server and 920 is also so much stable, and Sun T3 disk array
is also of poor performance. CPU poor, disk array not that
good, why sun?

One thing I noticed is that you were using an older Sun. The current Suns
have CPU's more than twice as fast as what you are using. It would be
interesting to see the results using a new Sun rather than an old one. I
have always thought the Dell PowerEdge series was an excellent value. But I
have always appreciated the very well thought-out design of the Sun machines
and the overall excellent package of solid hardware, very stable OS, and
excellent customer service that Sun provides.
Some capabilities of the Sun -- which might or might not exist on the Dell
(I don't know) -- are the ability to partition the machine into domains
and dynamically move resources between the domains. The Sun will run OK
with a bad memory module or bad CPU's. As long as the Sun has one working
CPU, it will run. I haven't done sys admin work for a while, but in the
past, Sun provided a utility called Symon that displayed a detailed picture
of the system boards and, if there was a problem with a component, would
show you which component had failed. Whether these features are of any
value to you depends on you. One other point in favor of the Sun is that
Sun is excellent at maintaining backward compatibility in releases of its
OS. You could, in fact, take a ten year old Sparc IPC, install Solaris on
it, and use it as a web server or file server. Almost every old (in
computer terms) Sun shop has those old lunch box (not pizza boxes) Sun's
hanging around, still perfectly usable. Something I doubt could be said
about a 10 year old Intel box.
As I have mentioned in a previous post, the SunSolve CD is an excellent
resource. One is tempted say worth its weight in gold, but it is actually
worth more than that.
As far as the preoccupation with which box can produce the best benchmark:
In my personal philosophy, either a box is fast enough to run the
application for which it is intended, or it is not. After that point those
less tangible qualities, such as those listed about, do count and should be
considered.
