I have a cust
pounding a Sun E450 I believe they
said it was with a
large RAID with fiber channels.
They pound this
thing at 2,037 I/O per seconds and
end up having about
3,868 I/O per data block wait.
This is averaged
over 3-5 days, 24 hr/day, so there
are times it's way
over that. While sometimes slow,
performance is
acceptable most of the time.
They are
contemplating moving it to Linux and a
very high end Dell
system, perhaps 4-8 CPU, etc.
I've always heard
Sun was pretty much the best
on heavy I/O and if
it were not for the
fiber channels,
they would probably have
been hurting big
time some time ago.
They are only in
R&D right now, but has anyone
done a move of this
nature?
The database is
Siebel with many mods and
sub systems,
average tuned, about 76gb. It
is about 139
million records. They are around
200 users or
so.
