Hello.
I have to jump in and give my credos to Sun, as well. When I first began
working at Computervision almost 13 years ago, it was at a time when they
began their port to Sun (from their own proprietary hardware). Throughout
my time at CV, they ported to many flavors of Unix (SunOS, Solaris, HPUX,
Irix, Dec Ultrix, Dec Alpha, AIX) then eventually NT, all the IT personel
praised Sun (always dissing Ultrix and AIX). As I ventured from being a
developer to a release engineer to a Unix Administrator, I, too, understood
their high praises for Sun. I'm now at a company within Fidelity that has
mainly RS6000's (AIX - major yuk) and Sun's. Here, too, Sun is the most
stable platform. We sailed through Y2K without a glitch. Nearly three
months ago I replaced our Clearcase server's hardware configuration from an
IBM RS6000 F40 with a Hardware RAID5 disk array for two Sun Ultra II's with
two 200Mhz CPU's each, 2GB RAM each, dual [FCAL] looped with two Sun
Storedge A5200 disk arrays managed by Veritas VxVM + VxFS. We support a
development environment of roughly 20 developers and 15 QA staff. The
performance suits us just fine. I have had a minor concern about
scalability with the Ultra II's because they are each maxed out for memory,
but with the vob data we have (and a limitation/hump we just go over with
one vob's Clearcase DO reference count reaching the 2GB limit) we should be
fine for quite some time.
Our release engineers have given me some numbers and the users have
already seen on average a 17% improvement in build times.
And I have to admit, I have an easier time fixing Sun hardware than I do
IBM hardware. IBM and AIX is any Unix' Administrator's nightmare as far as
I'm concerned.
Well, enough praises for Sun for one day. We don't want them getting too
cocky on us, do we? Ha ha!

Subject: AW: [cciug] Advice on choosing a UNIX server for Clearcase
Start of rant
Beg to disagree. I have 15 years experience of Unix, most flavours from
Unix system III edition 7 onwards. Solaris is the most stable O/S that I
have come across, it's is the most supportable and easiest to use. And,
let's face it, there ain't a software package worth having that isn't ported
to Solaris. I also recall a conversation with Oracle who said that the most
stable Unix solution for Intel platforms was Solaris.
I don't work for Sun and I don't think that the Sun (no pun intended) shines
out of their backsides. Like every other supplier and software author they
have their problems. But (as Hughie Green would say) and I mean this most
sincerely folks, you would be a fool to not consider Sun.
End of rant
All of the above is IMHO of course.
