Sun will very willingly support all certified solutions (including EMC, netApp or Hitachi for storage) as well as provide some support with uncertified hardware for us... no issues...
You work in a Fortune 5, they will do anything you tell them. I've been there before, and that is a very nice position to hold.
But not when you work for a 50 engineer semiconductor startup. Sun really pissed us off regularly, so we stuck with Fujistu.
Yep - but how is that a benefit if your stuff works? NVidia is fabless i.e. and you surely don't want to tell me they aren't good at what they do... Having your own fab or not has very little influence...
I was just saying that anyone who only wants to go to Sun because they are behind SPARC might consider Fujitsu, who actually fabs the chips. I've walked into many shops who have had issues with Sun's support and they never knew about Fujitsu as an option. That's all.
Sbus ???? Now you're talking US-I/II again - and that is absolutely no match for an opteron box...
Sorry, I meant NUMA/UPA -- my bad.
Based on what? The Implementation of Solaris for AMD dates back to SE b68 or 69... that's mid 2004... Compare that to an OS that already ran on the software emulator before silicon was even out there...
Solaris was _also_ running on the x86-64 emulator too. ;->
AMD and Sun were in negotiations before the first Opteron came out.
Solaris 10 on AMD64 is definitely less stable that Centos 4 on the same v40z... Running the same apps we had 0 crashes with Linux vs. 2 explained and patched, 1 explained still unpatched and 1 unexplained crash on Solaris10...
I meant the design: "given its experience on partial mesh interconnected systems"
I thought by putting that in the _same_statement_ you'd see what I meant by "mature." Sorry, I assumed wrong. ;->
Why would you need to run on sparc to produce a stable OS for an opteron box?
Re-read my full statement ...
'Solaris is probably the most "mature" OS for Opteron 200/800 right now, given its experience on partial mesh interconnected systems.'

Actually that's before I started working there... Support is the one thing sun is good at... Honestly, they hardware is pretty bad quality wise - especially their volume server line... Fujitsu surely has much better control over their QA process...

Yep - I agree - HAL made a great chip ... out of order execution on a architecture that has register windows is impressive engineering...

Yep - but only in 32bit mode...

Really? didn't know that... Thought it wasn't until much later... 2003 or so...

Fair enough - still not stable in my experience and the sun support guys I talked to pretty much openly admitted that many others share the same experience as us... The first update was a great improvement though...

Hey, CentOS build wizards!!! Would you mind messing something up... not anything really bad... but just a little nitpickin' thing... like maybe whacked out command prompt.. or some goofy graphic somewhere, or .. you know.. something not really systems critcal... so we have something to talk about on this list that is CentOS related? :)
Again, I guess this sums up the state of affairs... great work... fast timing.... any bugs don't really belong here, but on Redhat Bugzilla! Awesome job!!!!
And I guess I'll let us now return to our regularly scheduled discussion of SPARC and blah <delete> blah <delete> blah <delete>. But I was hoping the Hot swap CPU thread would head over the the Proliant line to let me know how well those are working out.... IF anyone has ever had to do it.
Best, John Hinton
