Hi,
Has anyone successfully installed Centos4 on the newer AMD powered Sun gear? I really want to hear if there are gotchas or lost/decreased functionality. a

V20z here ( and atleast 2 other CentOS Devel's ) and it works out of the box, excellent bit of kit. I have it running on x86_64, but did run it on i386 as well for a few days. Didnt have a problem either way.
Btw, large portions of CentOS4/i386 and x86_64 are built on Sun kit these days.....

Hi,
Thanks that gives me a semi-good feeling. But the V20z has been discontinued. Did you get serial console access via the LOM card?

I use the console over IP, redirecting serial link into the management interface. I am quite sure it would work over serial native as well. But you need the platform drivers ( details in Johnny's post ) in case you intend to remote manage power and OS state - either over a ssh link into the interface or over the web management interface.
also, try not top posting - it really screws readability on the thread.

Right ... they now only sell them as the base for appliances (like firewalls).
But they are basically the same as V40z's .. the best I can tell.
We have IP accessible SP (at least that is how I set this on up):

Rick,
Sun donated 3 machines to the CentOS Project that are V20z's
See this story: http://www.centos.org/modules/news/article.php?storyid=128
These machines have working flawlessly with CentOS-4.3 (and 3.7) installed.
Both the i386 and x86_64 arches have been installed ... as has VMWare Server Beta with VM's for both i386 and x86_64.
I did build and install the latest platform drivers from Sun (nps- V2.4.0.2-0.i386.rpm) ... and I did build and install the broadcom drivers (bcm5700-smp-7.3.5_2.6.9_34.EL-rhel4_2.i686.rpm) provided by Sun as well. (that was i386 arch ... you can build the x86_64 versions too).
I have been super pleased with these machines.
Thanks, Johnny Hughes CentOS-4 Lead Developer

We have a few of them - works fine. If you're running a larger DB or something, you get a huge performance boost out of proper numa settings in your grub.conf ... for us, it showed between 10 and 25%

Now, now, you can't tease like that. What do you mean by "proper numa settings", how do they correlate to BIOS settings, and how did you determine all that?

Sorry - I was in a hurry.
Depending on your version you either have numa enabled by default or you just add a "numa=on" to your grub kernel parameters. If enabled or enabled depends on the version - i.e. if you have dual core cpus 4.1 disables numa by default and you need to enable it by hand.
Can't remember anything in the bios about it though... check with numactl --hardware if you have numa support enabled.
The rest mostly depends on the applications you're running. Numactl is a much underused utility. If you run just one process that takes up the majority of memory/cpu then numactl will be for you. If each cpu has enough memory for your processes, --localalloc can work very well - if you have a long running process with many threads, --interleave can show better performance.
Bascially, once you have numa support enabled (if it is not already), try run your apps with numactl and different options and see which ones perform best :-)
Peter.
