the Red Hat Hardware Catalog is here:

https://hardware.redhat.com/

the PowerEdge 2650 is supported for i386:

https://hardware.redhat.com/show.cgi?id=232318

the R900 is supported under 5.1 for i386 and x86_64:

https://hardware.redhat.com/show.cgi?id=359681

this might explain some of the problems you're experiencing with 5.2
on the R900.

Is the 2650 PAE compatible?
Does the system have the latest Dell BIOS on it?

I think that you are wanting to use 64 bit Linux versus 32 bit.

Uhm no. I don't think Dell certifies CentOS to work with their OS. You
would need to contact Dell though versus CentOS.

Yes. [All caps is a sign of yelling in english... not sure what you
are aiming for.]

Does CENTOS 5.1 have similiar problem or NOT?



Thanks.


Did you try a 64 bit install?

Do you have to turn on PAE in the bios on those servers? I have HP servers
that you have to enable PAE or it doesn't work.


And CentOS isn't really "certified" with anything. Free distros don't usually
pay to be certified. But if it is listed to work on RedHat Enterprise Linux
5.2 then CentOS should also work.

Did you install the PAE kernel and are you booting the PAE kernel?


2. DELL R900 can NOT boot under CENTOS 5.2 PAE mode (inifinite boot loop)


Same as question 1.


3. DELL R900 with 128 GB RAM can only see 15 GB RAM under CENTOS 5.2 Xen mode

As others have stated, CentOS does not certify with any places that
would cost money. That is how you get it for free.

I don't think there will be any difference
