We received our SUN X4600 with 8 dual opteron processors and 64GB RAM and I turned it on yesterday. I had no problems installing Scientific Linux 4.3 but I had a little difficulty with openafs because the kernel-module-openafs was not built for the ELlargesmp kernel on the 4.3 iso images. This kernel was the default installation kernel. However I found the required RPMS on Scientific.Linux..../40rolling and downloaded them and they seem to do the job. So now all I have to do is install the applications that will be used and put some users on the machine.
