Guys,
I'll be building a couple of DL360 G4p & DL380 G4 boxes soon and I've not dealt extensively (i.e. at all) with any PC stuff that hasn't been i386. I know the DL line pretty well but it was all G2/3.
So, question is, do I stick CentOS i386 or x86_64 on them? 2 boxes x 2GB RAM and 1 x 4GB, all SMP.
I'd say, let your applications decide for you. Application compatibility (especially 3rd party) will be better on i386. But if you don't have any such issues x86_64 is the way to go.
The 2nd thing to consider is memory addressing, this will be better on x86_64 (especially on your 4 GiB box). i386 will split your 2 or 4 GiB into low mem and high mem and that will be harder for applications to use than the flat model provided by x86_64.
And in the end, if at all, consider possible performance differences...
