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.
Will.

For the event to get more RAM some time in future, I would go with x86_64. What do these hosts run? I expect them to be servers and not workstations with desktop users. I then vote for x86_64, runs pretty well for me with CentOS 4. Especially encryption tasks profit from the 64bit, like HTTPS or other TLS connections.

I'm not 100% sure of their workload, there's some Java/Tomcat/Jakarta, Postgres and Apache. I imagine it'll be app/db on the larger box and the 2 smaller systems being app/webservers. I need to verify this. Given the Java part of the equation their memory requirements are bound to go up. :)
For all the Java cruft required I was planning on sticking with packaged installs from Jpackage so I should probably check what they have available.

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...
