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.

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 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. Will.

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... /Peter -- ------------------------------------------------------------ Peter Kjellstr?m | National Supercomputer Centre | Sweden | http://www.nsc.liu.se -------------- next part -------------- A non-text attachment was scrubbed...
