We have been running AMD Opteron x86_64 processors in priority 1 production systems under heavy load with no issues due to the opterons. Issues you may encounter would involve proprietary drivers / software which just don't support x86_64 well. We really haven't seen any problems with hardware that has support built into the stock kernel. The Opterons are our preferred platform for Linux now because of the price / performance. We've been very pleased with the HP DL385/585 platforms. The new Sun Galaxy servers (4100/4200) look quite nice, but we've only just finished qualifying them, so we don't have them in any P1 environments yet. As for Itaniums . . . I haven't looked at them in about 8 months or so but they suffered from several problems. #1 They are expensive, #2 they use an insane amount of power, #3 they generate an insane amount of heat, #4 they were very unreliable in our environments. The vendor rep swore up and down we had just gotten unlucky so . . . with only 5 boxes I can't make a call on a whole processor line. After that experience though it would take some serious convincing to get me to try Itanium again. Russell On 5/15/06, Miner, Jonathan W (CSC) (US SSA) < jonathan.w.miner@xxxxxxxxxxxxxx> wrote:

Issues? Please provide some references, or examples of what AMD/RHEL problems you're referring to.
