잠김 Mixed processor cores in same failover cluster

    Currently I have a 3 node (2 active and 1 passive) Windows 2008 x64 Enterprise Edition Failover cluster. The processors on the machine are all AMD Opteron 8380 (quad core processors). We are considering upgrading our nodes from quad cores to the AMD Opteron 8439 hex core processor architecture. However, we want to make sure that there isn't any reason this wouldn't work properly.

    Previous to Windows 2008 Server the rules for having a supported cluster configuration were quite rigorous. Now if the cluster validation tool runs to completion and the cluster passes all the tests, Microsoft will support it.

    Unfortunately, we're not in a position to purchase the server just to try it out. Has anyone out there done anything similar? Would someone from Microsoft please weigh in if this should work or not? Does anyone know if quad and hex core processors from the same manufacturer will play nicely in the same failover cluster?

    I'm in the process of talking with the manufacturer to see if they have any information about this as well.

    Thanks in advance for your help.

      Hi,

       

      General speaking, we recommend that you use the identical hardware on all the nodes, however, sometimes we can’t get the identical hardware because of the suspend production of the special part of the computer.

       

      So, in Windows Server 2008 R2, you can Migrate to a physical computer with a different processor version, for more information, you can refer to:

       

      Configure Memory and Processors

      By the way, the following post discussed the similar issue, you can refer to:

       

      Hyper-V R2 cluster nodes, similar hardware

      Best Regards,

        We have done testing between various AMD CPUs, and it works even without processor compatibility mode enabled. We even added a dual Opteron 2435 server to a cluster which is quad 8354 processors, and it works flawlessly (once the AMD processor hotfix has been installed!).
