  • 1.  hyperthreading is shown as disabled

    Hi,

    I have a HP Proliant DL 580 G5 server and I have installed ESXi on it.

    I have verified Intel VT is enabled in BIOS, but when I look at the client from vsphere, I see hyperthreading as inactive and EVC mode is disabled.

    Please see the doc.

    Can someone please advise what could be wrong ? Thanks

    the CPU in question does not support hyperthreading

    EVC needs to be enabled from within the vSphere client and isn't necessary unless you have multiple ESX(i) hosts with different processor families.

    HI,

    I am about to add another DL 580G5 server to the cluster. How can I enable HyperThreading from vsphere client or from virtual center ?

    as troy indicated the CPU in question does not support hyperthreading and if it did you would have to enable it in the BIOS
