In HP BIOS (DL380G7 system), it is possible to disable core. Options : activate one core, half the cores or all the core. This is applicable to each processor in the system. So if I have a single quad core processor and use "half the core" only two CPU will be availble to ESX.
I need that so I can control the nb of real active core that has a direct effect on software cost (bind to this nb of available core in the machine).
I am running vSphere 4.0 and 4.1. Is there anybody have used this "disable core" feature with vSPhere? Is that fully supported by VMWare? What is the impact (cons) other than reducing performance capacity?
Thank you.
