You can specify CPU configuration to improve resource management. However, if you do not customize CPU configuration, the ESXi host uses defaults that work well in most situations.

You can specify CPU configuration in the following ways:

  • Use the attributes and special features available through the vSphere Client. The vSphere Client allows you to connect to the ESXi host or a vCenter Server system.
  • Use advanced settings under certain circumstances.
  • Use the vSphere SDK for scripted CPU allocation.
  • Use hyperthreading.
