(Optional) Configure interrupt affinity settings

This feature enables you to assign the interrupts that support affinity settings to the specified CPUs. After that, the interrupt requests will be processed by the specified CPUs. As a best practice to prevent the interrupts from affecting the tasks on the isolated CPUs, do not assign the interrupts to isolated CPUs.

Procedure

  1. On the top navigation bar, click Hosts.

  1. Select the target host, and then click the Advanced tab.

  1. Click the Interrupt Affinity tab.
