SPBM compliance check just got faster in vSphere 6.7 U1!

vSphere 6.7 U1 includes several enhancements in Storage Policy-Based Management (SPBM) to significantly reduce CPU use and generate a much faster response time for compliance checking operations.

SPBM is a framework that allows vSphere users to translate their workload’s storage requirements into rules called storage policies. Users can apply storage policies to virtual machines (VMs) and virtual machine disks (VMDKs) using the vSphere Client or through the VMware Storage Policy API’s rich set of managed objects and methods. One such managed object is PbmComplianceManager. One of its methods, PbmCheckCompliance, helps users determine whether or not the storage policy attached to their VM is being honored.

PbmCheckCompliance is automatically invoked soon after provisioning operations such as creating, cloning, and relocating a VM. It is also automatically triggered in the background once every 8 hours to help keep the compliance records up-to-date.
