2.3.1 The Cluster-Level Object Manager (CLOM)
The CLOM exists as a userspace daemon on each ESXi host in the vSAN cluster and is responsible for:
• Orchestrating objects.
• Placement of objects during create operations.
• Ensuring that component placement satisfies the defined storage policy.
• Scheduling rebuilds should a component need to be replaced.
o With a placement operation, it verifies that policies are satisfied.
o If an object is reconfigured with a new storage policy, the CLOM handles the placement of any new components required.
