This Gauge32 indicates how many levels deep in the UCS Manager organizational hierarchy (org/sub-org tree) this memory configuration policy is defined, which matters because a policy defined deeper in the org tree overrides one with the same name inherited from a parent org. An admin troubleshooting why a service profile picked up unexpected DIMM-blacklisting behavior would check this to see whether a lower-level, more specific policy silently won out over the org-root default. A policyLevel of 0 means the policy sits at org-root, while a value of 2 would mean it's defined two sub-organizations deep.
