An important feature of the new licensing model is the concept of pooling the vRAM capacity entitlements for all processor licenses. The vRAM entitlements of vSphere CPU licenses are pooled – that is, aggregated – across all CPU licenses managed by a VMware vCenter instance (or multiple linked VMware vCenter instances) to form a total available vRAM capacity (pooled vRAM capacity). If workloads on one server are not using their full vRAM entitlement, the excess capacity can be used by other virtual machines within the VMware vCenter instance. At any given point in time, the vRAM capacity consumed by all powered-on virtual machines within a pool must be equal or lower than the pooled vRAM capacity
