Dynamic Processor Deallocation The capability of Dynamic Processor Deallocation is only active in systems with more than two processors, because device drivers and kernel extensions, which are common to multi-processor and uniprocessor systems, would change their mode to uniprocessor mode with unpredictable results. Therefore, it could not be used in the Models 6C1 and 6E1.

Capacity Upgrade on Demand (CUoD) Capacity Upgrade on Demand (CUoD) is a new feature that allows you to have inactive processors installed on your system, which can be made active quickly and as easily as your business needs require.
