IBM 6C1 - Manual (Page 30)

22 pSeries 610 Models 6C1 and 6E1 Technical Overview and Introduction
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.
