IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction
Figure 1-3 shows the top view of the Power 770 and Power 780 system with four SCMs
installed. The four SCMs and the system memory reside on a single processor
card feature.

Several types of capacity on demand (CoD) processor options are available on the Power 770
and Power 780 servers to help meet changing resource requirements in an on-demand
environment by using resources installed on the system but not activated. CoD allows you to
purchase additional permanent processor or memory capacity and dynamically activate it
when needed.
More detailed information about CoD is in 2.4, “Capacity on Demand” on page 58.

EPM0 0 to 12-core 4.22 GHz processor card:
12-core 4.22 GHz CUoD processor planar contains four
3-core processors. Each processor has 756 KB of L2 cache (256 KB
per core) and 40 MB of L3 cache (10 MB per core). There are 16 DDR3
DIMM slots on the processor planar (8 DIMM slots per processor),
which can be used as Capacity on Demand (CoD) memory without
activating the processors. The voltage regulators are included in this
feature code. AIX
