EPMW

Processor CoD utility billing for FC EPM0, 100 processor-minutes: 
Provides payment for temporary use of processor feature FC EPM0 
with supported AIX or Linux operating systems. Each occurrence of this 
feature will pay for 100 minutes of usage. The purchase of this feature 
occurs after the customer has 100 minutes of use on processor cores 
in the shared processor pool that are not permanently active.

EPME

One processor-day on/off billing for FC EPM0:
After an On/Off Processor Enablement feature is ordered and the 
associated enablement code is entered into the system, you must 
report your on/off usage to IBM at least monthly. This information, used 
to compute your billing data, is then provided to your sales channel. 
The sales channel will place an order for a quantity of On/Off Processor 
Core Day Billing features and bill you. One FC EPME must be ordered 
for each billable processor core day of feature FC EPM0 used by a 
supported AIX or Linux operating system.

0 to 16-core 3.8 GHz  processor card:
16-core 3.8 GHz  CUoD processor planar containing two 
8-core processors. Each processor has 2 MB of L2 cache (256 KB per 
core) and 32 MB of L3 cache (4 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.
