Capacity On Demand; Capacity Upgrade On Demand (Cuod); On/Off Capacity On Demand (On/Off Cod) - IBM Power 780 Technical Overview And Introduction

2.4 Capacity on Demand

Several types of capacity on Demand (CoD) offerings are optionally available on the
Power 770 and 780 servers to help meet changing resource requirements in an on-demand
environment, by using resources that are installed on the system but that are not activated.

2.4.1 Capacity Upgrade on Demand (CUoD)

With the CUoD offering, you can purchase additional permanent processor or memory
capacity and dynamically activate them when needed, without requiring you to restart your
server or interrupt your business.

2.4.2 On/Off Capacity on Demand (On/Off CoD)

With the On/Off CoD offering, you can temporarily activate and deactivate processor cores
and memory units to help meet the demands of business peaks such as seasonal activity,
period-end, or special promotions. When you order an On/Off CoD feature, you receive an
enablement code that allows a system operator to make requests for additional processor
and memory capacity in increments of one processor day or 1 GB memory day. The system
monitors the amount and duration of the activations. Both prepaid and post-pay options are
available.
Charges are based on usage reporting that is collected monthly. Processors and memory
may be activated and turned off an unlimited number of times, when additional processing
resources are needed.
This offering provides a system administrator an interface at the HMC to manage the
activation and deactivation of resources. A monitor that resides on the server records the
usage activity. This usage data must be sent to IBM on a monthly basis. A bill is then
generated based on the total amount of processor and memory resources utilized, in
increments of Processor and Memory (1 GB) Days.
New to both Power 770 model MMD and Power 780 model MHD are 90-day temporary
On/Off CoD processor and memory enablement features. These features enable a system to
temporarily activate all inactive processor and memory CoD resources for a maximum of 90
days before ordering another temporary on/off enablement feature code is required. Also
announced for Power 770 model MMD are high density memory DIMMs using 4 GB
technology. This technology provides memory DIMMs for 64 GB, 128 GB, and 256 GB DDR3
memory feature codes. IBM continues to offer the 32 GB, 2 GB memory feature.
Before using temporary capacity on your server, you must enable your server. To enable, an
enablement feature (MES only) must be ordered and the required contracts must be in place.
If a Power 770 or Power 780 server uses the IBM i operating system in addition to any other
supported operating system on the same server, the client must inform IBM which operating
system caused the temporary On/Off CoD processor usage so that the correct feature can be
used for billing.
The features that are used to order enablement codes and support billing charges on the
Power 770 and 780 are described in 1.4, "System features" on page 6 and 1.4.7, "Memory
features" on page 18.
