Integrating with Temporary Instant Capacity
(TiCAP)/ Pay per use (PPU)
This section discusses the use of WLM with Temporary Instant Capacity
(v6 or later) or Pay per use (v4, v7, or later). (Instant Capacity was
formerly known as iCOD.) In particular, with WLM managing the use of
these CPU resources, you can ensure your workloads use only the
amount of resources needed for them to meet their SLOs.
Temporary Instant Capacity activates capacity in a temporary
“calling-card fashion” such as in 20-day or 30-day increments (where a
day equals 24 hours for one core). With this option, you can activate and
deactivate temporary capacity cores. You purchase a TiCAP codeword to
obtain rights to use these cores for a preset amount of days. This
codeword is applied to a system so you can turn on and off any number of
Instant Capacity cores on your system as long as your prepaid amount of
temporary capacity days has not expired. WLM integrates with
Temporary Instant Capacity v6 or later and can be configured to activate
or deactivate temporary capacity cores as needed. (To activate a core, you
need a minimum balance of 30 minutes of temporary capacity per core.
Codewords must be applied in the order in which they were obtained.)
Similarly, HP offers a Pay per use (PPU) feature for customers interested
in leasing CPU capacity from HP Finance. The Pay per use (PPU) feature
provides the capacity to support peak anticipated demand, but with
payment for the HP server based on monitored usage of that capacity.
WLM integrates with PPU v4, v7, or later. On systems with PPU v4,
capacity can be increased or decreased by whole cores—as needed, with
billing determined by the number of active cores. Beginning with PPU
v5, all cores on a PPU system are active and billing is based on your
percentage usage of those cores. Starting with PPU v7, which includes v5
capabilities, billing can also be based on the number of active cores on
the system, with WLM activating only those cores that are needed.
If you have WLM on either a Temporary Instant Capacity system (using
v6 or later) or a PPU system (using v4, v7, or later), you can configure
WLM to minimize the costs of using these resources by optimizing the
amount of time the resources are used to meet the needs of your
workloads.
