New in this release::
|
|
* No reference design updates in this release
|
|
|
|
Description::
|
|
Use the Performance profile to configure clusters with high power mode, low power mode, or mixed mode.
|
|
The choice of power mode depends on the characteristics of the workloads running on the cluster, particularly how sensitive they are to latency.
|
|
Configure the maximum latency for a low-latency pod by using the per-pod power management C-states feature.
|
|
|
|
Limits and requirements::
|
|
* Power configuration relies on appropriate BIOS configuration, for example, enabling C-states and P-states.
|
|
Configuration varies between hardware vendors.
|
|
|
|
Engineering considerations::
|
|
* Latency: To ensure that latency-sensitive workloads meet requirements, you require a high-power or a per-pod power management configuration.
|
|
Per-pod power management is only available for Guaranteed QoS pods with dedicated pinned CPUs.
