Enhanced Platform Awareness in Kubernetes

1. RAVI SHARMA

2. ENHANCED PLATFORM AWARENESS
"Enhanced Platform Awareness" (EPA) represents a methodology to get workload placement
understand underlying platform to deliver improved and deterministic application
performance, and IO throughput.
It enables fine-grained matching of workload requirements to platform capabilities, prior to
launching a VM or Container.
From CNTT – VIM requirement

3. MAIN EPA FEATURES
EPA features include
• Multiple interfaces
• Device Plugins (incl. SR-IOV)
• Huge Pages
• NUMA topology
• CPU pinning and isolation
• Node Feature Discovery

4. NODE FEATURE DISCOVERY
• Node Feature Discovery (NFD) is a Kubernetes* add-on that detects and advertises
hardware and software capabilities of a platform that can, in turn, be used to
facilitate intelligent scheduling of a workload.
• Node Feature Discovery is part of the Enhanced Platform Awareness (EPA) suite
which represents a methodology and a set of changes in Kubernetes targeting
intelligent configuration and capacity consumption of platform capabilities.
• Node Feature Discovery detects these features and advertises them through a
Kubernetes concept called node labels which, in turn, can be used to control
workload placement in a Kubernetes cluster. NFD runs as a separate container on
each individual node of the cluster, discovers capabilities of the node, and finally,
publishes these as node labels using the Kubernetes API.
• Allocatable resources that require accounting, initialization and other special
handling (such as Intel® QuickAssist Technology, GPUs, and FPGAs) are presented as
Kubernetes Extended Resources and handled by device plugins.

5. NODE FEATURE DISCOVERY
NFD currently detects the following features:
• CPUID
• SR-IOV networking
• Intel® RDT: Intel® Resource Director Technology
• Intel® Turbo Boost Technology
• IOMMU: An input/output memory management unit
• SSD storage
• NUMA topology
• Linux* kernel
• PCI
