Note 2: The format of the Content strings is specific for each different orchestration templating technology used (Helm, Teraform, etc.). Currently only a format for use with Helm charts is suggested: "helmchartname:[<subchartname>.]0..N[<parentparamname>.]0..N[<paramname>]”. Whether the optional parts of the format are present depends on how the parameter is declared in the helm chart. An example is: ChartNamechartName:subChartName1.subChartName2.subChartName3.ParentParaName1ParentParamName1.ParentParaName2ParentParamName2.ParentParaName3ParentParamName3.paramName.
Note 3: A direct attached (passthrough) network interface, such as an sriov interface, attaches to a network via only one of the two switch planes in the infrastructure.
When using a direct attached network interface one therefore commonly in a pod uses a mated pair of sriov network attachments, where each interface attaches same network but via different switchplane.
The application uses the mated pair of network interfaces as a single logical “swith-path-redundant” network interface – and this is represented by a single ExtCpd.
Also there is a case where a third “bond” attachment interface is used in the pod, bonding the two direct interfaces so that the application do not need to handle the redundancy issues – application just uses the bond interface.
In this case all three attachments are together making up a logical “switch-path-redundant” network interface represented by a single ExtCpd.
