PST installation

Resource requirements

When deploying this release for the first time, please note that PST has some additional requirements on the servers running their components. Consult the following resources for more information:

• Resource Requirements resource requirements in the PST documentation

• JIRA ticket STS-1251

Workarounds

Due to some known issues, the following workarounds should be applied when deploying this release for PST to work.

Configure PST receiver MAC address

As reported in SPRTS-277, the current version of the LOW-CBF beamformer firmware hard-codes the following destination MAC address in its output packets:

94:6d:ae:92:a3:c5

The network adapter used by PST therefore needs to match this MAC address for these packets to arrive.

When using a Kubernetes NetworkAttachmentDefinition to assign a network adapter to PST, the MAC address can be configured through the annotation set on the PST Core component:

values.yaml

ska-pst:
  core:
    podAnnotations:
      k8s.v1.cni.cncf.io/networks: '[{"name":"net-att-def-name", "namespace": "kube-system", "mac":"94:6d:ae:92:a3:c5"}]'

Configure PST receiver port

As reported in SKB-626, the current version of LOW-CBF hard-codes the destination port in its output packets. The PST deployment therefore needs to be configured to use the correct port for its receiver:

values.yaml

ska-pst:
  core:
    applications:
      recv:
        ports:
          datastream:
            port: 9510
            targetPort: 9510

General Notes

Jupyter Notebooks

Accompanying this release of ska-low-csp is a set of Jupyter Notebooks that demonstrate several pieces of functionality. These notebooks can be found at https://gitlab.com/ska-telescope/ska-low-csp/-/tree/main/notebooks/aa05.

Warnings and errors related to PSS

As with the previous release, the logs of some of the LOW-CSP sub-systems may contain errors and/or warnings related to PSS. These can be safely ignored, as PSS is currently not included in ska-low-csp.
