LOW-CSP Helm Chart

The deployment of LOW-CSP is done using the ska-low-csp Helm chart. This chart integrates the components of the LOW-CSP LMC, LOW-CBF, PST and PSS sub-systems. These components are included as sub-charts of the ska-low-csp chart.

Note

The PSS sub-system is currently not yet included in LOW-CSP.

Sub-system Components

The LOW-CSP Helm chart contains the following sub-system charts:

Sub-system	Chart	Description
LOW-CSP LMC	ska-csp-lmc-low	This chart contains the LowCspController and LowCspSubarray TANGO devices, which are used for Monitoring & Control of the LOW-CSP system. Documentation: SKA Low CSP.LMC.
LOW-CBF	ska-low-cbf	This chart contains the LowCbfController, LowCbfSubarray and LowCbfAllocator TANGO devices, which are used for Monitoring & Control of the LOW-CBF sub-system. Documentation: Low.CBF Tango Devices for Monitoring and Control.
LOW-CBF	ska-low-cbf-proc	This chart contains the LowCbfProcessor TANGO device, which controls the FPGAs used by LOW-CBF to perform their correlation and beamforming functionality. Documentation: ska-low-cbf-proc.
LOW-CBF	ska-low-cbf-conn	This chart contains the LowCbfConnector TANGO device, which controls the P4 switches used to route science data from SPS through the LOW-CSP into SDP. Documentation: ska-low-cbf-conn.
PST	ska-pst	This chart contains all PST sub-system components. Documentation: SKA-PST.

Configuration

The following Helm values are used to configure the ska-low-csp Helm chart. The default values can be found in charts/ska-low-csp/values.yaml.

Parameter	Description
ska-csp-lmc-low	Configuration of the ska-csp-lmc-low Helm chart. For an overview of possible values, refer to the LOW-CSP.LMC Helm values.
ska-low-cbf	Configuration of the ska-low-cbf Helm chart. For an overview of possible values, refer to the LOW-CBF Helm values.
ska-low-cbf-conn	Configuration of the ska-low-cbf-conn Helm chart. For an overview of possible values, refer to the LOW-CBF Connector Helm values.
ska-low-cbf-conn.enabled	Disables the ska-low-cbf-conn Helm chart, to support deploying to environments without the required LOW-CBF hardware.
ska-low-cbf-proc	Configuration of the ska-low-cbf-proc Helm chart. For an overview of possible values, refer to the LOW-CBF Processor Helm values.
ska-low-cbf-proc.enabled	Disables the ska-low-cbf-proc Helm chart, to support deploying to environments without the required LOW-CBF hardware.
ska-pst	Configuration of the ska-csp-lmc-low Helm chart. Refer to SKA PST Helm Chart Parameters.
ska-pst.enabled	Disables the ska-pst Helm chart, for environments where PST is not explicitly desired.

For an example of how the ska-low-csp Helm chart is deployed to Digital Signal PSI, refer to helmfile.d/values/ska-low-csp.yaml.
