In this section we describe the flow of signals from the MWA receivers to the correlator and then into long term storage at the MWA Archive at the Pawsey Supercomputing Centre, illustrated in the diagram below.
Media Converter
48 fibre-optic cables from the existing 16 MWA receivers in the field enter the control building. This proposal calls for them to be directly connected to existing “EDT” cards located in 8 servers (+ 2 hot spares) selected and re-tasked from the existing pool of 16 VCS servers that are currently used in the legacy correlator. These will become media converter “Medconv Servers”, responsible for taking the bespoke protocol from the receivers and converting them to the same data format we directly receive from NI FlexRIO and SNAP based receivers (both of which are potential future MWA receiver candidates).
