In other news, I note that the Event Horizon Telescope (EHT) used the well known (to beowulf list members) “station wagon full of disk drives” approach to high bandwidth, high latency data comm. This technique does have significant history in the VLBI field (station wagon full of digital or analog tapes). The effective data rate from the telescope in Hawaii to MIT was 112 Gbps (700TB of data in 50,400 seconds).
Same trick the pulsar astronomers at Swinburne used to do with Apple Xserve RAID boxes taking empty drives from Melbourne to Parkes and returning with full drives with data. These days they have connectivity out to the dish thankfully!
This also had an application in HEP in Australia when it was cheaper to fly someone to Japan to the KEK collider to recover data on tape than it was to ship it over the 'net back to Australian researchers.
