A discussion on the MeerKAT Radio Telescope, currently nearing completion in the Karoo desert region of South Africa. This talk covers a quick introduction to radio astronomy data processing and the scale challenges inherent therein. The solutions to the challenges posed will be discussed, including coverage of our MESOS based execution framework and the role of the various data storage regimes in our processing and analysis pipelines. The final third will highlight our multiple uses of CEPH, including our self-build hardware, 20PB science archive.
