The document discusses the use of Ceph for storing data from the MeerKAT radio telescope in South Africa. It describes the SARAO Ceph clusters used for storage, including SeeKAT-C1 and SeeKAT-C3, which store over 18 petabytes of data. It also outlines SARAO's data access and movement processes using Ceph RADOS gateways and S3. The document shares lessons learned about hardware failures and cluster balancing and discusses future plans such as upgrading clusters and building storage for an expanded MeerKAT telescope.
