Acacia is our disk-based storage system, powered by Dell, providing 60PB of high-speed object storage for hosting research data. This multi-tiered cluster separates different types of data to improve data availability. Acacia has been built around Ceph in-house. It is highly scalable, stable and resilient. Acacia is a significant technological change from our past storage infrastructure. With it, we have embraced object storage technologies which make for a more flexible ecosystem where research groups can more easily share and access data. We have also moved to using the open-standard S3 interface for access. If you already have an active, approved Pawsey project (Supercomputing, Nimbus or Visualisation) then you are automatically eligible for a 1TB |

Banksia is an in-place upgrade to our previous tape-based system, which consisted of two |

Spectralogic T-Finity tape libraries, each with a current storage capacity of 74 PB - mirrored for greater data protection. Data was migrated from the old Pawsey HSM to the new system, via an in-place data migration, whereby the old format tapes continue to be read by Versity software. This system was supplied by Xenon Australia and is managed by the |

ScoutAM platform from Versity operating on Intel servers. It has a 5 PB front-end DDN hybrid storage cache operating with ScoutFS to take advantage of the centre’s new 100 Gb network infrastructure. Both tape libraries have |

They each contain 32 IBM® TS1150 high performance enterprise tape library drives and 2 IBM® TS1160 next generation drives accessing over 10,000 media slots. Similar to the warm tier, we have shifted towards adopting more open standards by migrating to an |
