DDN's ExaScaler Lustre appliance was chosen for use on Taiga currently running Exa 5 based on Lustre 2.12, with an upgrade to Exa 6 (Lustre 2.14) planned for early Spring 2022 .  Lustre is a highly scaleable and performant HPC file system with a growing number of features that help support bare metal workloads but also VMs and Containers.  Newer Lustre features such as sub-directory mount, PFL, and DNE2 DNE3 are being leveraged on Taiga in addition to tools and features provided by DDN's ExaScaler platform such as snapshots and the Stratagem policy engine.
