NeSI's Flexible HPC-A programmable infrastructure for science
summary
NeSI builds FlexiHPC: a multi-tenant bare metal platform combining OpenStack, Magnum/Kubernetes and cloud-native stacks to offer on-demand and dedicated hardware tenancies. Initial footprint is ~1000 vCPUs, 30 TB NVMe, 0.5 PB object store with some GPUs and a 100 G fabric. Networking uses BGP/VPNs into the national R&E network, OVS hardware offloads on Mellanox ConnectX‑6, and identity via Keycloak/FreeIPA. A Gen3 taonga genomic repo runs in production on Magnum; several OpenStack/Magnum patches are upstream or proposed.
