Storage and Networking: Rook on Multus
Talkat KubeCon + CloudNativeCon North America 2021 · on Wednesday, 2021-10-13· at 16:30· Concourse Hall 152 + Online·
summary
Demo cluster runs Rook‑Ceph using Rook-Ceph on Multus and macvlan with Whereabouts IPAM, creating network-attachment-definitions for separate public and cluster networks. Measurements show ~20–35% gains: ~35% higher random‑write IOPS and ~22% higher throughput when OSDs use a dedicated replication network. Configuration uses multus annotations, host interfaces (eno1/eno2), and Rook network selectors; setup is reproducible and available since Rook 1.7, and the demo confirms the performance boost in a bare‑metal Kubernetes environment.
