NetApp Trident on SUSE Virtualization: just the YAMLs
A copy-paste version of my Harvester knowledge base article on NetApp Trident: every manifest and command for NFS, iSCSI and NVMe/TCP backends, with as little prose as possible.

Longhorn v2 on SPDK: TCP catches up, RDMA still wins on latency (part 1)
Two snapshots of Longhorn’s SPDK-based v2 engine on the same three Ampere nodes: 1.12 with my RDMA patches, then 1.14 development builds with a newer SPDK. NVMe/TCP got about 7× lower write latency and now fills a 25 GbE link. RDMA still halves write latency.

What a summer of work on SUSE Virtualization’s LVM CSI driver taught me: why a thin pool’s chunk size can cost you 98% of your IOPS, what changed upstream, the new VM storage settings in 1.9.1, and what encryption at rest costs.
