Infiniband Storage at Scale

Deliver predictable high throughput and low tail latency with RDMA storage you can operate with confidence.

Storage teams face two constant pressures, throughput that holds under real load and tail latency that does not spike when jobs fan out. Generic TCP guidance rarely gets you there.

This book gives you a practical, end to end path for InfiniBand and RDMA in enterprise SAN and parallel file systems, from slot maps and routing to QoS, congestion control, and day two operations.

• translate hdr and ndr labels into delivered capacity and pcie limits
• set up opensm with stable discovery, lids, routes, and partitions
• choose routing modes, fat tree and clos, with selection guidance
• design service levels, sl to vl maps, and vl arbitration that protect metadata
• apply congestion control with safe parameters and a rollback plan
• tune linux rdma hosts, irq affinity, numa placement, perftest baselines
• deploy san over rdma, srp, iser, and nvme over fabrics with working configs
• ship nfs over rdma, svcrdma and xprtrdma, optional kerberos, health checks
• run spectrum scale over verbs, set rdma knobs, and verify gpudirect storage
• scale lustre over infiniband, ko2iblnd credits, routers, and test matrices
• use ibdiagnet and ufm snapshots, fio and ior pipelines, counter based triage
• isolate tenants with p key policy, manage keys, credential rotation, and logging
• execute change windows for qos and cc with sequencing that avoids tails
• adopt reference designs with bom, capacity worksheet, and growth steps
• migrate from tcp based nas and san to rdma with risk containment
• run day two backups of sm state and detect config drift automatically
• pass a plus gate checklists with proof points and exit criteria per workload

The manuscript includes reference designs for small, medium, and large estates, a capacity worksheet, operational runbooks, and production gate checklists so teams can move from plan to proof without guesswork.

This is a code heavy guide with working bash and python snippets that you can paste into build books and automation to get repeatable results.
