Learn the fabricthat keeps AI clusters alive.
InfiniBand. RoCEv2. RDMA. Congestion control. Scale-out fabric design. ProDeploy teaches AI and HPC networking through interactive chapters, stateful labs, and a simulator built for network engineers.
The gap
There is no Packet Tracer for HPC networking.
Network engineers who can troubleshoot BGP, reason about ECMP, and design VxLAN fabrics still walk into AI data centers and find an unfamiliar world. The knowledge is fragmented across vendor docs, conference talks, and incident writeups.
ProDeploy turns that scattered knowledge into a structured, open platform. Chapters explain the hardware and protocols. Labs let you test commands against live state. Anyone can contribute a correction, a new lab, or a sharper explanation.

Chapter 17
Storage Network Packet Path
A packet-level walkthrough of a checkpoint write from GPU HBM to storage appliance: NVMe-oF capsules, DMA paths, storage-fabric behavior, frame anatomy, and diagnostics.
Chapter 18
OOB and Management Network
The out-of-band management fabric: BMC architecture, IPMI and Redfish internals, OOB topology, switch management isolation, UFM communication paths, BlueField-3 management architecture, and hardening guidance.
Chapter 19
IP Addressing and Planning
A complete addressing reference for DGX BasePOD and SuperPOD deployments: address families, RFC 1918 partitioning, loopback design, P2P links, /32 server routes, management-plane planning, VXLAN VNI allocation, and scaling pitfalls.
Chapter 20
Ultra Ethernet Consortium (UEC)
Why RoCEv2 has friction at scale, and how UEC addresses it: UET packet format, SACK-based reliability without lossless fabric, 1-RTT congestion feedback, native multipath spraying, switch requirements, and honest deployment readiness as of March 2026.
Chapter 21
Congestion Control Deep Dive
A rigorous, algorithm-level treatment of every congestion control scheme used in production AI fabrics — DCQCN, Swift, HPCC, TIMELY, and UEC CC — with practical guidance on parameter tuning and algorithm selection.
Chapter 22
Segment Routing for AI Fabrics
A practitioner's guide to deploying SRv6, SR-TE, EVPN+SRv6, and IS-IS Flex-Algo in production AI data centre fabrics.
Chapter 23
AI Networking Security
The complete security layer for AI fabrics: RDMA threat model, RoCEv2 RKEY protection, Spectrum-X GBP microsegmentation, InfiniBand PKey isolation, BlueField-3 as a security enforcement point, and UFM Cyber-AI anomaly detection.
Chapter 24
Spectrum-X Architecture and the AI Factory Platform
NVIDIA Spectrum-X: Spectrum-4 ASIC, BlueField-3 SuperNIC, DOCA, NetQ, and the vertically integrated Ethernet platform behind AI factory fabrics.
Chapter 25
RoCE Configuration and Operations on Spectrum-X
Configure RoCEv2 end to end on Spectrum-X: prerequisites, NVUE Day-0 workflow, QoS architecture, ECN/PFC tuning, and production verification.
Chapter 26
Adaptive Routing and Per-Packet Spraying on Spectrum-X
Why flow-based ECMP fails AI collectives, how Spectrum-4 Adaptive Routing reacts to queue depth, and how BF3 reorder buffers make per-packet spraying viable on Spectrum-X.
Chapter 27
BGP-EVPN Multi-Tenancy on Spectrum-X
How Spectrum-X enforces tenant isolation using BGP-EVPN, VXLAN, and GBP microsegmentation - from VNI planning to route-target configuration and operational troubleshooting.
How it works
Three systems. One learning loop.
Structured chapters
Connect hardware, transport behavior, congestion control, and operator workflow in one guided read.
Stateful CLI labs
Commands read live lab state, so the simulator reacts to the exact fault you are tracing.
Open source
Every chapter, lab and visualisation lives in the repo. Read the source, fork it, or send a correction.
Who this is for
Built by a network engineer, for network engineers.
CCNP / CCIE engineers
You can read BGP tables and design VxLAN fabrics. You have not spent time inside InfiniBand or RoCE yet. ProDeploy is the transition-[color,background-color,border-color,box-shadow,opacity] duration-200 path.
HPC cluster administrators
You manage the servers, but the fabric still feels opaque. ProDeploy closes the gap between compute operations and network operations.
Cloud and platform architects
You are designing GPU infrastructure and need to understand what lossless fabrics demand at the protocol and operational level.
Network engineers growing into AI infrastructure
AI fabrics are a fast-moving specialisation. ProDeploy gives you a structured path before the first production incident lands on your desk.
