Most AI clusters deliver well under what they were built to deliver. Your product story should start there.

Product strategy and go-to-market advisory for AI and data center infrastructure vendors — networking, storage, DPUs, and the systems that keep GPUs busy.

The GPU Utilization Gap Two bars: rated cluster capacity, and an illustrative lower bar for sustained useful compute. The difference is idle capital. Rated capacity 100% Sustained useful compute Illustrative the gap synchronization stragglers · data stalls contention · scheduling
The GPU Utilization Gap: the distance between a cluster's rated compute and the useful compute distributed training actually sustains. Illustrative; actual utilization varies significantly by model, scale, and metric (MFU, GPU busy time, training throughput). On a cluster costing tens of millions of dollars, that distance is idle capital.

A systems view of AI infrastructure

Faster GPUs and wider fabrics are necessary but no longer sufficient. Past a few hundred GPUs, the limit stops being any single component and becomes how well compute, communication, data movement, and scheduling are coordinated. That coordination layer — not FLOPS or link speed — decides how much of the hardware is realized.

This is the framework I use with clients, developed across a series of articles published in 2026 and refined in vendor engagements.

Hardware provides potential. Orchestration determines what is realized.

  1. The AI Synchronization Tax Idle GPU time accrued while collectives such as AllReduce complete. Every step advances at the pace of the slowest participant, and the cost grows with cluster size.
    Microbursts, incast, tail latency, congestion control behavior under collective load.
  2. The GPU Utilization Gap Synchronization is one contributor. Stragglers, data-pipeline stalls, network contention, and scheduling fragmentation add the rest — and they compound rather than add.
  3. The orchestration layer A distinct layer between rated capacity and achieved throughput: communication patterns, workload placement, data pipelines, and network behavior under load.
  4. What good orchestration looks like Minimize synchronization overhead. Overlap compute and communication. Reduce variability. Keep data flowing. Design for how the system behaves at scale, not at the pilot.
  5. Where systems break down at scale Inefficiencies that are noise at 64 GPUs become deterministic limiters at 4,000. Diagnosing them means understanding interactions, not components.

Where I help

Each area of the AI stack contributes to the utilization gap, and each has a product story to tell about closing it. My work is turning that story into positioning, competitive framing, and content that engineers and buyers both trust.

AI networking and lossless fabrics

Scale-out and scale-up fabrics, Ultra Ethernet and RoCEv2 positioning, congestion control, packet spraying, in-network collectives, and the practical differences between 400G and 800G deployments.

Gap it addresses: the synchronization tax, contention, tail latency.

DPUs, SmartNICs, and offload

Where communication, storage, and security offload actually move the needle in inference and training clusters, and how to position a DPU against hyperscaler in-house silicon and merchant NICs.

Gap it addresses: CPU-bound data loading, host-side jitter, collective efficiency.

Storage and data platforms for AI

GPU-direct paths, NVMe-oF, parallel and object storage, KV-cache tiers for inference, and the disaggregated-versus-array decision for training data pipelines.

Gap it addresses: data-pipeline stalls, storage and network contention.

AI infrastructure economics

Cost per useful token, utilization as the real ROI lever, power and rack-density constraints, and the training-to-inference shift in capital allocation.

Gap it addresses: the case for efficiency over adding more GPUs.

Engagements

Fixed scope, named deliverables. Most work is with founders, CMOs, and product leaders at networking, storage, and silicon companies.

Work

Twenty-five years of product marketing and product management in networking and storage, the last fifteen as an independent advisor. Recent engagements include AI cluster networking, 400G infrastructure, RDMA, AI storage, SmartNIC/DPU positioning, and AI infrastructure benchmarking. Selected clients:

Positioning a lossless fabric for AI clusters against InfiniBand and RoCE

For a high-performance networking vendor, led product positioning and go-to-market messaging across its portfolio, including a proprietary high-performance fabric architecture and its 400G platform, as the company moved from its HPC base into AI training and inference clusters. Sharpened differentiation versus InfiniBand and RoCE around the properties that govern GPU utilization at scale — lossless, congestion-free operation and predictable collective performance — and advised on product branding and launch marketing.

Turning AI networking silicon into a market story

For a semiconductor startup building networking silicon for AI and data center infrastructure, provided strategic, product, and technical marketing that translated complex capabilities — including a virtual prototyping platform and an RDMA implementation for AI scale-out fabrics — into customer-facing positioning and collateral. Produced solution briefs, white papers, and thought-leadership content on data movement in AI clusters for the company's go-to-market program.

Building visibility and mindshare in defense markets

For a networking hardware vendor, led strategic marketing and thought leadership to strengthen visibility and mindshare in priority markets, particularly defense-related application segments. Published targeted technical blogs, developed customer success stories, and ran strategic public relations programs designed to reinforce differentiation, build credibility, and raise awareness within key customer and partner communities.

Perspectives

Sustained GPU utilization: a systems view of AI infrastructure

The six-part series on why AI clusters underdeliver at scale, from the synchronization tax to the orchestration layer, collected as one framework with diagrams.

Read the series
  1. Beyond GPUs and bandwidth: improving AI system efficiency

    Why system-level efficiency, not GPU count or link speed, sets the ceiling on AI cluster performance.

  2. Where AI infrastructure breaks down at scale

    Synchronization, variability, data movement, contention, and scheduling stop being independent problems and start compounding.

  3. What does good AI orchestration look like?

    Five principles that consistently separate efficient clusters from merely large ones.

  4. AI infrastructure is a systems orchestration problem, not a hardware problem

    Why adding GPUs and bandwidth can widen the gap between rated and achieved performance.

  5. The GPU Utilization Gap in AI clusters

    Why theoretical GPU performance rarely translates into training throughput, and what the shortfall costs.

  6. The hidden bottleneck in AI clusters: synchronization

    Introducing the AI Synchronization Tax and why faster fabrics alone do not eliminate it.

Earlier bylines at TechTarget cover storage architectures for AI, edge AI deployment, and SmartNIC market segments.

How I work

I start from the engineering reality of the product and work outward to the buyer, rather than the reverse. Most engagements begin with a short scoping call, a fixed-price proposal, and a defined deliverable list. Rates on request.

Who I work with

Founders and CEOs at early- and growth-stage infrastructure companies; CMOs and product leaders at established vendors launching a new generation; standards bodies and consortia that need technical positioning for a broad audience.
