Most data center advisory firms are built by consultants who have studied infrastructure. Sentinel Asset Intelligence was built by someone who has lived it.
Darryl Barnes brings 12 years of hands-on data center engineering and regional asset management experience to every Sentinel engagement. Before founding Sentinel Asset Intelligence, Darryl spent over a decade in the trenches of enterprise data center operations — troubleshooting servers, leading infrastructure build-outs, managing regional asset operations, overseeing decommissioning projects, and negotiating directly with the world's largest hardware vendors.
That experience isn't theoretical. It's the kind of knowledge that only comes from physically building, maintaining, and retiring infrastructure at scale — understanding not just what the data says, but what it means and what to do about it.
Before his career in data center engineering, Darryl served in the United States Army — where he developed the discipline, attention to detail, and commitment to mission that defines how Sentinel Asset Intelligence operates today. We don't miss things. We don't cut corners. And we don't stop until the job is done right.
That military precision carries directly into how we serve clients. Every assessment is thorough. Every report is documented. Every finding is backed by evidence. Every recommendation is made with your best interest as the only priority.
Mid-market companies are caught in a difficult position. They have data centers complex enough to require serious expertise — but not large enough to justify a full-time team of engineers and asset managers. The result is infrastructure that's undermanned, undermonitored, and quietly draining budget in ways that never get caught until something breaks.
Sentinel Asset Intelligence exists to close that gap. We bring the expertise of a seasoned engineer and asset manager directly to your environment — on demand, at a fraction of the cost of building an internal team.
After 12 years on the inside of enterprise data center operations, Darryl knows exactly how vendor relationships work, where the hidden costs live, and what good asset management actually looks like versus what companies think it looks like.
We know how vendors manipulate refresh cycles to drive unnecessary upgrades. We know which monitoring alerts matter and which ones are noise. We know what a CFO needs to see to approve a budget and how to build the business case to get it approved. That insider knowledge is what we bring to every engagement — and what no amount of studying can replicate.

Every Sentinel client receives four professional reports, a live asset monitoring portal, monthly advisory reviews, and on-demand access to their advisor. We don't hand you a presentation and disappear. We stay in the work with you.
No referral fees. No preferred partners. No conflicts of interest. Every recommendation we make is driven by one thing — what's best for your environment and your budget. We are your advocate. Full stop.
Attention to detail isn't a buzzword here — it's how we were trained. Every assessment is thorough, every report is documented, every recommendation is delivered on time. We watch what others miss.
When you work with Sentinel Asset Intelligence you get direct access to your advisor — not a ticketing system, not a call center, not a junior analyst. You get Darryl Barnes, with 12 years of experience and a personal commitment to making sure your infrastructure never becomes a liability.
Every client is treated as if their environment is the only one we're managing. Because the integrity of your data center is not something we take lightly — and neither should you.
