Artificial intelligence isn’t just changing the game—it’s rewriting the rules. From life-saving medical research to real-time logistics optimization, today’s breakthroughs hinge on raw compute muscle. But with every leap forward in AI capability comes a harder truth: our infrastructure is choking on the demand.

 

Traditional servers weren’t built to handle the energy-hungry, heat-intensive nature of modern AI workloads. Data centers are overheating, power bills are ballooning, and deployment cycles drag into months. Add in the security risks of operating at global scale, and most enterprise stacks simply aren’t built for what’s next.

 

That’s where the HPE ProLiant XD685 enters the conversation. It’s not just a server—it’s a liquid cooled AI server that shatters the ceiling on compute density, energy efficiency, and time-to-deployment. Purpose-built for enterprise-scale LLMs, multimodal AI, and high-stakes data science, this system reimagines what high-performance computing should look like in the age of AI.

 

With up to eight GPUs per chassis, direct liquid cooling that cuts energy waste by 30%, and security baked into the silicon, the ProLiant XD685 isn’t just more powerful. It’s smarter. Faster. Greener. And more secure. For CIOs and infrastructure leads, this isn’t just another upgrade—it’s a strategic pivot.

 

 

1. Unmatched Performance for Cutting-Edge AI Workloads

 

Eight Accelerators. One Chassis. No Compromises.

 

The HPE ProLiant XD685 doesn’t dabble in AI. It was engineered for it. At its core: a modular chassis with support for up to eight of the most advanced accelerators available today—NVIDIA H200, Blackwell, or AMD Instinct MI300X. This is not your average server. It’s the kind of muscle that turns a rack into a supercomputing node.

 

Whether you’re training trillion-parameter language models or running inference on multi-modal pipelines, the XD685 delivers the kind of raw throughput that collapses project timelines from months to weeks. NVIDIA’s 4th-gen Tensor Cores and AMD’s CDNA 3 architecture aren’t just fast—they’re ruthlessly efficient, ensuring every watt drives meaningful computation.

 

This isn’t theoretical performance. It’s the difference between deploying in Q3 and shipping in Q1.

 

The CPU Bottleneck? Eliminated.

 

Every powerhouse needs a balance of strength and speed. That’s why the XD685 is armed with 5th Gen AMD EPYC™ processors, purpose-built to keep data pipelines saturated. With 24 DDR5 6400 RDIMMs and 12 memory channels per socket, this system ensures your GPUs are never waiting on data. The architecture delivers memory bandwidth that turns latency into a non-issue.

 

Think of it as pairing a racecar with a precision pit crew. The EPYC CPUs fuel the GPUs relentlessly, maintaining peak utilization for longer cycles—and ultimately, delivering faster model convergence and higher ROI per node.

 

Choose Your Thermal Arsenal: Air or Liquid

 

AI workloads don’t all run the same, and neither should your server configurations. The XD685 offers both 6U air-cooled and 5U liquid-cooled designs—each tailored to real-world deployment strategies.

 

Running smaller clusters or easing into AI adoption? Air-cooled gives you plug-and-play familiarity with serious horsepower. Going full-throttle into large-scale AI? The liquid cooled AI server config lets you stack eight GPU nodes per rack, maximizing density while trimming energy overhead.

 

Either way, you’re not locked into yesterday’s hardware. The XD685 is built for modularity—future-proofed to support next-gen GPUs, thermal systems, and evolving AI demands.

 

2. Liquid Cooling—Powering Sustainability and Cost Savings

 

Why Air Cooling’s Days Are Numbered

 

When you’re dealing with GPUs pushing past 1000 watts, air cooling just can’t keep up. Fans struggle. Heat builds. Performance throttles. And your power bills skyrocket. The HPE ProLiant XD685 flips that script with direct liquid cooling (DLC)—a technology engineered not just for performance, but for sustainability at scale.

 

By circulating coolant directly to the system’s thermal hotspots—think GPU modules and memory banks—DLC cuts energy consumption by up to 30%. That’s not just cooling. That’s cost control. Fewer fans. Less airflow. Lower ambient temperatures. And most critically: no compromise on performance.

 

DLC also unlocks dense compute configurations in a tight 5U chassis, allowing eight fully loaded nodes per rack. That means fewer racks, less floor space, and lower total infrastructure costs. The result? Faster time-to-insight without the bloated carbon footprint.

 

 

A Legacy You Can Build On

 

HPE didn’t discover liquid cooling last quarter. They’ve been perfecting it for decades, powering some of the world’s most demanding workloads—from supercomputers to hyperscale data centers. That legacy is deeply embedded in the XD685 design.

 

This isn’t experimental. This is enterprise-grade cooling with battle-tested reliability. It runs quieter, cooler, and longer, even when operating under 24/7 load in extreme environments. And it pays dividends far beyond the electricity bill: longer hardware life, fewer thermal failures, and tighter alignment with ESG mandates.

 

With the XD685, HPE gives you an infrastructure advantage that’s not just greener—it’s smarter.

 

3. Modular Design for Scalable AI Clusters

 

A Chassis That Grows With You

 

The HPE ProLiant XD685 isn’t just about power—it’s about architectural agility. Its modular chassis design gives you the flexibility to adapt on the fly. Whether you’re deploying a handful of nodes or scaling up a continent-wide AI cluster, the XD685 moves with your roadmap.

 

Choose from a 5U liquid-cooled or 6U air-cooled variant based on your thermal requirements and rack strategy. More importantly, the system is hot-swappable and field-upgradable, allowing you to upgrade GPUs, swap CPUs, or evolve your cooling solution without re-racking or rewriting infrastructure.

 

That’s how you build for the AI unknown—by refusing to lock into static hardware assumptions. And with hybrid cooling support baked in, you can run mixed thermal environments side-by-side, optimizing for both performance and practicality.

 

High-Density Compute Without the Trade-Offs

 

Every rack unit costs money. Every square foot of data center floor adds to TCO. The XD685 gives you 8 accelerators per chassis without compromising thermal efficiency or manageability—especially in its liquid cooled AI server configuration.

 

This high-density architecture makes it a natural fit for enterprises deploying large-scale transformer models, AI inference grids, or scientific simulations at volume. You get more performance per rack, more results per watt, and more throughput per dollar.

 

Need to scale? Just add nodes. No extra real estate required.

 

4. Built-in Security—Protecting Your AI Investments

 

Trust Begins at the Silicon

 

AI is valuable. That makes it a target. From IP theft to firmware tampering, the threats are real—and rising. That’s why the HPE ProLiant XD685 doesn’t treat security as an add-on. It starts where it matters most: at the hardware level.

 

With HPE iLO 6, every XD685 server includes a silicon root of trust, a cryptographic fingerprint that validates firmware integrity before a single line of code executes. If something’s off—whether it’s unauthorized firmware or compromised components—the server won’t boot. It’s security at the atomic level.

 

This embedded resilience ensures that from power-on to workload execution, your infrastructure is hardened against today’s most advanced supply chain and firmware attacks.

 

Zero Trust, Fully Embedded

 

The XD685 operates with a Zero-Trust Architecture at its core. Every user, every firmware package, every peripheral—it all gets authenticated. There are no assumptions, no shortcuts. Unauthorized access attempts are blocked before they reach critical systems. Suspicious behavior is logged and flagged in real time.

 

In an AI-driven world, where proprietary models and datasets are the crown jewels, this level of defense isn’t optional—it’s non-negotiable.

 

Real-Time Defense Without the Overhead

 

While traditional servers react after breaches, the XD685 is built to anticipate and prevent them. Features like secure boot, continuous firmware validation, and encrypted memory channels ensure that even active workloads remain shielded against intrusion.

In effect, the XD685 serves as both a compute engine and a sentinel—running your AI workloads at full speed while constantly watching the gates.

 

5. Simplified Management for Rapid Deployment

 

AI at Scale Without the Operational Headaches

 

Deploying AI infrastructure used to be an exercise in chaos—manual configurations, long setup times, and never-ending troubleshooting. The HPE ProLiant XD685 changes that calculus with a management layer built for velocity and simplicity.

 

At the center of this transformation is HPE Performance Cluster Manager (HPCM). Think of it as the command center for your AI operations—automating software deployment, cluster provisioning, and telemetry monitoring across every node. It syncs your hardware, firmware, drivers, and workloads like a conductor leading a complex AI orchestra.

 

Need to stress test GPUs before launch? HPCM handles it. Want real-time metrics on thermal load and power draw? It’s built in. By automating routine tasks and surfacing actionable insights, HPCM lets your engineering teams focus on building models, not babysitting servers.

 

Factory-Built Speed, On-Site Simplicity

 

Time is a luxury in AI development. That’s why HPE Factory Express Services pre-configure, test, and integrate every ProLiant XD685 server before it even reaches your facility.

 

Whether you need a hybrid cooling configuration, custom firmware settings, or accelerator-specific drivers, the servers arrive ready to power up—no on-site wiring marathons or last-minute surprises. What used to take weeks of setup is compressed into hours of activation.

 

This is infrastructure as a service—but on your terms, in your data center, fully tailored to your stack.
