HPE ProLiant Gen10 vs Gen11: A Generation Apart
Hewlett Packard Enterprise’s ProLiant server line has been the backbone of enterprise data centers for decades. The Gen10 series — anchored by the DL360 Gen10 and DL380 Gen10 — has been one of HPE’s most successful generations, shipping millions of units worldwide since 2017. The Gen11 series, launched in 2022, brings a fundamental architecture shift with DDR5, PCIe Gen5, and iLO 6.
If you are evaluating HPE servers for your next deployment, this comprehensive comparison will help you understand exactly what you gain with Gen11 — and why Gen10 remains a compelling value proposition in 2026.

DDR4 vs DDR5: The Memory Generation Gap
The most fundamental difference between Gen10 and Gen11 is the memory architecture. Gen10 uses DDR4, while Gen11 moves to DDR5. This has far-reaching implications:
DDR5 Advantages
- 50% higher bandwidth: DDR5-4800 delivers 38.4 GB/s per channel vs 25.6 GB/s for DDR4-3200
- Higher density: DDR5 modules are available in larger capacities, enabling more RAM per slot
- Better power efficiency: DDR5 operates at 1.1V vs DDR4’s 1.2V
- On-die ECC: Additional error correction at the chip level (separate from system-level ECC)
DDR4 Advantages (Today)
- Lower cost per GB: Despite the current DDR4 shortage, DDR4 modules are still cheaper per gigabyte than DDR5
- Mature ecosystem: Widely available from multiple manufacturers, well-understood compatibility
- Proven reliability: Years of deployment data across millions of servers
For memory-intensive workloads where bandwidth is critical (HPC, AI inference, large databases), DDR5 provides a measurable performance uplift. For general-purpose workloads, the real-world difference is less dramatic.
iLO 5 vs iLO 6: Management Platform Comparison
HPE’s Integrated Lights-Out (iLO) is the remote management backbone of every ProLiant server. Gen11 introduces iLO 6 with several improvements:
| Feature | iLO 5 (Gen10) | iLO 6 (Gen11) |
|---|---|---|
| Web Interface | HTML5 | Modernized HTML5 |
| Remote Console | HTML5 + .NET IRC | HTML5 (improved) |
| REST API | Redfish | Redfish (expanded) |
| Security | Silicon Root of Trust | Silicon Root of Trust + CNSA 2.0 ready |
| Firmware Update | iLO Repository | iLO Repository + Always-On Management |
| Telemetry | Basic | Enhanced (streaming telemetry) |
iLO 6 is an evolution, not a revolution. If you are comfortable with iLO 5, the transition is seamless. The key additions are enhanced security posture (CNSA 2.0 compliance for government/defense workloads) and improved telemetry for proactive monitoring.
PCIe Gen3/4 vs Gen5: I/O Bandwidth Comparison
PCIe generation has a direct impact on storage and network performance:
| PCIe Generation | Per-Lane Bandwidth | x16 Slot Bandwidth | Available On |
|---|---|---|---|
| PCIe 3.0 | ~1 GB/s | ~16 GB/s | Gen10 |
| PCIe 4.0 | ~2 GB/s | ~32 GB/s | Gen10 Plus |
| PCIe 5.0 | ~4 GB/s | ~64 GB/s | Gen11 |
Gen11’s PCIe 5.0 support is particularly important for:
- Next-gen NVMe SSDs: PCIe 5.0 NVMe drives can deliver 12,000+ MB/s sequential reads
- 200GbE networking: High-speed network adapters benefit from doubled per-lane bandwidth
- GPU accelerators: AI and HPC workloads that require maximum data throughput to accelerator cards
- CXL (Compute Express Link): Gen11 introduces CXL support for memory expansion and pooling
DL360 Comparison: Gen10 vs Gen11
The DL360 is HPE’s workhorse 1U rack server. Here is how the generations compare:
- DL360 Gen10: Up to 2x Xeon Scalable 2nd Gen, 24 DIMM slots, PCIe 3.0, iLO 5. Ideal for virtualization, web, and application hosting at an aggressive price point.
- DL360 Gen11: Up to 2x Xeon Scalable 4th/5th Gen, 16 DIMM slots (DDR5), PCIe 5.0, iLO 6. Best for performance-demanding 1U deployments.
Like the Dell R640/R650 comparison, the Gen10 DL360 has more DIMM slots (24 vs 16) while Gen11 compensates with faster DDR5 and wider I/O.
DL380 Comparison: Gen10 vs Gen11
The DL380 is the world’s best-selling server, period. The 2U form factor provides more expansion room:
- DL380 Gen10: Up to 2x Xeon Scalable, 24 DIMM slots (3TB max), up to 30x 2.5″ bays, 8 PCIe slots. The versatile enterprise workhorse.
- DL380 Gen11: Up to 2x Xeon Scalable 4th/5th Gen, 32 DIMM slots (4TB max DDR5), PCIe 5.0, up to 40x 2.5″ bays. The next-gen platform with more of everything.
The Gen11 DL380 actually increases DIMM slots from 24 to 32, unlike the 1U models. Combined with DDR5 density, this makes it the most memory-expandable mainstream HPE server ever.
Price Comparison: Refurbished Gen10 vs Gen11
| Server | Refurbished Gen10 | Gen11 (New/Refurb) | Savings |
|---|---|---|---|
| DL360 (2P, 128GB, 2x SSD) | ~$1,500 | ~$3,500 | ~57% |
| DL380 (2P, 256GB, 8x SSD) | ~$2,500 | ~$5,500 | ~55% |
| DL560 (4P, 512GB) | ~$4,000 | ~$9,000 | ~56% |
Refurbished Gen10 systems offer 50% to 60% savings compared to equivalent Gen11 configurations. For many workloads, Gen10 remains more than sufficient.
When to Choose Gen10
- Budget-driven deployments: Gen10 offers enterprise-grade performance at a fraction of Gen11 pricing

- DR and secondary sites: Perfect for disaster recovery and non-production environments
- Lab and development: Enterprise hardware for testing at refurbished prices
When to Choose Gen11
- Greenfield deployments: Building new infrastructure benefits from the latest platform
- Performance-critical workloads: Databases, HPC, AI inference, and analytics that benefit from DDR5 bandwidth and PCIe 5.0
- Long lifecycle planning: Gen11 will be supported by HPE well into the 2030s
- Compliance requirements: CNSA 2.0, FIPS, and government security standards
- CXL workloads: Future-proofing for memory pooling and composable infrastructure

Frequently Asked Questions
Can I use DDR4 memory in an HPE ProLiant Gen11 server?
No. Gen11 ProLiant servers use DDR5 memory exclusively. DDR4 and DDR5 use different physical connectors and are not interchangeable. If you have existing DDR4 inventory, Gen10 or Gen10 Plus servers can utilize it.
Is HPE iLO 5 still receiving firmware updates?
Yes, as of early 2026. HPE continues to release security patches and bug fixes for iLO 5. However, new features and enhancements are primarily focused on iLO 6. iLO 5 will eventually enter maintenance-only mode as Gen10 approaches end of support.
Which HPE ProLiant Gen10 servers support PCIe 4.0?
The Gen10 Plus variants (DL360 Gen10 Plus, DL380 Gen10 Plus) with 3rd Gen Intel Xeon Scalable (Ice Lake) processors support PCIe 4.0. Original Gen10 models with 1st or 2nd Gen Xeon Scalable are limited to PCIe 3.0.
What is CXL and why does it matter for Gen11?
CXL (Compute Express Link) is a high-speed interconnect built on PCIe 5.0 that enables memory expansion and pooling beyond what is physically installed in a server. Gen11 servers with CXL support can access shared memory pools, enabling more flexible and cost-effective memory scaling for memory-intensive workloads.
Does ICD provide support for HPE ProLiant Gen10 servers after HPE warranty expires?
Yes. ICD offers third-party maintenance (TPM) and SPaaS (Server Parts as a Service) for HPE ProLiant servers that have exited HPE warranty coverage. This includes guaranteed parts availability, replacement SLAs, and technical support. Contact us for a custom support plan.
