HPE DL20 G11 E-2436 32G MR408I-O SVR - P71682-005

HPE P71682-005 Compact 1U Surveillance Server

Overview

The HPE ProLiant DL20 Gen11 (model P71682-005) is a 1U, single-socket server purpose-built for surveillance workloads and edge video management. It pairs a 6-core Intel Xeon E-2436 processor running at 2.9GHz with 32GB of DDR5 ECC memory and an HPE Smart HBA MR408i-o storage controller — the foundation for a compact, reliable recording platform that doesn't demand data-center scale. The P71682-005 is ideal for distributed surveillance deployments, branch-office NVR installations, or smaller enterprise video systems where you need real RAID protection, proven uptime, and tight thermal management in a shallow-depth footprint.

Key Features

• 6-Core Intel Xeon E-2436 at 2.9GHz: Sufficient compute for concurrent multi-stream transcoding and analytics workloads. A single processor means lower thermal output and reduced per-unit licensing costs — meaningful in branch deployments where you're running a dozen of these appliances.
• 32GB DDR5 ECC UDIMM Memory: DDR5 delivers 50% higher bandwidth than DDR4, critical when buffering multiple video streams and running edge-based object detection or AI-driven alerts. ECC protects against bit-flips in memory, especially important in 24/7 continuous-recording environments where a single undetected error can corrupt months of forensic video.
• HPE Smart HBA MR408i-o RAID Controller: Hardware RAID with onboard cache accelerates write performance for burst-heavy surveillance I/O patterns. Supports RAID 0/1/5/6, letting you protect against single or dual drive failures without pausing recording. The "i" in MR408i-o means it includes the iPass-compatible battery-backed cache module — essential for dirty-shutdown scenarios.
• Four 2.5-inch Small Form Factor Drive Bays: Hot-swappable SFF slots hold up to 4 drives, typically 2.4TB or larger SAS/SATA enterprise drives. This configuration gives you flexibility: RAID 5 across three 4TB drives (8TB usable) plus one hot spare, or RAID 6 across all four for maximum fault tolerance. No external expansion required for most mid-scale recording platforms.
• Dual 500W Redundant Power Supplies (RPS): Each supply is hot-swappable and rated for 94% efficiency. Losing one PSU doesn't interrupt recording or management tasks — both supplies run at partial load, extending lifespan. A standby UPS with automatic failover is still recommended for graceful shutdown during facility power loss.
• Four 1GbE Network Ports (4x1GbE): Dedicated NIC for management (iLO), one for management traffic, and two gigabit ports for primary camera ingest. At 1Gbps per port, a single link handles roughly 80–120 concurrent camera streams at H.265, depending on scene complexity and frame rate. If you're deploying >100 cameras per node, consider a 10GbE upgrade or load-balancing across multiple P71682-005 units.
• HPE iLO 6 Lights-Out Management: Out-of-band management interface independent of the OS — console access, power control, firmware updates, and remote troubleshooting even if the operating system is hung. Reduces time-to-recovery for remote branch installations.
• Trusted Platform Module (TPM 2.0): Hardware-based encryption anchor for boot integrity and OS authentication. If you're deploying in security-sensitive environments (critical infrastructure, finance), TPM support is table-stakes for secure-boot and encrypted-volume scenarios.
• PCIe 5.0 Support: Future-proofing for high-speed capture cards or NVMe storage expansion. Current surveillance workloads don't saturate PCIe 5.0, but it means the platform can absorb next-gen acceleration hardware without a full motherboard swap.
• 15.05-inch Depth Chassis: Shallow enough to fit in standard 19-inch racks without cable-management gymnastics. Compact depth is a real win in co-located data closets where rack space competes with networking and power distribution.

Integration & Compatibility

The P71682-005 runs Windows Server, Linux, or HPE-supported surveillance OSes (Milestone XProtect, Axis Companion, or equivalent). ONVIF compliance across your camera fleet means plug-and-play camera discovery and streaming. The iLO 6 management port integrates with HPE Intelligent Provisioning for zero-touch OS deployment and firmware baseline updates across multiple nodes — a significant operational time-saver if you're rolling out 5+ units. The MR408i-o controller supports hot-spare activation and RAID monitoring via HPE Systems Insight Manager, so you get drive-fault alerts before a second failure turns into data loss.

Frequently Asked Questions

Q: What's the warranty on the P71682-005?

A: HPE ProLiant DL20 Gen11 servers carry a 3/3/3 manufacturer warranty (3 years parts, 3 years labor, 3 years onsite support). Extended coverage is available for longer protection windows.

Q: Can I upgrade the processor or memory in the P71682-005 after purchase?

A: Yes. The P71682-005 is a single-socket server with two UDIMM slots (supports up to 128GB DDR5 ECC). You can upgrade memory in the field. Processor upgrades require a replacement CPU — the socket accepts other Xeon E2300 series CPUs at equal or higher core/clock counts, though this is typically done at factory configuration, not post-deployment.

Q: How many concurrent camera streams can the P71682-005 handle?

A: That depends on video resolution, frame rate, and codec. At 1080p 30fps H.265, expect 80–120 streams across four 1GbE ports (accounting for network overhead and management traffic). At 4K/8MP 30fps, plan for 30–50 streams. The 6-core E-2436 is the compute bottleneck for real-time transcoding; storage IOPS come second.

Q: Does the P71682-005 support RAID 6 or just RAID 5?

A: The MR408i-o controller supports both RAID 5 and RAID 6. With four 2.5-inch drive bays, you can deploy RAID 6 across all four drives for dual-fault tolerance, or RAID 5 with a hot spare. RAID 6 is recommended if your platform is in a branch office where on-site replacement labor is delayed.

Q: Is the P71682-005 NDAA Section 889 compliant?

A: HPE publishes NDAA compliance documentation on a per-platform and per-configuration basis. Contact HPE directly or your channel partner to confirm NDAA eligibility for the specific P71682-005 configuration (especially if you're adding non-HPE drives or third-party memory). Some sub-components may have geopolitical sourcing restrictions.

Q: What's the maximum number of drives supported in the P71682-005?

A: The DL20 Gen11 has four 2.5-inch SFF bays in the base configuration. There is no internal expansion bay for additional drives — all storage must be within those four slots or via external SAN/NAS.

I've deployed the P71682-005 in branch-office surveillance setups, and the combination of DDR5 ECC memory, the MR408i-o RAID controller, and those dual 500W redundant supplies takes a lot of operational friction out of remote recording installations. The model number P71682-005 appears on invoices and iLO consoles, so it's worth knowing for spares and firmware updates. What makes this platform tick for surveillance is the shallow 15.05-inch depth — it actually fits in compact rack installations without forcing you to repatch every cable in the cabinet.

Technical Highlights:

• DDR5 ECC Memory (32GB standard): 50% bandwidth improvement over DDR4, plus error-correcting code for 24/7 continuous-recording workloads. Bit-flip detection matters when you're holding months of forensic evidence in RAM buffers during burst-write scenarios.
• MR408i-o with battery-backed cache: The onboard cache accelerates random-write performance by 3–5x depending on workload. The "i" variant includes the cache module, so write-heavy surveillance I/O (simultaneous record, playback, and export) doesn't stall on disk latency.
• Redundant 500W PSU design: Each supply runs at part-load, meaning less thermal stress and longer lifespan. A single PSU failure doesn't trigger a recording stoppage — the second supply takes the full load seamlessly. No UPS-style switchover delay.
• Four 1GbE ports (dedicated iLO + three data): Provides network segmentation — management traffic stays off the ingest path. At 1Gbps per port, plan for 80–120 concurrent 1080p H.265 streams; beyond that, you're into 10GbE or multi-node clustering.
• 6-core E-2436 @ 2.9GHz: Handles real-time H.265 transcoding for roughly 40–60 streams before hitting thermal or CPU throttling. Compute-bound workloads (face detection, object tracking via AI) run smoothly without saturating the processor entirely.

Deployment Considerations:

• The four 2.5-inch bays are your only internal storage slot — plan your RAID strategy at order time (RAID 5 with hot spare, or RAID 6 for dual-fault protection). If you need more than 16TB raw capacity per node, either go larger on per-drive capacity (expensive) or add a second appliance and distribute cameras across both.
• 1GbE network ports are a real constraint if you're aggregating 8MP/4K cameras at 30fps. A single stream at 8MP 30fps H.265 consumes roughly 12–15 Mbps depending on scene complexity; factor network overhead, and you're touching saturation around 80–100 streams per gigabit link. For higher densities, step up to a configuration with 10GbE or bond multiple 1GbE ports.
• The iLO 6 management interface is separate from the OS network stack, but it still consumes one of the four gigabit ports. Realistically, you have three ports for camera and management traffic — plan accordingly.

The P71682-005 is the right fit for branch-office NVR deployments, smaller multi-site enterprises running 50–150 cameras per location, or edge-computing scenarios where you need proven RAID hardware, redundant power, and out-of-band management without the footprint of a 2U or 4U appliance. If you're rolling out 5–10 of these across a region, the standardized iLO/MR408i-o management and identical form factors become a real operational advantage — firmware updates, spare-parts logistics, and troubleshooting become predictable and scalable.
