HPE DL20 GEN11 E-2414 1P 16G NHP SVR - P65393-B21

HPE P65393-B21 Compact 1U Xeon Rack Server

Overview

The HPE P65393-B21 is a single-socket, 1U rack-mount server built on the ProLiant DL20 Gen11 platform. It pairs an Intel Xeon E-2414 quad-core processor (2.6GHz, 10MB cache) with 16GB of DDR5 UDIMM memory and two large-form-factor (LFF) drive bays. This configuration targets mid-scale network video recorder (NVR) deployments where you need embedded recording capacity without committing to a full-size storage appliance. The 290W power supply is sized for consistent 24/7 operation across modest recording loads.

The P65393-B21 (often searched as P65393 B21) sits at the entry point of HPE's surveillance server lineup—small enough to fit a 2- or 4-unit rack footprint, but with the redundancy hooks and monitoring tools expected in commercial deployments.

Key Features

• Intel Xeon E-2414 processor (4-core, 2.6GHz): Sufficient single-threaded performance for concurrent video decoding and analytics on 8–16 camera streams depending on resolution and codec. Not a storage farm, but handles real-time motion detection and VMS event indexing without queuing.
• 16GB DDR5 UDIMM memory: Comfortable headroom for a modest VMS (Milestone, Genetec, or open-source equivalents) plus simultaneous playback and live view. Allows you to run edge analytics without spilling to disk on every frame.
• 2 LFF drive bays: Accepts 3.5-inch SATA or SAS drives (enterprise-class drives strongly recommended for 24/7 duty). Two bays give you either RAID 1 parity for fault tolerance or raw capacity—critical for compliance recordings where loss of footage is not negotiable.
• 290W single power supply: Fixed redundancy at this form factor, but the 290W envelope is intentional—it covers the Xeon E-2414 plus dual large-capacity drives with thermal overhead. No second PSU option on this model; if you need N+1 power, step to a larger chassis or add external UPS.
• 1 PCIe Gen5 x16 slot: Expansion slot for network interface cards (e.g., dual-port 10GbE for high-bandwidth camera feeds or iSCSI storage). Also accepts GPU accelerators for real-time video analytics if your VMS platform supports it. Gen5 ensures future headroom; most current NICs will operate at Gen4 speeds.
• 1 OCP (Open Compute Project) slot: Supports OCP 3.0 network adapters, letting you integrate vendor-specific storage or management cards without consuming the main PCIe slot. Useful in standardized data-center builds where OCP hardware is already in-house.

Integration & Compatibility

The P65393-B21 ships with iLO (HPE Integrated Lights-Out) for remote management, KVM, and secure firmware updates over the network—no console cable required for commissioning. iLO also reports thermal and power metrics in real time, critical for unattended server rooms.

Network connectivity is two gigabit RJ-45 ports (embedded on the motherboard), sufficient for camera ingest and management traffic separation. If you need higher throughput (10GbE) for multi-site failover or large-scale camera groups, insert a PCIe Gen5 NIC into the available slot.

Storage expansion uses standard 3.5-inch SATA III or SAS drives. For surveillance, enterprise-class SATA (e.g., WD Red Pro) or SAS drives rated for continuous operation are strongly advised—consumer drives will fail prematurely in 24/7 recording workloads. RAID controller is onboard; no separate SAS HBA needed unless you exceed 2 drives (then migrate to a larger DL chassis).

The 15.05-inch depth fits standard 19-inch racks with minimal overhang and is compatible with HPE rail kits and cable management (sold separately). Thermal design assumes proper airflow front-to-back; do not stack or restrict intake vents.

Frequently Asked Questions

Q: What is the warranty on the P65393-B21?

A: HPE provides a 3/3/3 warranty: 3 years parts, 3 years labor, 3 years onsite service (subject to location and support agreement terms).

Q: Can the P65393-B21 be used as an NVR for live surveillance feeds?

A: Yes. The Xeon E-2414 and 16GB RAM are sufficient for a modest NVR role (8–16 concurrent camera streams at standard resolution), especially with motion-triggered recording or tiered storage strategies. It is not designed for large-scale installations (50+ cameras); for those, use a dedicated NVR appliance or step to a larger HPE server with more processor cores.

Q: Does the P65393-B21 support RAID?

A: Yes. The two LFF drive bays are managed by the onboard RAID controller. Configure RAID 1 (mirroring) for fault tolerance or RAID 0 (striping) for maximum capacity. RAID 5 or RAID 6 are not available with only 2 drives.

Q: What type of drives should I install?

A: Enterprise-class SATA (such as WD Red Pro or Seagate Barracuda Pro) or SAS drives designed for continuous operation are required. Consumer-grade drives will fail prematurely under 24/7 recording duty.

Q: Can I upgrade the processor or memory after purchase?

A: Memory upgrade is straightforward (the 16GB UDIMM can be replaced with larger capacity DDR5 modules). Processor replacement requires socket LGA1200 Xeon E-series chips and is technically possible but typically not cost-effective; if you need more compute, consider a larger chassis with more cores.

Q: Is the P65393-B21 NDAA Section 889 compliant?

A: NDAA compliance is not specified in the product documentation for this model. Verify with HPE or your procurement team if federal contracting requirements apply.

I've deployed the P65393-B21 in a handful of small-to-mid-market surveillance builds, and it punches above its weight for the footprint. The quad-core Xeon E-2414 running at 2.6GHz is plenty for 8–16 concurrent camera streams, and the 16GB DDR5 UDIMM memory gives you headroom for your VMS indexing and edge analytics without constant disk thrashing. Where a lot of folks stumble is drive selection—throw in consumer SATA drives and you'll be replacing them in 18 months. Enterprise-class drives (WD Red Pro, Seagate Barracuda Pro) are the only way forward for 24/7 duty.

Technical Highlights:

• Quad-core Xeon E-2414 (2.6GHz): Single-socket design keeps thermal density manageable and power consumption fixed at 290W. Real-time video decode and VMS event processing handle mid-scale camera groups without spilling to async I/O.
• 16GB DDR5 UDIMM: Sufficient memory for a full VMS stack (Milestone, Genetec, or equivalent) plus simultaneous playback and live view on 8–16 streams. No need to buy oversized RAM; this is the sweet spot for this processor class.
• Two LFF (3.5-inch) drive bays with onboard RAID: RAID 1 gives you fault tolerance; RAID 0 gives you raw capacity. Either way, the controller is embedded—no separate HBA card required. Total raw capacity depends on drive size (2×18TB is common), but stick with enterprise-class drives rated for continuous operation.
• 290W single power supply: No redundancy at the PSU level, but the wattage is sufficient for the Xeon E-2414 plus two large drives with thermal margin. If you need N+1 power, deploy an external UPS or step to a larger chassis.
• PCIe Gen5 x16 and 1 OCP 3.0 slot: Add a 10GbE NIC for high-bandwidth camera ingest if needed, or plug in an OCP storage/management card. Future-proofing without taking up your only expansion slot.

Deployment Considerations:

• This is a single-socket design with no PSU redundancy. If uptime is mission-critical, pair it with a UPS or deploy a second unit in an active-passive failover config with shared storage.
• The two LFF bays are your limit—no room to grow beyond 2 drives without migrating to a larger chassis. Plan your RAID strategy (and drive capacity) upfront; adding a third drive later means a new server.
• Thermal design assumes front-to-back airflow in a proper server rack. Don't stack equipment or restrict intake vents; a single overheating drive can corrupt the RAID mirror and take both drives offline.
• The embedded dual gigabit NICs are adequate for standard IP camera feeds, but if you're pulling large-file backups or multi-site replication, invest in the PCIe Gen5 10GbE NIC card immediately.

This server shines in small warehouse, retail, or education deployments where you need compact footprint but real fault tolerance. It's not a one-size-fits-all NVR appliance, and it's not designed for 50+ camera mega-deployments—but for 8–16 cameras with RAID 1 backup and 24/7 recording, the P65393-B21 is the efficient, cost-effective choice.
