HPE DL325 G11 8SFF X1NVME U.3 OCP2 CA - P59619-B21

HPE P59619-B21 DL325 Gen11 8SFF NVMe U.3 OCP2 Cable Assembly

The HPE P59619-B21 is a factory-new cable assembly designed for the HPE ProLiant DL325 Gen11 server platform, specifically enabling a single NVMe U.3 drive connection routed through an OCP 2.0 slot. If you are expanding storage connectivity on a DL325 Gen11 configured with the 8 Small Form Factor (8SFF) drive bay arrangement, P59619-B21 (often searched as P59619 B21) is the OEM-matched cable that ensures signal integrity without improvised wiring.

Overview

The DL325 Gen11 is HPE's single-socket AMD EPYC server, and storage cabling in dense SFF configurations is platform-specific — off-brand or mismatched cables risk negotiation failures, unsupported topologies, or voided support agreements. This assembly provides the U.3 NVMe pathway from the 8SFF backplane to the OCP 2.0 slot, a routing option relevant when deploying NVMe-accelerated workloads such as high-throughput video retention, AI inferencing storage, or database tiers where NVMe latency matters.

Key Features

• Platform-Matched Design: Built specifically for the DL325 Gen11 8SFF chassis — connectors, routing length, and locking retention are validated against HPE's own backplane and OCP 2.0 riser geometry, reducing fitment risk during installation.
• U.3 NVMe Connectivity: U.3 is the unified form factor that supports NVMe, SAS, and SATA protocols over a single physical interface — meaning this cable keeps your storage topology flexible as drive generations change, without requiring a backplane swap.
• Compact 0.10 lb Profile: At 0.10 lb, this assembly adds negligible weight to the chassis — a non-issue in rack-density planning but worth confirming if you are near a per-rack weight limit in a dense deployment.
• Multi-Country Production: Manufactured across HPE's global supply chain (CN, CZ, JP, MX, SG), consistent with HPE's standard enterprise server accessory sourcing model.

Integration & Compatibility

This cable is validated for the HPE ProLiant DL325 Gen11 in the 8SFF drive bay configuration with a single NVMe U.3 drive and OCP 2.0 slot. Confirm your server's exact bay and riser configuration against HPE's HPE server accessories compatibility matrix before ordering — the DL325 Gen11 supports multiple storage configurations, and the cable routing differs across them. Pairing with other rack server components outside the validated DL325 Gen11 8SFF platform is not supported by this part number.

Frequently Asked Questions

Q: What server platform is the P59619-B21 designed for?

A: The P59619-B21 is designed for the HPE ProLiant DL325 Gen11 server in the 8 Small Form Factor (8SFF) drive bay configuration, providing a single NVMe U.3 connection via OCP 2.0.

Q: Is the P59619-B21 compatible with DL325 Gen10 or other ProLiant models?

A: Based on available evidence, this cable assembly is validated for the DL325 Gen11 8SFF platform. Compatibility with Gen10 or other ProLiant models is not confirmed in the source data — consult HPE's compatibility guide for your specific server generation before ordering.

Q: What does U.3 mean for storage flexibility?

A: U.3 is a unified storage interface that supports NVMe, SAS, and SATA drives over the same physical connector. This means the cable remains usable as you transition drive types within the supported backplane, without requiring a cabling change.

Q: Is the P59619-B21 a genuine HPE part?

A: Yes. This is a factory-new, genuine HPE component sourced through distribution — not a third-party or aftermarket cable assembly.

Karl Wilson

The P59619-B21 is one of those parts that looks trivial on paper — a 0.10 lb cable assembly — but gets consequential fast when you are commissioning an HPE DL325 Gen11 8SFF system for a storage-intensive workload and the NVMe U.3 OCP2 path is not routed correctly. Using anything other than the OEM-matched cable in this slot introduces risk that HPE support will not cover, and NVMe negotiation failures on mismatched cabling are notoriously difficult to diagnose under load.

Technical Highlights:

• OCP 2.0 NVMe routing: Routes a single U.3 NVMe drive through the OCP 2.0 slot — the validated path for NVMe acceleration on the DL325 Gen11 8SFF, where the alternative storage lanes are already occupied by SFF bays.
• U.3 protocol flexibility: U.3 physical interface supports NVMe, SAS, and SATA over the same connector — so this cable does not lock you into a single drive protocol as your storage strategy evolves.
• 0.10 lb assembly: Negligible weight contribution to the chassis; relevant only when calculating total rack weight for high-density deployments where every component is tracked.

Deployment Considerations:

• Verify your DL325 Gen11 is specifically in the 8SFF bay configuration before ordering — the Gen11 platform supports multiple storage configurations, each with distinct cabling part numbers; ordering the wrong cable means a return, not a workaround.
• This cable enables one NVMe U.3 device via OCP 2.0; if your design calls for multiple NVMe paths or a different backplane topology, you will need additional or different HPE cable SKUs validated for that configuration.

Best fit for DL325 Gen11 8SFF deployments where a single NVMe U.3 drive is being added through the OCP 2.0 slot — common in edge AI inferencing nodes, video analytics servers, or tiered storage builds where one fast NVMe tier complements the SFF SAS/SATA pool.
