875091-001 HPE DL380 Gen10 4-Port Riser Board inc. cable

HPE Quad-Port Cage Board inc. Cable Overview

The HPE 875091-001 DL380 Gen10 Quad-Port 8 NVMe Slim SAS Riser Cage Board inc. Cable category groups together the essential storage expansion and riser components specifically engineered for the HPE ProLiant DL380 Gen10 platform. This category covers original equipment manufacturer (OEM) riser cages, slim SAS backplanes, quad-port NVMe risers, and the matching cable assemblies required to add or replace NVMe/SAS drive cages. Pages in this category aim to help IT buyers, system integrators, data center operators, and hardware refurbishers identify compatible parts, understand technical specifications, compare options, and follow proven installation and maintenance practices to maximize server uptime and storage performance.

Key Features

Quad-Port NVMe Support and Slim SAS Architecture

At the heart of the HPE 875091-001 product family is support for high-density NVMe deployments via a quad-port riser cage design. These riser cages are shaped to accept up to eight NVMe slim SSDs or SAS devices depending on the specific backplane and cable configuration. The slim SAS form factor allows servers such as the HPE ProLiant DL380 Gen10 to house more drives in the same 2U footprint, enabling greater storage capacity and I/O density without increasing rack space. The quad-port design typically routes four NVMe lanes per connector, delivering high throughput and low latency to support virtualization, database workloads, and high-performance computing.

Included Cable

The phrase "inc. Cable" in the product title indicates the inclusion of the necessary slim SAS / NVMe cables and harnesses that connect the riser cage to the server backplane or HBA/controller card. Using OEM-matched cables reduces compatibility issues and ensures signal integrity at NVMe speeds. Included cable assemblies are usually pre-tested and marked for polarity and port assignment, which speeds up installation and minimizes troubleshooting time in production environments.

Form Factor

Riser cage boards like this model are manufactured to HPE mechanical specifications for the DL380 Gen10 chassis. Typical characteristics include precision-machined mounting points, EMI shielding where required, connectors aligned to the chassis drive sleds, and integrated retainers to secure slim drives. The form factor is optimized for airflow and thermal dissipation so that NVMe devices — which can generate significant heat under sustained load — operate within rated temperature envelopes.

Compatibility

Supported Servers and Chassis

This category focuses on parts compatible with the HPE ProLiant DL380 Gen10 series. Items include direct-fit replacements for Gen10 models and variants that may require minor firmware or BIOS updates to be fully recognized. Before purchasing, confirm the server's chassis revision and existing drive cage layout — some DL380 submodels ship with different backplane options (NVMe vs. SAS/SATA) and drive carrier types which determine the exact riser and cable assembly required.

Controller and HBA Interoperability

The riser cage communicates with NVMe drives through the server's NVMe-capable HBA or the system board's integrated NVMe lanes. Ensure your HBA or RAID controller supports NVMe passthrough or appropriate NVMe namespaces when planning deployments. For mixed SAS/NVMe environments, verify that the controller supports both protocols or that you have separate controllers dedicated to each storage type.

Performance

Maximizing NVMe Throughput

The combination of the HPE 875091-001 quad-port riser and appropriate NVMe drives can deliver very high I/O throughput. For best results:

• Use enterprise-grade NVMe SSDs with proven endurance and thermal characteristics.
• Ensure the server BIOS and HBA firmware are updated to the latest recommended versions for NVMe support.
• Monitor temperatures and configure appropriate cooling and fan profiles in HPE iLO or chassis management tools.
• Balance workloads across NVMe namespaces where possible to prevent single-device bottlenecks.

Use Cases

High-Performance Databases & Transactional Systems

The DL380 Gen10 populated with HPE 875091-001 riser cages is ideal for latency-sensitive database workloads (OLTP, NoSQL), where NVMe's low latency and high IOPS significantly improve transaction response times and concurrency.

Virtualization & VDI

Virtual desktop infrastructure (VDI) and dense VM deployments benefit from NVMe storage tiers for boot and application volumes. The quad-port, 8-drive capacity enables compact, dense storage tiers within a single 2U chassis.

Cache/Tiered Storage for Hybrid Architectures

Use NVMe drives in caching tiers in front of larger SAS/SATA arrays to accelerate frequently accessed datasets. The included cable and riser harness make integrating fast NVMe tiers into existing DL380 Gen10 systems straightforward.
