HPE DL560 NVME 8 SSD Express BAY KIT - 872225-B21

HPE 872225-B21 NVMe 8-SSD Express Bay Kit

Overview

The HPE 872225-B21 is an eight-drive NVMe SSD Express Bay Kit designed to expand direct-attach NVMe storage capacity in HPE ProLiant DL560 servers. Where traditional SATA or SAS backplane configurations bottleneck on shared bus throughput, this kit provisions eight dedicated NVMe lanes — each SSD communicates directly with the PCIe fabric, eliminating the protocol translation overhead that constrains SAS/SATA arrays. The result is lower latency and higher sequential throughput per drive, which matters in workloads like NVR-scale video recording, AI inference pipelines, and high-transaction databases where storage becomes the constraint before compute does. At 2.40 lb and 3.75 × 11.00 × 15.50 in, the kit is a purpose-built mechanical assembly sized to the DL560 chassis — not a generic bracket.

Compatibility

The 872225-B21 is designed for the HPE ProLiant DL560 server platform. Verify chassis generation and NVMe backplane requirements against your specific DL560 configuration before ordering — HPE ProLiant accessory kits are generation-matched and are not interchangeable across chassis revisions. Compatible NVMe SSDs must be sourced separately; this kit provides the bay infrastructure only. If you are building out a high-density server storage configuration, confirm that your DL560 system board and riser topology support the full eight-bay NVMe population before provisioning drives. The UNSPSC code 43211600 classifies this as a computer storage device component — consistent with bay/backplane hardware.

Installation Notes

Installation requires access to the DL560 chassis interior following HPE's standard ESD precautions. The kit dimensions (3.75 × 11.00 × 15.50 in) indicate a full-depth internal assembly — plan for a complete server shutdown and chassis opening. No tool or torque data is specified in available evidence; consult the HPE DL560 Maintenance and Service Guide for torque specs and drive bay population rules before installation. Confirm firmware compatibility between the NVMe backplane and server system ROM prior to populating drives, as HPE NVMe configurations may require specific SPP (Service Pack for ProLiant) levels to enumerate all eight bays correctly.
