HPE DL580 GEN10 8SFF HDD BAY KIT - 878366-B21

HPE 878366-B21 DL580 Gen10 8-Bay SFF HDD Bay Kit

Overview

The HPE 878366-B21 is an internal hard drive bay expansion kit for the HPE ProLiant server platform, specifically engineered to add an 8-bay Small Form Factor (SFF) hot-plug drive cage to the DL580 Gen10. If your DL580 Gen10 shipped with fewer drive bays than your workload demands — dense database, virtualization, or network video recording with high channel counts — this kit closes that gap without requiring a chassis swap. The 878366-B21 slots into the server's designated bay expansion location, enabling up to eight additional 2.5-inch SFF drives to be installed and managed within the existing chassis footprint.

Compatibility

Designed exclusively for the HPE ProLiant DL580 Gen10 four-socket server. This kit is not cross-compatible with DL580 Gen9, DL560, DL380, or other ProLiant families — the mechanical bay geometry and backplane connectors are generation- and model-specific. Confirm your server's current bay configuration and available expansion slots in the chassis before ordering; the DL580 Gen10 supports multiple bay kit configurations and the available slot depends on the base server option purchased. Compatible drives are 2.5-inch SFF SAS/SATA hot-plug units supported under the HPE DL580 Gen10 storage options matrix — verify drive compatibility against HPE's QuickSpecs for the DL580 Gen10 before populating the cage.

Installation Notes

The kit weighs 2.80 lb and measures 7.50 × 5.30 × 2.60 inches, consistent with a tool-less or minimal-tool slide-in cage assembly typical of HPE ProLiant accessory bay kits. Installation requires the server to be powered down and removed from the rack for safe bay access. No drives are included — the 878366-B21 provides the cage, backplane, and mounting hardware only. Populate drives after the cage is seated and secured. Source from genuine HPE-compatible storage to maintain warranty and support coverage on the host server.
