It replicates the mechanical fit and mounting geometry of the original HP hot-swap caddies, allowing you to use standard 3.5" SATA/SAS drives in HP server drive bays.
This design was created specifically to:
Provide a low-cost replacement for expensive OEM HP caddies
Work seamlessly with Gen8 / Gen9 hot-swap drive bays
Integrate with my custom 1U tray system and compatible storage setups
Key Features
✅ Compatible with HP ProLiant Gen8 / Gen9 3.5" bays
✅ Supports 3.5" SATA and SAS drives
✅ Designed for hot-swap use in supported backplanes
✅ Lightweight, fully 3D printable design
✅ Optimized for strength and repeated insertion/removal
✅ Works with standard HP server rail mechanisms
⚠️ Important Notes
This model is a mechanical replacement caddy only.
To achieve full hot-swap functionality, your system must include:
A hot-swap capable HP backplane (Gen8/Gen9 compatible)
A compatible SATA/SAS controller with hot-plug support
Proper server firmware / BIOS configuration
The caddy itself does not provide electronics, LED control, or drive intelligence.
Some servers may show warnings (e.g. “non-original drive”) but functionality is typically unaffected.
Printing Recommendations
Material: PETG / ABS / ASA recommended
Layer height: 0.2 mm
Walls: 3-4
Infill: 15-30%
Print orientation: face down
if you can print multi material, doing petg with the supports in pla leaves far nicer result as it has some big overhangs.
Use Cases
HP ProLiant Gen8 / Gen9 homelabs
DIY NAS / storage servers
Replacement for missing OEM caddies
Data hoarder / server rebuild projects
Integration with custom rack storage systems
Notes
Designed to pair with my custom 1U tray and HP-compatible storage system, enabling a full modular homelab storage setup without relying on expensive OEM parts.
