Description
Overview
The HP 2.5‑inch Tray (caddy) is an essential component for HP ProLiant servers in the G7, G8, and G9 generations. Designed specifically for 2.5‑inch SAS or SATA hard drives and SSDs, this hot-swap carrier gives you the flexibility to easily install, replace, or upgrade storage drives without turning off your server. Built with a sturdy metal frame and durable plastic parts, the tray ensures reliable drive retention, even in high-vibration or heavily accessed rack environments.
This caddy integrates perfectly with HP’s SmartDrive or Smart Carrier system, aligning securely with the server backplane to maintain consistent power/data connections and support activity/health LED indicators. The tool-free mounting design simplifies installation, allowing IT teams to quickly swap drives during maintenance or scaling operations. With full support for HP ProLiant G7, G8, and G9 servers, it helps maintain compatibility across multiple system generations — ideal for data centers that are upgrading incrementally or reusing existing hardware. Whether you’re building out new storage arrays, replacing a failing drive, or simply standardizing your caddies across servers, this tray offers performance, reliability, and ease of use.
