774026-001 3.5" Drive tray Caddy fit HP Apollo 4200 4510 Proliant DL325 ML110 Gen10

• The HPE 774026-001 is an official 3.5-inch Large Form Factor (LFF) drive tray/caddy (also known as a drive carrier or sled) designed for hot-plug SAS/SATA hard drives and SSDs in select HPE ProLiant and Apollo servers.
• This tray securely mounts a standard 3.5" drive into the server's front drive bay, providing mechanical support, hot-plug capability, electrical connection, and proper airflow alignment for reliable operation in enterprise storage configurations.
• It is compatible with multiple HPE server generations and models that use 3.5" LFF hot-plug drive bays, including the HPE Apollo 4200, HPE ProLiant DL325 Gen10, HPE ProLiant ML110 Gen10, HPE ProLiant DL380 Gen10, HPE ProLiant DL360 Gen10 (with 3.5" backplane option), HPE ProLiant ML350 Gen10, and several other Gen9/Gen10 LFF servers.
• The 774026-001 is a tool-less or thumb-screw style tray (depending on exact revision), featuring a black plastic carrier with metal latch/handle, drive mounting points (screws usually pre-installed or included), and alignment keys to ensure correct insertion and hot-plug detection by the server backplane.
• Reliability is ensured by HPE-certified design, precise tolerances for vibration resistance, secure latching to prevent accidental ejection, and full validation with HPE backplanes and controllers (Smart Array/PERC) for hot-plug, RAID recognition, and status LED functionality.
• Available primarily as refurbished or used units (as this is a mature part from ~2017–2020 era), refurbished trays are widely sold, tested for fit and latch function, and often pulled from decommissioned HPE servers.
• HPE originally provided limited warranty on new trays (now expired); refurbished market options vary by seller (typically 30–90 days); eco-friendly through reuse of hardware and RoHS compliance.
• As an HPE-branded 774026-001 3.5" LFF drive tray, it is a direct, drop-in replacement for the listed servers (Apollo 4200, DL325 Gen10, ML110 Gen10, etc.) to support standard 3.5" SAS/SATA HDDs/SSDs.
