ProLiant XL Server Parts

A ProLiant XL is a server tray, not a standalone server. It carries processors, memory, drives and its own management, and slides into a shared Apollo chassis that supplies the power and cooling for several trays at once. The family is built for density: the chassis does the heavy work so that each tray can be mostly compute. Every part on the model pages below is genuine HPE, available new and refurbished, and tested for compatibility before it ships.

What Defines an XL Server Tray

• No power supply and no fans on the tray: both are chassis hardware and are shared between trays, which is why an XL listing carries no power supply part numbers.
• The chassis is what mounts in the rack: rails and rack hardware belong to the chassis, and the trays slide into it from the front.
• A tray is built for one chassis: depth, connector position and power delivery are specific to the chassis it was designed for, so identify the chassis as well as the tray before ordering.
• Expansion is a riser and a mezzanine, not a cage: the XL230a Gen9 listing carries riser cards, which is the shape expansion takes in a tray — one or two slots, chosen at build time.
• Fabric matters more than slots: these machines are bought by the rack for high-performance computing, and the XL730f Gen9 listing includes InfiniBand adapters alongside its memory and drives.
• Drives travel with the tray: each XL model in this family lists its own drives, so a drive is tied to the node that holds it rather than to a shared pool in the chassis.

An XL tray is built for one chassis, and the chassis is the half that plugs into the rack. Power and cooling come from the chassis and are shared between trays, which is why an XL listing carries no power supply part numbers. Depth, connector position and power delivery are specific to the chassis the tray was designed for.

The ProLiant SL Scalable Server Parts family is the closest relative, with the same tray-in-a-chassis design under an earlier model prefix, and ProLiant DL Multi Node Server Parts covers several nodes in one rack chassis. If the machine has its own power supplies and rails it is a standalone server, so see ProLiant DL Rack Server Parts; blades that need an enclosure are in ProLiant BL Blade Server Parts. Every family sits under HPE parts by server model.

ProLiant XL Server Parts FAQ

What is an XL server?
A server tray. It carries processors, memory, drives and management, and slides into a shared Apollo chassis that supplies power and cooling for several trays at once.

Does an XL tray have its own power supply?
No. Power and cooling come from the chassis, which is why the tray listings carry no power supply part numbers. A power fault is a chassis-level part.

Can an XL tray go into any chassis?
No. Each tray is designed for a specific chassis, and depth, connector position and power delivery all vary. Identify the chassis as well as the tray before ordering.

What is the difference between the XL220a Gen8 v2 and the XL230a Gen9?
Generation, and what each listing holds. The XL220a Gen8 v2 page covers memory, drives, storage controllers, networking, rack options and USB or SD options; the XL230a Gen9 page covers drives, networking, storage controllers and riser cards.

Why does the XL730f Gen9 listing include InfiniBand?
Because the tray is aimed at high-performance computing, where InfiniBand is a common fabric. Its listing covers memory, drives and InfiniBand adapters.

Are XL and SL trays interchangeable?
No. They are separate families designed for different chassis. If the model number on your tray starts with SL, use the ProLiant SL pages instead.
