ProLiant Microserver Parts

The ProLiant Microserver is the smallest machine in the ProLiant range: a compact single-processor box built to sit on a desk or a shelf, with its drives in an internal cage behind a front door rather than in hot-plug carriers across the face of a chassis. It is a ProLiant by firmware and by parts discipline, but almost nothing about its hardware is shared with the rack and tower lines. Every part on the model pages below is genuine HPE, available new and refurbished, and tested for compatibility before it ships.

What Defines a ProLiant Microserver

• Unbuffered memory, not registered: this is the mistake that costs people a return. Microserver models take unbuffered modules, while the DL and ML servers mostly take registered DIMMs, so a spare DIMM out of a rack server will not work here. Check the module type listed on the page for your model.
• One power supply: a single internal unit, not a hot-plug redundant pair. There is no second supply to fail over to, and there is no supply bay to populate.
• Drives live inside: a small fixed number of internal bays behind the front door, reached by opening the chassis rather than by pulling a carrier out of the front. The count depends on the model.
• One processor per machine: so memory and storage are the practical upgrade path, and the processor is not always a separately listed part.
• Built to sit out, not to rack: the chassis is designed for a desk or a shelf. A small number of rack options are listed for the Gen8 machine, but the family is not a rail-mounted design.
• What the listings carry: drives, memory, storage controllers, media and USB or SD options dominate, which matches how these machines are used — as small file, backup and lab servers rather than as expansion platforms.

A spare DIMM out of a rack server is the classic Microserver mistake. These machines take unbuffered modules, while the DL and ML servers mostly take registered DIMMs, so the two do not substitute for each other. Check the module type listed on the page for your model before ordering memory.

• ProLiant Microserver G1 — the first Microserver generation, the compact box that started the line.
• ProLiant MicroServer Gen8 — the Gen8 machine, and the largest of the three listings: memory, drives, storage controllers, networking, media and USB or SD options.
• ProLiant Microserver — the Microserver listing that is not split by generation, covering drives, memory, media, remote management and backup options.

If the machine is a floor-standing tower rather than a compact box, its parts are in ProLiant ML Tower Server Parts, and anything rail-mounted is in ProLiant DL Rack Server Parts. Blades that need an enclosure are in ProLiant BL Blade Server Parts, and ProLiant models that predate the lettered naming are under HPE Retired Model Server Parts. Every family sits under HPE parts by server model.

ProLiant Microserver Parts FAQ

Can I use memory from a rack server in a Microserver?
No. Microserver models take unbuffered modules, while the DL and ML servers mostly take registered DIMMs. Check the module type listed on the page for your model before ordering.

How many drives does a Microserver hold?
A small fixed number of internal bays behind the front door rather than a hot-plug cage. The exact count depends on the model, so check the page for the machine you own.

Does a Microserver have redundant power?
No. It runs a single internal power supply with no second unit to take over. That is one of the main design differences from a rack or tower ProLiant.

Can a Microserver be rack mounted?
It is built to sit on a desk or a shelf rather than on rails. A small number of rack options are listed for the Gen8 machine, so check the page for your model.

Which Microserver page should I use?
Pick the one that matches the generation on your chassis label. There is a page for the G1 machine, a page for the Gen8 machine, and a general Microserver listing that is not split by generation.

Is the processor upgradable?
Treat memory and storage as the upgrade path. A Microserver carries one processor, and on some models it is not listed as a separate part.
