Homeserver - ESXi on HPE ProLiant MicroServer Gen10

After Hewlett Packard Enterprise has missed offering a Microserver in their 9th Generation, it is now back in Gen10. The Microserver series provides affordable servers intended to be used in SMB and as home servers. Due to its low price and power consumption, you can find this system in many virtualization home labs as ESXi hosts or Storages.

The HPE ProLiant MicroServer Gen10 is available with two different CPUs - AMD Opteron X3216 and X3421. Both models a SoC which means that the CPU cannot be changed like the Intel CPUs in Gen8. They support up to 32GB of unbuffered DDR RAM. The server can be equipped with 4 hard drive from the front.

  • HPE ProLiant MicroServer Gen10, Opteron X3216 (2x 1.6 - 3.0GHz / 15W TDP)
  • HPE ProLiant MicroServer Gen10, Opteron X3421 (4x 2.1 - 3.4GHz / 35W TDP)


Gen10 Microservers are shipped with the following configuration:

  • Processor:
    AMD Opteron X3216 Processor (2x 1.6-3.0GHz / 1MB / 12-15W) or AMD Opteron X3421 Processor (4x 2.1-3.4GHz / 2MB / 12-35W)
  • Memory: Up to 32GB DDR4 Unbuffered UDIMM
  • Expansion Slots: 1x PCIe 3.0 x8 Low Profile, 1x PCIe 3.0 x4 Low Profile
  • HDD Bays: 4 HDD bays (Front)
  • Media bay: (DVD or SSD)
  • Ports: 2x USB 2.0, 4x USB 3.0
  • Network: 2x 1Gbit LAN (Broadcom BCM5720)
  • Storage Controller: Marvell 88SE9230
  • Power Supply: 200 Watt, non-redundant
  • Internal Ports: 1x USB 2.0, 1x SATA III

The Kit is shipped with Hard drive screws that allow installing Hard Drives without bays.

HCL and ESXi Support

The Gen10 Microserver is currently not listed in the HCL and thus not officially supported. The Gen8 version was listed, so there might be a chance that the Gen10 will be listed in the future.

Despite it is not supported, ESXi runs out of the box with the following ESXi versions:

  • ESXi 6.5
  • ESXi 6.0
  • ESXi 5.5

Delivery and assembly

The server is very handy and fits easily on or under a desk. Compared to Gen8, the front is no longer a door, but a removable lid. Memory slots are accessible without removing the mainboard. To install PCI Card, the mainboard has to be removed, which is quite easy. Just remove one screw in the back and pull it out like in previous versions.

To install hard drives simply use the Hard drive screws (located above the slots) and plug them into the slots. If you have 2.5" drives, most available 2.5" to 3.5" HDD adapter will work too.


As mentioned, there is no remote management in the Gen10 microserver which means that physical access is required to install ESXi. The installation works without problems with both, the standard ESXi Image, and an HPE customized Image. However, there is no sensor support so the standard image should be fine. The System has been tested with ESXi 6.5, ESXi 6.0 and ESXi 5.5.

Power consumption

Microservers have a very low power consumption. I'm using an X3216 with 4 HDDs as shared storage using FreeNAS which averages at about 50W. With that, the average operating costs are at about 11 Euros per month:
50 watt * 24 h * 30 (days) = 36 KWh * 0,30 (EUR) = 10,80 EUR
Consumption measured with Voltcraft Energy Monitor 3000


The HP Proliant Gen10 is a solid upgrade from previous versions but comes with less flexibility in terms of CPU and the lack of a remote management is a step backward. With two or three Systems you can build a reliable homelab and start to play around various VMware features. I recommend buying the X3421 because of the faster CPU. The X3216 is better suitable to be used as storage with FreeNAS for example. With the Gen10 Microserver, you can create a cluster, play with vMotion, HA, DRS and resource pools or even create your personal vCloud or VDI environment. When you have an additional SSD, you can use vSAN to transform the local storage into redundant shared storage. The server is very silent and can run near your desk.

  1. Thank you for this article, especially the performance comparison and the power consumption is very helpful!
    I'm a little bit disappointed about the lack of iLO interface and the fact that there is no microSD card slot as well.

    1. Yes, the missing iLO is a bit of a shame. The missing microSD slot is not a big deal for me personally as the internal USB slot is a usable alternative.

  2. Does the box also support IOMMU/AMD-Vi (equivalent to Intel's VT-d)? I've been thinking of buying one of these boxes but since I can't find an answer anywhere this is what's stopping me.

    1. Hi Jeroen,
      I was just playing with it this weekend (the dual core version).
      On ESXi 6.5 I was able to pass-through the Marvell 4xSata controller to a VM (OMV3.x). Works like a charm. Just make sure it is enabled in BIOS.
      One note, I am not missing iLO as I was not willing to pay for it on my Gen 8 homelab anyway :)
      Without hard drives I noticed it was idling in Linux on 12-15W which is a 10-15W better then the Gen 8 as far as I remember..

  3. Did you try performance test on storage side? Because on Gen8 there are some tests and difference based on the hp sas controller version.. Did you use the integrated controller with a raid1? I notice that there is as optional, the HPE Smart Array E208i-p SR Gen10 Controller available. Could be better?
    Another question, could be problems if a migrate a fully functional vm from a intel based server to this? (I would like to use this as a small disaster recovery solution).

  4. Hello - First sorry for my English :/
    I'm want to buy a NAS for use at home, with wireless keyboard/mouse connected to TV - I was planning to buy QNAP TS-453A, with HDMI output - but after testing a HD station I'm not happy - then I found this server, and I'm thinking, that this server, with Windows 10 could be more usefull than any lunux-based systems - especially for my Wife :) Now I have a Asrock barbone PC with Windows 10 - works great, but I need also some storage.
    What do You think about my idea ? What about drivers ?

  5. can you do gpu passthrough to a windows vm (esxi, xen or kvm - whatever)? so you can have the barebones hypervisor but connect gpu/mouse/keyboard to a windows guest

  6. Hello, just to tell you that I just installed
    6.7.0 Update 2 (Build 13006603) in HPE ProLiant MicroServer Gen10, Opteron X3421 8GB on Ram, The ISO was download, directly from the VMWARE site.

  7. Hi ,
    I have just installed esxi6.7. I boot it from the sata port.
    I can't get "passtrough" of the disk controller to work for the raid controller.

    There no device that is passthrough compatible.

    Any idea?

    1. Same here, installed HPE customized image, ESXi 6.7U2. Works like a charm. Only problem I see is that "passthrough" of any USB device doesn't work either. It says, indeed, that none of the PCI devices is passthrough compatible.

  8. Wonderful little boxes these are. I've only run into one minor hurdle, which is being able to monitor the RAID status from, say, Ubuntu 18.04.LTS. I cannot for the life of me figure out how that should be done. And monitoring the RAID seems like a pretty basic thing you'd want to do :-)

  9. For anything linux, run native linux softraids ie MADAM or other items like BTRFS with email alerts. I do this for older Gen 8 microservers too... just run in SATA AHCI mode, not Marvell raid mode so linux manages the disks directly.

  10. Hi, I am trying to enable hardware passhtrough for the PCI- HDD's to a VM directly. However I cannot set these options even when I put the Esxi in Maintainance mode, it just says not capable. and I don't know what to enable in the bios to get it to work, could you tell me please?

  11. Hi, sorry to drag up an old post. Can anyone tell me how it's possible to monitor the Marvell RAID health? EXSi won't see it in the health section. Thanks
