HP ProLiant MicroServer Gen8 – Real World Usage

You may have read my previous blog post, covering an initial overview of the HP ProLiant MicroServer Gen8. I’m still very happy with the hardware as a whole, but had some issues in updating firmware using the Intelligent Provisioning OS. First, if you want to get the latest (at time of writing) version of Intelligent Provisioning 1.40, you can download a 921mb ISO of it it from here: hp.com

My home internet is rather slow, and I think this was the main issue with the firmware update process timing out. I decided to download an iso of all firmware for the server called HP Service Pack for ProLiant 2013.09.0 (B), which you can also download from here: hp.com – note you have to sign up for a hp account first, and the download is 2.9gb.

I was able to install Windows Server 2012 R2 using Intelligent Provisioning, which nicely installs all the required drivers without you having to think about it and that worked perfectly.

Getting the lid of the case off and on was very simple to do, just two thumb screws at the back lets you lift the entire sides and top off in one piece. You can access pretty much everything internally you need to at that stage due to the convenient design.

Next up, by default the server can take 4 x 3.5″ HDDS, and a 9.5mm CD/DVD drive. Luckily this means if you don’t need the CD/DVD drive, you can have an extra 2.5″ HDD as your OS install, leaving the other disks for your actual data. A good idea since you can use the remaining SATA port on the motherboard, but there’s no spare SATA power cable, as the CD/DVD drive uses the old style floppy disk power connector (as per the green arrow on the photo below). There’s a molex connection nearby (red arrow) so I pulled that through the gap, and added on a double adapter on the molex, then added a molex > sata adapter to finally get power to the extra hard drive.


When I had a drive in the first bay, the server decided that was the preferred boot device. To fix that, I changed the boot order to use the second SATA controller first, as it seems the spare SATA port on the motherboard is connected to that. The first controller goes to the first two HDD bays, and they run at 6Gb/s, compared to the 3Gb/s of the 3rd and 4th bays plus the separate onboard SATA port. This is worth keeping in mind for what drives and data you plan to configure.

As mentioned in the previous blog post, there is a MicroSD slot on the motherboard as well as an internal USB port – neither are useful for a Windows OS unless you’re using Windows To Go. The MicroSD is a bootable device, but also it’s handy as a swap drive or pagefile. Other OS’s that support running off a USB such as ESXi can be used too.

The hard drive bays aren’t hot swappable (unless you buy a separate RAID card, put that into the single empty PCIe 2.0 slot, and connect the drive bay to that instead), but that’s not really a problem anyway. They are quite easy to use, so at least when you have to add or remove a hard drive, you won’t have any physical complications.

For the RAM, I first tried a few sticks of NON-ECC DDR3 sticks, but the server wasn’t happy with those (one was even HP branded). After putting in the first ECC stick I could find, it worked and was bumped up to 4GB. I’m not planning on running VM’s off this thing, so that’s plenty for me.

On the switch side of things, the HP PS1810-8G is a nice fit. Resting on top, it moved ever so slightly when pushed down on so I decided to put it below the server instead, and it is now rock solid. It’s fanless, so you won’t hear it. It can also be powered by PoE, which isn’t very useful in a small business environment, but would be useful if you had an upstream PoE switch – which in that case, you wouldn’t have this MicroServer on top or below it. Regardless, there’s no harm in it being there :) Either way, It runs at 7.2 W maximum, so it’s drawing even less power than many of the standard power saving  compact fluro bulbs.

The web interface is plain but very useful with a decent amount of options.

Instead of running three separate network cables to the server, it is nice just to run one to the switch, then have three cables going up to both NIC ports and the iLO, which makes it much more self contained.

Over at GeekZone, Mauricio Freitas has also been playing with the HP server, and had a thread about it along with pictures. Worth having a look. I also found a thread at avforums.com which had more great info, and there seems to be a configuration consideration around trying to use the spare SATA port on board (used for the CD/DVD Drive) as a boot device when the HDD bays are fully populated. I agree with the fix of adding in a PCIe Sata controller, which will then let your extra hard drive be bootable. This in turn could allow you to attach an SSD to the 5th internal SATA port, and then with Windows Server 2012 R2’s tiering options you’d have a pretty decent HDD setup!

Pricing – there’s no RRP that I can find, but you’re looking around the $500 mark. Shop around of course.

So, it’s still a great bit of kit, but as with most things there’s a lot of considerations and adjustments to be made to make it fit exactly how you want – but that’s where the fun is.

HP ProLiant MicroServer Gen8 Overview

Many of you would have heard of, if not used, one of HP’s ProLiant MicroServers. They are relatively cheap cubes of servery goodness, designed to do a much better job than just a standard desktop box. HP released a few months ago the Gen8 version which has a bunch of new features. Cosmetically I think it looks a lot nicer than the older models, and it’s also really simple and smooth to take apart. It’s also closer to being a proper cube than previous models, shorter and stockier.


Why get this instead of a normal desktop? It’s low powered (150w), has two NICs onboard, Hot Swap hard drive bays (holding up to four drives, supporting 0/1/10 RAID), and an ILO 4 connector. For a small business, this means you’ll have your data on redundant drives, can double your throughput via the second NIC (NIC Teaming in Windows Server 2012 is awesome and easy) and if you can’t get to your server for some reason, the iLO 4 is HP’s Management Engine that will let you both monitor the server and connect to it, as long as you’ve got power and a network cable plugged into the ILO port. The iLO 4 interface has a lot of management options, and some interesting things like a 3d heat map!


There’s even an Android and iOS App for iLO (screenshot from my Samsung Galaxy S3, using Remote Control) – just another cool little feature.


I’m testing the Base Model rather than the Entry Model, detailed specs available here hp.com (check the Pre-configured Models)

  • Processor (1) Intel® Pentium® G2020T (2.5GHz/2-core/3MB/35W) Processor
  • Cache Memory 3MB (1 x 3MB) L3 cache
  • Memory 2GB (1 x 2GB) PC3-12800E DDR3 UDIMM
  • Network Controller HP Ethernet 1Gb 2-port 332i Adapter
  • Storage Controller HP Dynamic Smart Array B120i Controller
  • Hard Drive 500gb SATA2 (no hard drive standard, added on)
  • Internal Storage 4 LFF NHP SATA HDD cage; includes 4 LFF hard drive carriers
  • PCI-Express Slots 1 standard (1-Low Profile) PCIe 2.0
  • Power Supply 150W Non-Hot Plug, Non-Redundant Power Supply

Another nice features are a MicroSD slot on the motherboard – I’m still unsure if this can actually be used as a boot drive or not. Even if that’s not the case, next to the MicroSD slot is a USB port that you can plug a USB drive into for booting, seperate to your disks in RAID.  Then there’s HP Intelligent Provisioning which lets you stream your Firmware updates and  kick off OS installs, adding required drivers as part of the process hp.com – there’s a lot of other nice menu driven options in the Intelligent Provisioning system too (accessed by pressing F10 at startup) including diagnostic checks and modifying system settings.

One of the Operating Systems that this unit is designed to work well with, is Microsoft Windows Server 2012 Essentials. For up to 25 users, there’s no other client access licenses required, but it must be the Active Directory Domain Controller. Officially supported Operating Systems are:

Microsoft Windows Server
Red Hat Enterprise Linux (RHEL)
SUSE Linux Enterprise Server (SLES)

As an aside, I was speaking to a colleague about the new MicroServer as he is running two of the older models at home – overall he was very impressed between the two models and the extra features this one has – but it does come with a bigger price tag. It’s much more of a proper business server than a business class desktop.

There’s a lot to cover about this kit, so in another post I’ll delve deeper into items like RAID and the optional HP PS1810-8G Gigabit switch which fits snugly below or on top the HP MicroServer hp.com. If you have any questions or anything you’d like tested, please comment below and I’ll do my best to include that in the next post. I’ll also be looking at how I’ve chosen to set it up for myself, including getting the Firmware updates working via Intelligent Provisioning, which I think is failing due to my slow 512k upload speed, being shared with other things going on.

Oh, I almost forgot to mention – you can have your HP ProLiant MicroServer Gen8 match your mood! Changeable front plates can match your outfit if required :)


I’m rather impressed with this server – it would be even better if it had RAID 5 on board, but it’s designed really well for ease of access. Some online discussions I found have been around noise concerns, but I found the unit I have to be rather quiet.
