HP Proliant Microserver review

I’ve been looking for a while for a machine that can run a RAID array, giving me somewhere to put my media and backups that wont lose everything if a hard disk dies. My real problem when looking for something that fits my needs is price. There’s plenty of capable devices out there, but they tend to get expensive quickly – a Drobo or multi-disk NAS box can set you back £300 before you’ve bought any disks.

HP have a product that fits the bill in both features and price – the Proliant Microserver. The unit retails at £199 + VAT, and HP have been running some amazing cashback schemes netting you the box for about £140 all in.

Microserver on a desk
The form factor is similar to that of a shuttle case, but not as deep. It sits quite nicely on a desk, and is small enough to hide away anywhere with decent ventilation.

Microserver front panel
The front of the Microserver has 4 USB ports, the power button, and two indicator lights – 1 for disk activity and one for network activity. The power button glows orange when in standby and green when powered on. Additionally there’s a nice blue light that illuminates the HP logo when the machine’s on.

Microserver back panel
Things are kept simple round the back, with a couple of extra USB ports, the Gigabit Ethernet interface and an e-SATA interface. There’ also a VGA port for connecting a monitor during installation. It’s worth noting the lack of PS/2 interfaces – you’ll need a USB keyboard (or at least an adapter) for installation.

Microserver with front panel open
Opening up the Microserver is simple. The keys provided open the lock on the right of the front panel, which swings open like a door to reveal the innards. Here you have the 4 hard drive bays, with the power supply tucked away on the left, and the motherboard underneath.

Microserver Motherboard
The motherboard is easily accessibile by removing a couple of torx screws (using the supplied torx wrench) and unplugging a few cables, after which is slides out. Notable features here include an internal USB port (could be used to add WiFi, or even USB storage for the OS) and the passive heat sink on the processor at the back. All cooling is provided by the large fan at the back of the case – luckily this is big enough to be able to run reasonably quietly while still providing adequate cooling.
There’s 2 RAM slots available – the model I bought came with a single 1GB stick, but up to 8GB is supported. There’s also a couple of half-height PCI-e slots which can be used to expand the server’s functionality.

Microserver hard drive bays
There’s room in the server for 4 hard drives. Each needs to be screwed into one of the supplied mounts, after which is can be easily slotted in to the mounted SATA connectors – no faffing around with cables! The disks dont connect to a RAID controller, although Fake RAID is supported by the motherboard. However, I’ve been advised it’s safer to rely on software RAID in this case. My server was supplied with a 250GB drive – I’ve added 2 1TB drives in a RAID 1 (mirroring) configuration. There’s room for an optical drive in the bay above the hard drives, but this can also be converted to fit an extra hard drive. Of course, if that’s still not enough for you, the e-SATA port and PCI-e slots leave room for even more storage to be added on.

Installing the server was straightforward – I created a bootable USB drive and popped it in the front, then told the server to boot it (it defaults to PXE boot when there’s no OS installed). Once up and running, it’s nice and quiet thanks to the single large fan, although it does vibrate slightly. Placing the server on my wooden desk amplified this somewhat beyond acceptable levels, so I ended up sitting it on some of the plastic foam that came in the box (as shown in the first picture) which fixed the problem straight away. The 1GB of RAM is easily enough for my purposes (more on that in the next few posts), although the processor isn’t going to win you any races. You get a dual-core 1.3GHz Athlon, which spends a lot of its time dynamically throttled down to 0.8GHz. This can make some things (like installing updates) take longer than you might expect, but it does give the machine a big advantage – very low power consumption.

All in all, this server is one of those devices, like the O2 Joggler, that’s not amazing in itself but is great for the money you pay. At the time of writing, HP are still offering £100 cashback for up to 5 units, and we’re running a competition to win one in an upcoming episode of the Ubuntu UK Podcast.

I mentioned on the show that I’ve been using the server to replace some of the cloud services I use with self-hosted applications. My next few posts will talk about how I’ve done it!

    Hi Mark,

    It’s not obvious in the pic but can you use the bays for all data drives or does the OS drive take up one of the bays.

    I ask because on their older home storage things they had bays for space but the OS drive was separate, which I think is handy when dealing with a bunch of storage drives.

    The drive that comes with it takes up one of those bays. However, you do have a couple of options if you don’t want to use all 4 slots for data drives.

    Firstly, you can get a mounting kit to mount a 5th drive in the optical bay above, and use that for the OS.
    Secondly, you could put a reasonable sized USB stick in the internal USB port, and install the OS there. It might even be possible to fit a eeePC sized SSD into one of the PCI-e slots, I’ve not tried.

    Hello Mark. Congrats for the review. Have you tried ( or do you happen’ to know ) to install ESX on this server? Is is working? The hardware is compatible with ESX? Thanks

    I’ve not tried it myself, but Servers Plus sell a bundle with it preinstalled[1] so I can’t imagine you’d have any trouble with it.

    Hi Mark,
    Where would you get the fitting kit from? I assume it would come with a sata cable?
    I was wondering if you could use the 250Gb supplied for the OS in one of the bays but have two others used for data being mirrored?
    I have only just got the box and to test it out put the OS on the single 250Gb disk. But will I be able to configure the BIOS to use RAID (even if it means reinstalling the OS or do all disks have to be part of a RAID Logical drive?
    If the 5th drive used as you describe, I assume the four remaining slots can be used as RAID disks which seems to imply that the 5th disk can be on it’s own and not part of any RAID logical disk.

    Hi AJ,

    I don’t know exactly where to get them but it’ll just be a standard kit for mounting a hard drive in an optical bay, Google is probably your friend here. You might find them with SATA cables, or might have to buy them separately.

    I was wondering if you could use the 250Gb supplied for the OS in one of the bays but have two others used for data being mirrored?

    Yes, that’s exactly what I do.

    I have only just got the box and to test it out put the OS on the single 250Gb disk. But will I be able to configure the BIOS to use RAID (even if it means reinstalling the OS or do all disks have to be part of a RAID Logical drive?

    Because there’s no RAID controller, you can do what you like with the drives. I was advised against configuring RAID in the BIOS (I couldn’t get it to work anyway) so just set up software RAID on the two 1TB drives after installing the OS on the 250MB one.
