EXCLUSIVE: The Microserver Switch Module revealed

After the “Top Secret” photos earlier in the week, we can now reveal the following Microserver Module – a PS1810-8G Gigabit Ethernet switch. Basically it is the normal HP 1810-8G switch (Product code J9449A) stuffed into a new Microserver-shaped case.

Looks pretty good, and the specifications of the 1810-8G are really good. 802.3ad Link Aggregation, Vlans, all the really handy stuff you want as a network admin. I think this will be a game changer in the small branch offices.

Why? Because it will make it easy to run a couple of Microservers, team the Network cards on each into the switch, and uplink them into the workgroup switch. It also leverages Power over Ethernet (PoE) to power the switch on port 1. If you have a larger workgroup switch that already has PoE capability which is often used to provide 48VDC to devices via the ethernet cable in order to power them without plugpacks, you can use that to power the switch and reduce cabling clutter.

PoE is mature technology and is used to power devices like IP Phones and WiFi Access Points. I am seeing more and more affordable PoE switches in the enterprise as IP Phones are making their mark and business sees the benefit of not having powerpacks everywhere.

As you can see the module is shaped to the design of the Microserver and is stackable. Very neat and tidy.

And finally here is the HP Sheet on these. Click to enlarge it!

I hope you can all see where this is going. After my previous post regarding the External Storage Module being dropped, then being told that a backup module exists, it starts becoming pretty clear that the Microserver range will be used as a base to external modules. I think it is a really cool system, keeping the base unit small and cheap to manufacture, while giving customers the opportunity to expand their systems as required.

EXCLUSIVE: Internal photos of the HP Microserver G8 leaked

Well here are the photos you have all been waiting for – a world exclusive of the HP Microserver G8 with all the internal photos to answer all the questions you were after,  and a full 7 days before the Official HP product announcement.

 

HP_Microserver_G8_Int_Front

First off, we have inside the door. We see a completely different design in the G8 from the outgoing G7. The biggest changes are the stock HP Non-Hot Plug LFF Drive caddies, some of you may already be familiar with these from the DL120 servers. Also the front of the server is closed with meshed steel panelling. This is quite the change from the open fronted G7 where you could open the door to gain access to not only the hard disks in the cage, but also the internal USB port.

Other features of note include a magnetically latched door, and no apparent locking mechanism. To me, this seems like a major oversight from HP as they are positioning this model as an enterprise-ready, remote branch office basic file & print server, maybe doing local Active Directory, DHCP & DNS. As a IT Consultant that specialises in hardware and networking myself, I know how inquisitive fingers can be. If I was putting any sort of server in a remote location, I would want it locked down tight. The key lock of the G7 achieves this, but is conspicuously absent in the G8.

And yes, that thing on top we cannot tell you about yet, but there will be a reveal on this blog later this week ahead of the official HP announcement of this server at HP Discover in Las Vegas on 11-13 June.

HP_Microserver_G8_Int_FBWC

Next we pop the case off and have a look on top. We see a large rubber grommet on the top of the Microserver unit, stamped with ‘FBWC’ – or in HP jargon – Flash backed Write Cache. This is what will turn your standard disinterested RAID10-level B120i controller into a much more efficient and effective RAID5 unit.

You can look up the cost of these FBWC modules yourself, but brace yourself for some sticker shock as they are not cheap. Also, we have not yet spotted a header on the motherboard where these plug in.

On the right you can also see the quick-release tab for the slimline DVD/RW optical drive. You have seen these on most of the current G8 servers and probably some of the bigger G7’s also.

HP_Microserver_G8_Ext_Rear

We now move to the rear of the unit, where we can see two Gigabit Ethernet ports, four USB3.0 ports as previously confirmed on this blog, VGA port, dedicated iLO4 port, and a low-profile PCIe x16 slot. There’s also a standard IEC power plug for the PSU, and you will notice the sound-deadening rubber grommets around the main fan screws which help to lower noise.

One thing that may slip you attention – the quick release motherboard tray tab just underneath the main fan. Push that tab down, and as long as you have unplugged all cables in the motherboard then you can pull that entire motherboard tray out bacwards without tools. For those of us with skinned knuckles after the G7, this looks extremely easy to work on.

HP_Microserver_G8_Int_RightHandSide

We now look at the right hand side, and there are two major points of interest. First and most obvious is the two memory slots which will make memory replacement one of the easiest things you have ever done, definitely easier than upgrading the RAM in a laptop. Bravo HP, you are to be congratulated on this very intelligent design.

So what is the second thing I hear you ask? That blue tab halfway up – that’s your new door locking mechanism! Close the door, push down on the blue tab and it will lock the door shut. Still not the best or most secure solution in my eyes, but will keep most inquisitive fingers at bay.

HP_Microserver_G8_Int_LeftHandSide

Now, the side you all really want to see. A standard 150W power supply could indeed be replaced by a more efficient PicoPSU supply and leave plenty of room for at least a couple more drives, maybe you could squeeze 4 2.5″ drives or SSD’s in there.

There are plenty of other goodies in here, but we need to take a closer look.

HP_Microserver_G8_Int_LeftHandSideDetail

BOOYAH! Click on it to take a closer look!

There is plenty going on here, so lets take it one step at a time.

First off is the CPU. Now that looks like a reasonably standard Northbridge heatsink, but in this case it actually does the cooling duties for an i3-3220T CPU. This CPU has a TDP of 35W and is pretty much the limit for non-active cooling with a fan. We cannot see if there is a socket under there, but the heatsink seems to be fairly high off the motherboard so initial signs look good for a socket.

Moving left, we can see the power MOSFETs for the CPU power have a heatsink on them too. This will be helpful and make the G8 more reliable.

Further left again and we can see the HP iLO chip which houses plenty of internal smarts for out-of-band remote management. In my day job, we only use HP servers and iLO is the best remote management solution out there bar none. If you haven’t experienced iLO in an enterprise server yet, then you are in for a big surprise.

Towards the front we have the single PCIe x16 expansion slot. This is a little disappointing as many of us were using the x1 slot on the G7 for another network card, possibly a TV tuner. Personally I modded the x1 and proprietary x4 slot into open slots, and dropped a HP NC360T dual-port Gigabit Ethernet card into it. that addition gave me a total of 3 network ports which is almost a requirement for an ESXi lab machine. Hopefully I can get a USB3.0 network adapter which is on the VMware Hardware compatibility list soon.

Down the very front you can spot a MICRO SD CARD SLOT! SD card slots have been on the motherboards of a number of HP servers for a while now, but I have never seen a Micro SD card slot. This is an amazing addition to the Microservers. Next to it you can see the USB2 port for booting from a USB stick – handy for BIOS flashes, or even booting ESXi or FreeNAS from instead.

To the far right we can see a single SATA3 6.0Gbps port, whereas we had documentation leaked from HP stating two SATA3 ports on the motherboard. Now we hope the final units have two ports but I can imagine HP seeing it as a non-essential port. You have got one SATA port for the DVD drive, why do you need two? It seems like HP does not want us to have extra drives.

Finally, we can see the SAS connector on the furthermost right, again providing onboard hardware RAID to the drives in the internal LFF cage.

HP_Microserver_G8_BetaUnitSpecs

Finally, the specs of the beta machine. Please remember that this is a beta unit and specifications usually do change. That said, this unit looks reasonable close to manufacturing ready and I doubt there would be too many changes to the chassis or motherboard. About the only thing to change would be the CPU I would suggest.

I hope you have enjoyed our run-through of the beta G8 model, and stay tuned for a special top-secret reveal later this week. I would suggest subscribing to our RSS feed so you get the information as soon as we post it.

It’s not a Microserver, it’s a Micro-Ecosystem for IT

The beta program for the upcoming HP Microserver G8 is in full swing. At least two beta units are out in the field within my sphere of contacts, however I refused the offer to take part in any beta after the removal by the HP Microsevers page on Facebook.

Some of the details I have been leaked by internal HP contacts is only now becoming clear. I was given the follow images last week from someone inside HP.

Microserver_G8_Side Microserver_G8_Stacked

These show a very modular unit, indeed stackable with other Microserver-like chassis units. This feature was considered to be a part of the external storage unit, however with that also confirmed as no longer happening, the modular design seemed to have been a hangover of the previous product development and design.

That is until today. A source familiar with the beta program has passed on the information of a

“stackable unit, smaller in height than the Microserver unit itself, for backup purposes”.

This highly curious information could mean any of the following devices could be on the way:

  • A single high capacity hard disk of 3TB or 4TB;
  • An RDX unit that uses a hard drive in a removable cartridge format; or
  • An LTO4/5 tape backup unit.

Considering the four USB ports on the back, all quite possible scenarios. Of these, I think the RDX unit most likely as this unit is being targeted at the smaller remote offices where a simple backup solution is often lacking.

Another beta tester has raised the possibility of another component that they have actually received and are testing. While I cannot divulge this information yet as it may be traceable back to the end user due to forums I frequent. That said, I was surprised that this sort of module is available and currently testing with customers, but is a brilliant move by HP.

Finally, we found this on a slide from an internal HP source… I wonder what this could be?
