My most popular post on rsts11 has been my compact VMware server at home post. Thanks to Chris Wahl mentioning me on the VMware forums, and linking from his lab post, I see a dozen visits or more a day to that page.

Imitation is the sincerest form of laziness^wflattery

I have to admit that I’ve been a follower in my use of intriguing lab environments. I got the vTARDIS idea from Simon Gallagher, and built a version of it at work at my last job on a Dell Core 2 Quad workstation under my desk. Then I saw Kendrick Coleman tweet about this new SH67H3 from Shuttle that supported 32GB of non-registered RAM… bought one and put 32GB and an i7-2600S processor into it, as mentioned in the “server at home” post mentioned above.

Now as you may know, the i7-2600 series processors are now a generation behind. Sandy Bridge gave way to Ivy Bridge (the i7-3×00 processors) which are currently easily found at retail. But… SH67H3 v1.0 motherboards don’t support Ivy Bridge. And that’s what was shipping when I bought mine in early 2012.

I found an unbelievable deal on a second SH67H3 open (missing) box at Fry’s in February 2013… let’s just say I spent more on a basic Pentium chip to test it with than I did on the chassis itself. But alas, the second one also had a v1.0 motherboard.

Let’s make the ivy (bridge) grow!

I found sources on the Internets that said a v2.0 board supporting Ivy Bridge was out. I further discovered that Shuttle would trade in your v1.0 board for a v2.0 board for $40. Instructions here at Cinlor Tech’s blog if you’re interested in doing this yourself. Note that you can request the case number through Shuttle’s web-email portal if you prefer this to calling. That’s what I did.

sh67 corpsesI shipped off my two boards in a medium Priority Mail box to Shuttle on the 26th. On the 29th I got confirmation of the return shipment. They should be at my door on April 2nd. I’ll be reinstalling them, and at some point upgrading to the i7-3770s processors on both.

Waitasec, 2600 “S”? 3770 “S”? What’s this all about, then?

Yes, that’s correct. I chose to go with a low power version of the i7-2600 processor a year and change ago. The i7-2600s has a lower base speed than the 2600 or 2600k (unlocked version), 2.8ghz vs 3.4ghz. All three support turbo boost to 3.8ghz though. And the i7-2600s is 65W where the others are 95W.

(Here’s a comparison chart of the three i7-2600 and three i7-3770 processor options via Intel, if you’re curious.)

Other noteworthy differences are on the 2600k, which costs $20 more, but does not support VT-d (directed I/O), vPro management features, or Trusted Execution. VT-d is the only feature of particular concern when you’re building your virtualization lab though. (I’ll admit the VT-d was an accidental discovery–I chose the 2600s more for power savings than anything else). If you’re building a desktop, the “K” model has HD3000 graphics vs HD2000 for the other two chips, by the way.

Now that I’m building a second box, I find that my usual local retail sources don’t have the i7-2600s in stock anymore. I could order one on eBay or maybe find it at Fry’s, but for about the same price I could get the Ivy Bridge version and be slightly future-proofed. Once again, the “S” is the way to go.

The 3770 series run at 3.1ghz (“S”), 3.4ghz (3770), and 3.5ghz (“K”) base speeds, all turbo capable to 3.9ghz. The “S” processor is 65W again, vs only 77W for the other two chips. They all have Intel’s HD4000 integrated graphics and the newer PCIe 3.0 support. They support 1600mhz RAM speeds, vs 1333 top for the previous generation. The “K” processor lacks VT-d, vPro, and Trusted Execution, but does have a nearly $40 premium over the other two chips.

All six of these chips have VT-x including extended page tables (EPT/SLAT), hyperthreading, and enhanced SpeedStep. And they’re all 4 core/8 thread/32gb RAM capable processors that make a great basis for a virtualization environment.

nuc-scaleSo what’s next, Robert?

Well, with two matching machines, I’ll be basically starting from scratch. Time to upgrade the N40L Microserver NAS box to 16GB (Thanks Chris for finding this too!) and probably splitting off a distinct physical storage network for that purpose.

But now, thanks to Marco Broeken’s recent lab rebuild, I’ve been introduced to Intel’s Next Unit of Computing (NUC), so tune in soon for my experience with my first NUC system. Sneak peek of the ESXi splash screen and the actual unit here… stay tuned!

rsts11: Building my compact VMware server at home

Posted on by

About a year ago I bought a homebuilt Intel Core i7 (1st generation) desktop from a friend to run VMware ESXi on. He had gone to the trouble of assembling the system with a beautiful Gigabyte motherboard, and getting 4.1 to run on it, and I got a good deal on the system with 6GB of RAM and a 2TB hard drive.

I upgraded to 12GB, then to 24GB, but never put it into use.

Two months ago, I started it up and ran some computationally intensive software on it and discovered it was munching 320W. And it’s a mid-tower size case. Somewhat unwieldy for an apartment with a few other computers already running, and a significant other who doesn’t appreciate a living room that resembles a small colo.

It gets… smaller…

About that time, I think it was Kendrick Coleman who mentioned a new Shuttle barebones XPC system, the SH67H3, that in typical XPC form factor supported a second generation i7 processor and 32GB of RAM. Four slots of DDR3. Problem was threefold.

1) Shuttle on the VMware HCL? Unlikely.

1a) Onboard LAN and SATA controllers supported? Almost as unlikely.

2) 8GB DIMMs were expensive. And how could I in clear conscience run a system capable of 32GB with just 16GB of RAM?

3) Have you seen my holiday credit card bill?

So I was willing to risk 1a, live with 1 (as I’m not buying support or expecting it), and wait out 2 until memory prices came down.

Once 3 was resolved, I emptied my wallet into the cash register at Central Computers and bought the SH67H3 barebones XPC, and an i7-2600s (low power) processor. I had a pair of 2GB DDR3 DIMMs to use until I could upgrade, so I went about installing. I hung a SATA DVD drive off the system and installed ESXi 5 to the flash drive, and all went well.

Well, not quite.

Turned out one of the two DIMMs was bad, keeping the Shuttle from taking off, so to speak. Brief monitor sync and then it went out of sync, no beeps, no signs. I tried one DIMM, it worked; tried the other, it didn’t. Swapping the DIMM slots didn’t help. So I booted with one DIMM, 2GB, the minimum to run the ESXi installer.

No dice.

Turns out system reserved memory and/or shared video RAM managed to pull me under 2GB, and the installer quit on me.

So I realized I had 6 4GB DIMMs in the old VMware box, and I pulled two to get the Shuttle system going. Bueno. Just short of 10GB and it installed pretty well. The Shuttle disk and network were supported under ESXI 5.0.0 without any additional effort.

It got… better…

By the time this happened, I found some 8GB DDR3 DIMMs on Amazon from Komputerbay. These were not on the Shuttle compatibility list, but they were less than half the price, so I took a fortuitous risk. I’ve bought memory from them before, for the last ESXi server I built (at my last job), so I was willing to try out a pair. The memory was $58/stick, and I paid $10 for expedited shipping (twice, as I bought two pairs separately just in case).  They worked fine, survived memtest86+, and made me happy.

I added a 4GB Onyx flash drive from Maxell, a very low profile drive that hides on the back of the system, to install the hypervisor onto. (Picture shows it in an extension USB pod, to show how much it sticks out. It actually fits in a regular soda bottle cap.)

For disk storage, I put a four-drive SATA enclosure in the 5.25″ half-height bay, and occupied the two SATA3 and the two SATA2 ports on the motherboard. The first bay got a 50GB SATA2 SSD I had on hand, for the initial datastore, and the second has a 500GB 7200RPM SATA disk.

I’m almost embarrassed to admit that the first VM I built on this system was Windows 7 Professional, but it was. And it worked pretty well.

Then the little one spilled a handful of change behind an electric plug and blew up the circuit breaker, while I was away from home… so it’s been on hold for a little while.

What’s in the box?

I bought the following new:

  • Shuttle SH67H3 barebones ($240 at Amazon)
  • Intel Core i7-2600S processor, retail box ($300)
  • 4x Komputerbay 8GB DDR3 RAM ($53 per stick, $212 total)
  • Four-drive 2.5″ SATA cage ($71)
  • Intel PCIe x1 Gigabit Ethernet adapter ($40)

The following came from stock.

  • 4GB Maxell Onyx flash drive ($9)
  • 50GB OCZ Vertex 2 SSD ($126, much more when I bought it)
  • 500GB 7200RPM SATA drive ($120 today, much less when I bought it)

So to build the whole mess today, I’d pay about $1,118 plus tax and sometimes shipping.

What’s next, Rob?

Well, I’m going to be a bit limited by 4 2.5″ drive bays, although I will probably put some more drives in there. I have some 32GB SSDs that are gathering dust, and a couple of 500GB disks, so we’ll see how that goes. The Patriot Pyro SSDs are coming down in price (after rebate) at the local Fry’s store, so maybe I’ll make use of the SATA3 channels.

But for now, my next step is going to be a home NAS (that I threatened to do a while back) starting from an HP N40L Microserver. The Microserver, and its 8GB of DDR3 ECC RAM, came in last month. FreeNAS 8 is currently running on this system,  with an internal USB flash drive, although I’m tempted by OpenFiler’s ability to serve as a fibre channel target.

I will probably put the 8GB of RAM back into the mid-tower VMware box and use it as a second node, put some multiport cards into both ESXi servers, and power up a Summit 400-48T switch for the backbone of my virtualization network. I’m still watching for absurdly affordable PCIe 10GB Ethernet cards (since my Summit 400 has two 10GBE ports), but all I have for now is PCI-X, and only one of the three involved machines has even PCI.

I also now have a second location for lab equipment, as you may see in my write-up of the new store I’m starting. So the old desktop, and probably a Fibre Channel-enabled OpenFiler on a small SAN, will go over there. I can replicate across a 20ms latency link once, and have a pretty valid test environment for anything I’m likely to do.

Random thoughts

The LAN (RTL 8111E Gigabit Ethernet), and SATA onboard on the SH67H3 were supported out of the box, no oem.tgz tweaking needed. I had an Apricorn PCIe SSD/SATA3 controller that I plugged in with the SSD, but it wasn’t recognized by ESXi, so I went forward with the drive bay options.

I haven’t tried the SATA RAID on this system. I wouldn’t expect it to be supported, and I’d be inclined to use FreeNAS or OpenFiler or NexentaStor Community Edition to handle resilience, rather than the onboard RAID. If I get a chance, I’ll configure a pair of disks under the onboard RAID just to see how it works, or if it works. But it’s not a long-term prospect for this project.

Other people doing similar stuff

My friend Chris Wahl just put together his home whitebox systems. He went a bit more serverward, and he’s going with a pre-constructed NAS from Synology (which was tempting for me).

Kendrick Coleman wrote about his “Green Machines” project for his lab, and has built out a bit more (and put a bit more detail into his shipping list).

Simon Gallagher of vinf.net fame is well known in Europe for his vTARDIS projects, virtualizing virtualization inside virtual machines. Or as Nyssa said in Castrovalva, it’s when procedures fold back on themselves. I was reading about this, and doing a little bit of it on a quad core desktop at my last job, so I think he gets credit for my thinking about this scale of virtualzation in the first place.
