The Prestige Continues - Community Edition

My previous blog post titled “Nutanix Community Edition. The Prestige” – I discussed the concept of taking something “Ordinary” and making it “Extraordinary” followed by the grand “Prestige.”

Take the recent platform updates contained in our Acropolis Base/Hypervisor/Storage Fabric and combine that with the latest generation of Intel’s NUC (Next Unit of Computing) family and our Prestige continues to evolve with Nutanix Community Edition (CE).

In version 4.6 we introduced a wealth of feature sets and advancements including;

► Updates to the Distributed Storage Fabric; Scale-Out file server, Volume Groups, Self Service restore, etc..

► App Mobility / Cross Hypervisor DR

► OpenStack Integration and much more …(More information here)

While the platform continues to deliver exceptional features, and greater value, the main constraint we were faced with was the limitations of Intel NUC 5th Generation hardware. An Intel i7 Processor (2 cores @ 3.1Ghz) and up to 16GB RAM (Supported), required a “tweak” to CE’s installer to ensure it would pass its hardware validation tests since the NUC would not meet the 4 Core Processor requirement to operate the Controller Virtual Machine (CVM).

[ Related: Nutanix Community Edition. The Prestige ]

For the average home user/developer/partner, this was not a big deal. Neither was Overcommitting on CPU and yea you could lower the CVM’s RAM requirements to squeeze in some more VM’s – But you’re now in unsupported territory.

Picture1.pngThanks to Intel’s 6th Generation NUC, the Skull Canyon - we are no longer faced with these limiting constraints since this tiny form factor PC (211mm x 116mm x 28mm) delivers an incredible amount of horsepower and platform capabilities in your pocket!

With an Intel 6th Generation Processor (i7 / 4 Cores @ 2.6Ghz), up to 32GB RAM and Dual M.2 Slots for SSD’s, you now have the ability to take advantage of feature sets like a Scale-Out file server, Openstack or simply just build better demonstration capabilities for your customers and prospects.

Perhaps you just want to build a home lab or develop a cluster in a box solution similar to my previous blog. The possibilities are endless.

So first things first, what do you get with the Skull Canyon kit? Inside the neat packaging, you’ll find;

Picture2.pngThe Skull Canyon NUC

► A Spare cover (without the Skull logo – I must admit, I’m not a fan of the pirate like theme)

► A power supply 19v/120w (USA Specific adaptor only) – The wattage is higher on these, infact double, but I suppose that has to do with the horsepower + the 3D graphics etc

► Vesa mounting bracket

► Instructions….And not forgetting the little intel sticker

Note; you will need to provide your own RAM as well as your SSD’s since the Skull Canyon does not come with these components.

For this build we are using Kingston Technology Hyper X Impact 32GB Kit (2400MHz DDR4) as well as FIPS-140-2 Certified and validated SSD’s from Integral.

Picture3.pngHaving the SSD’s encrypted means that our data is safe and secured with AES 256Bit Encryption – Even to the point where the chip’s on the circuit board feature a tamper proof epoxy resin that will disintegrate the chips if you were to try and de-solder if from the circuit board. Pretty neat huh?

After the hardware components were installed (RAM and SSD) – It was time to install Community Edition.

To get started you’ll need to first register and download the latest build/image file of CE, as well as spare/blank USB key to create the bootable image of AHV.

If you’re a Nutanix User already, the bootable USB Device is like the SATADOM inside a conventional rackmount server.

This will live permanently attached to the NUC.

► Once you’ve downloaded the bootable image file, the next step is to create a bootable USB Flash drive from the CE image

► On a Mac:

► Insert your flash drive

► In a terminal window run “diskutil list” to determine the device node assigned to your flash media (e.g. /dev/disk2).

► Next run “diskutil unmountDisk /dev/diskN” (replace N with the disk number from the last command)

► Now type “sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m”

 

  • Note: /path/to/downloaded.img is the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).
  • /dev/rdiskN is the location of the USB Flash drive as you recorded in step 3b

 

► On a Windows PC

► Download a utility called Rufus to create the USB Bootable drive from the CE Image file

► It’s pretty straight forward, though make sure you set “Create a bootable disk using dd image.”

  • Browse to the location to where the image file is located and click the start button to begin the process

Now since the Skull Canyon is pretty new, you’ll find that the drivers for Intel NIC aren’t included in the AHV build (Don’t worry we’re working on this…) So, for now, we’ll need to install the drivers manually.

 

Thanks to my colleague Adam Fried-Gintis (Community Edition Lead) for providing the necessary steps!

 

  • Insert your newly created USB key into either a Windows PC with a utility like EXT2FSD installed so you can read/write to the EXT4 based partition on the USB key or a linux based VM.Download the file “e1000e.ko” file and copy/overwrite the existing “e1000e.ko” driver on bootable CE USB stick into the following directory:
  • Download the file “e1000e.ko” file and copy/overwrite the existing “e1000e.ko” driver on bootable CE USB stick into the following directory:
    /lib/module/3.10.0-229.4.2.e17.nutanix.20150513.x86_64/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko
  • Once copied/overwritten – Insert the USB key into your Intel NUC and proceed to boot off the USB Key
  • You’ll now see the following prompt:
Picture6.png

 

  • Login as “root” and the default password “nutanix/4u”
  • Load the Intel e1000e driver by typing:
    modprobe e1000e
  • Restart the network service by typing:
    service network restartLog out of “root” and now run the CE installer
  • Log out of “root” and now run the CE installer
  • Type “Install” to get started
Picture7.png

 

  • Enter the relevant IP addresses for your CVM and Hypervisor
  • Select “Create Single-Node Cluster” if you only have one appliance
  • Accept the EULA and Select “Start.”
  • Once the installer concludes, simply enter the IP address of the Controller Virtual Machine (CVM) in a web browser, and you’ll be presented with Prism.
  • While you’re at it, make sure you check for updates too.

Now that the cluster was installed and fully functional, it was time for some Plasti-Dip and Nutanix branding of course.

 

Plasti-Dip is such a versatile product with multiple use cases. Think of it as vinyl wrapping though you’re spraying it out of a Can!

 

The best part about this product is that you can peel it off when no longer required.

Simply spray 5-6 even coats and let it dry and you’re done. Easy!

Great to hear @gene_torres and if you write a blog post I would be happen to post it on the community blog Smiley Happy 

 

Have fun!

Great- now if only I could get my i5 NUCs to work since I bought them right before Skull Canyon came out!  GRR!

I haven't had much more time to fight with it, but on the i5 NUC with a NVMe drive it still seems to tell me that the drives aren't fast enough. I tried tweaking the checks but still no joy.

 

I was, however, using a more up to date build than you had originally referenced I think- do you think I need to do the e1000 to load this build on the i5s as well?

Explorer

Great articles you've done on the NUC's.  I am about to refresh my home lab from HP MicroServers and replace them hopefully with Skull Canyons.  Any chance that CE will utilize a USB 3/Thunderbolt Gigabit adapter for extra networking.  I've seen articles for ESXi working with the Startech USB 3 to Gigabit adapter.  Thanks!

Explorer

I feel the urge to get a home lab again. These look absolutely gorgeous.

Voyager

Great article! Seems that I will spend some $$$ (resp. CHF) after .NEXT to build my personal Lab with sugested Hardware!

Community Manager

Hope you all are able to come to .NEXT this year- be great to meet you in person and also introduce you to @richardarsenian - He also has an unconference session that will go into building the NUCs.

Hopefully at Vienna .NEXT event @aluciani !

Voyager

@aluciani  

@richardarsenian

That would be great...just let me know when & where!

I'll be in Vegas this for .NEXT in a few weeks, so I'll be definitely looking out for the session @aluciani . Hope to meet you too!

This is sweet!

Are you using no HDD in this setup? 2 SSDs or just one?

Wayfarer

Is anyone else having trouble with the e1000 zip file?

I keep getting messages that it's an invalid archive...

Explorer

I'm also having trouble with the e1000e zip file.

 

On Windows using 7-Zip

I can open the file "e1000e.ko 2.zip", however the file inside e1000e.ko.zip cannot be opened.

 

On OS X using Archive Utility

A file e1000e.ko-2.zip.cpgz is created after downloading and opening "e1000e.ko 2.zip".

 

What have I missed?

 

Edit: As it turns out, renaming the downloaded file from "e1000e.ko 2.zip" to e1000e.ko and putting it on the USB stick (and not trying to unzip it) works perfectly.

Thanks for the feedback @Bluescreen @DJEshelman

 

I'll look into it

Voyager

I have pretty much the same setup with the skull Nuc. I cant get past the Minimum requirementsError: A set of disks matching the minimum requirements was not found. I have 480 SSD and 4 TB plugged in usb3 port. Still no go. Any suggestions

Wayfarer

I'm not positive but I think the installer won't accept USB storage as an option. You'd probably want to use an internal spinning drive anyway in most cases.

Voyager

This model of the NUC doesn't have the internal 2.5 HDD slots like some of the others. So the USB was a shot in the dark. Even with out the USB Drive I still get the disk not matching. Any way to bypass?

 

Voyager

Having 2 SSD's pass the check?

Wayfarer

I don't have it in front of me but the last time I had an issue with the drive not passing I commented out some lines in the disk check script :-)
Then again, I'm still on NUC5's - I haven't splurged on the Skull Canyon yet :-)

Voyager

Can you share you changes to the script?
