    As an avid fan of dedicated boxes, I have always opted not to use virtual machines in my production environment. Not because I am against it but rather for simplicity and backup. I have been playing around with Hyper-V as well as desktop VM solutions such as Virtual Box and VM Player for quite some time but found too many inherent limitations. On BYOB #70 we had an opportunity to discuss VMs with Paul Braren and talked awhile about ESXi hypervisor. At first glance it looks very complicated and somewhat intimidating. But after listening to Paul I wanted to give it a shot as I was anxious to try something that would provide features I needed to actually put into my production environment and use it.

     

    Problem and limitations of other solutions

     

    First off let me say that all solutions have their strengths and weaknesses. Desktop solutions are great for testing but rely on the desktop OS for stability. Hyper-V is very simple to use, powerful, but very limited in certain areas such as USB devices and for the most part, playback and video applications do not work correctly unless you add a dedicated video card. To better understand these limitations is important to define what I was trying to do. Here is a list of tasks I wanted to put on different machines and what I need them to do.

     

    IMG_0202

    • Monitoring software for viewing and recording 4 IP cameras. Must be able to playback content directly on the VM for review.
    • Install and run home automation software. VM must be able to access a USB controller.
    • Podcast/audio recorder. Must be able to access USB microphone, USB Web Cam and support sound playback.
    • Transcoding/Streaming. VM must be able to transcode Blu-Ray movies and stream them to my mobile device using Air Video and other similar utilities.

    As you can see from the scope of what I wanted to do (which are close to real world tasks many of us do) I needed my VMs to attach to specific hardware as well as have the ability to playback video. With Hyper-V, I was not able to do any of the tasks above and the use of desktop systems for production did not appeal to me as I want to maximize performance and stability.

     

    Phase 1

     

    After several discussions with Paul, I decided to give ESXi a try. I did this project in two phases. The first phase was testing using my Core I3 test system. I wanted to see what was involved as well as assess the performance of ESXi. After successfully installing ESXi, I was able to install the client OS and run all the applications above.

     

    Phase 2

     

    For the second phase, before I spent too much time configuring the client OSs, I decided to build a dedicated VM box that would ultimately take over the duties of at least two of my existing physical machines. Per Paul's information, I wanted a board that would support VT-d. Although I had no issues with the existing Gigabyte board in doing everything I wanted to do, I thought it would be best to plan for future expansion so I went on the search for a VT-d compliant board. Much to my surprise, I found the same results as Paul had found, and discovered that very few board MFG implemented VT-d. After looking around at various boards, I ended up with an AsRock Extreme 3 ($124). It was the cheapest compliant board I could find using the Z68 chipset and is directly supported by VMware. The processor and RAM was pretty straight forward and I ended up with a Core I5-2500 and 16 gigs of GSkill DDR3-1600.

     

    Final Configuration

     

    AsRock Extreme 3

    16 Gigs of GSkill Ripjaw X 1600 DDR3

    Intel Core I5-2500

    Lian-Li Lancool (existing case)

    Corsair USB 3 8 gig flash drive

    300 Gig Western Digital Raptor

    3T Western Digital green drive (Backup and temp storage)

     

    Power Consumption is 60-66 Watts at normal state.

    P1010871

     

    P1010889

     

    P1010878

     

    The process

     

    Based on Paul's recommendation and description of how this works, I used a USB flash drive to install the hypervisor on the machine. Set the boot order in the BIOS for CD, USB drive.

    Summary

     

    ESXi is the first virtualization package that I have tired that has the capability of doing all the tasks that I need to do in terms of controlling hardware. The installation process is easy and straight forward, however the client installs and configuration can be daunting at first. If you are patient and can get a bit of help, you will find that that "most" of the time it is a fairly simple process. The one thing I ran across that I thought was strange (though now it makes sense) was the installation of a separate driver pack in each of the client machines which optimized the mouse/keyboard, sound, and video. Prior to installing these drivers the mouse response was horrible and the interaction between the VM windows was frustrating.

     

    Conclusion - Did it all work?

     

    Well Yes and No. All of the tasks stated above were successfully loaded and setup into a VM and operated perfectly. The system ran great and was more than enough power to run all the VM’s I had setup (Total of 4). The main issue that I ran into that I am still trying to work out is despite disabling the power saving settings in the VM’s, the server seems to go into a sort of a reduced power state after a period of time. Normally this would be a desirable condition however because I am monitoring devices such as PhotoStream, Camera’s, USB home automation controllers, and Eye-Fi software this presents a problem as these items slowly stop responding. For example, after the server and VM’s sit for a while and I try upload some picture via my Eye-Fi there is no response. Alternatively, my home automation starts going squirrely and devices such as sensors stop working correctly. I am sure that since this happens to all the VM’s that there is a simple solution, however right now this is an issue. I have no doubt that I will find the problem but until then it will have to stay in the experimental state and I will have to continue to rely on a dedicated boxes.  I also ran into other minors issues which where not show stoppers I will mention it anyway.

    • Could not get the auto start/stop feature to work correctly.
    • Backing up the VM’s is straight forward but imaging the entire drive that contains the VM is a challenge.
    • Still Trying to figure out how to configure the UPS.  Easy to shut down one VM but shutting all the VM’s and the server is a different story.

    Next Steps

     

    I really believe that this is a viable solution once a few annoying kinks get worked out in my particular setup.  My plan is to continue working on this until I understand it better as the potential is too great.  It is still the best VM solution I have used and depending on your needs, and certainly your hardware could work and do everything you need it to do.  Once I figure all this out I will post an update.  Again a special thanks to Paul for the help and guidance he provided on this project and keep and eye out for Part 2…

    Mike, so glad you wrote this up! Doing some research on the going to sleep issue (something I've never experienced with my system), and also researching viable/affordable ESXi native backup options for home lab use (VMDK files on VMFS filesystem), ideally, more than just trialware. Meanwhile, I keep just using Windows Home Server to backup my VMs, which also de-dupes for me, affordably. I realize that's not as elegant as something like the native backup shown in the videos here: http://www.trilead.com/

    Wow, I'm surprised you were able to get it running using off-the-shelf retail components. ESXi has a pretty narrow list of hardware that it supports, and my impression is that you usually need to get name-brand pro stuff like a dell poweredge server or HP Proliant, etc.

    I did a lot of research before I built my ESXi 5.0 whitebox. Here are a few things that I found: Make sure that the components are listed as working with ESXi. The most up-to-date site that I found was here: http://www.vm-help.com/esx40i/esx40_whitebox_HCL.... (It says 4.0, but it is pretty comprehensive. The forums have more info.) A good primer on backing up is at: http://www.backupacademy.com/ It is created by the Veeam backup people. It does a good job covering VMware and Hyper-V.

    • I throw this out every once in a while.  Is anyone interested in writing up "semi-formal" reviews here on the forums?  I say semi-formal because they don't have to be pro level, just a good attempt at telling the story about the gear.  Something you have purchased lately.  You don't have to go buy stuff, just incorporate what you have already have purchased.  Hit me up with any questions.  You never know where it will lead!

    • OneDrive Personal Vault and expandable storage
      Microsoft's OneDrive has a few new features and options worth pointing out.  Personal Vault and Expandable Storage.
       
      Personal Vault is a protected area in OneDrive that can only be accessed with a strong authentication method or a second step of identity verification, such as your fingerprint, face, PIN, or a code sent to you via email or SMS. 
       
      Personal Vault gives you an added layer of protection for your most important files, photos, and videos—for example, copies of documents such as your passport, driver’s license, or insurance information—should someone gain access to your account or device.
      Plus, this added security won’t slow you down. You can quickly access your important documents, photos, and files with confidence wherever you are, on your PC, OneDrive.com, or your mobile device.

       
      Beyond a second layer of identity verification, Personal Vault also includes the following security measures:
       
      Scan and shoot—Using the OneDrive app, you can scan documents or shoot photos directly into your Personal Vault, keeping them off less secure areas of your device, like your camera roll.
      Automatic locking—No need to worry about whether you left your Personal Vault or your files open—both will close and lock automatically after a period of inactivity.
      BitLocker encryption—On Windows 10 PCs, OneDrive automatically syncs your Personal Vault files to a BitLocker-encrypted area of your local hard drive.
      Restricted sharing—To prevent accidental sharing, files in Personal Vault and shared items moved into Personal Vault cannot be shared.
       
      Taken together, these security measures help ensure that Personal Vault files are not stored unprotected on your PC, and your files have additional protection, even if your Windows 10 PC or mobile device is lost, stolen, or someone gains access to it or to your account.
       
      Expandable Storage
       
      If you are and Office 365 Subscriber you get 1 TB of OneDrive storage space with all the other Office goodies like Word, Excel, etc.  I know personally that I have gone over the 1TB limit and have always wanted to be able to add additional storage to my account.  Now you can!

       
      Pick and option and keep on hoarding, errr, I mean saving! Cancel anytime, upgrade at any moment.

    • Ubiquiti adds new items to the Unifi Line including UAP Flex HD and the Unifi Dream machine
      Ubiquiti has been busy.  There area ton of new items to recently released and I'm going to share two of my favorites.
       
      The UAP Flex HD and the Unifi Dream machine. The Flex HD is a mouthful of descriptors like most of UI gear is.  It's a 2Ghz 2x2 MIMO, 5GHz 4x4 MU-MIMO, POE, Indoor/Outdoor, multi mount, mesh point that is no bigger than a can of Coke.

       
      You will still need the Unifi controller although you can configure it with basic functionality with the Unifi App.  I've always found it's best to configure with your controller and then use the app as an add-on.  There are several mounting options that include sitting it on a shelf! That is something that Unifi has not had before unless you count the ceiling AP I have awkwardly mounted placed on top of a few books.  It can be found on the Unifi store for $179.
       
      https://store.ui.com/collections/wireless/products/unifi-flexhd
       
      The Dream Machine is an altogether different beast that I hope lives up to its naming.  This is the gateway drug, for lack of a better term, to the Unifi world.  The starter kit.  It is an Access Point, Gigabit Switch, Security Gateway, and the Cloud Key all in one package.  The latter being the most significant as this is something that has deterred new users from getting started with Unifi.  Requiring new users to purchase a $100 item just to run the AP's has been somewhat of a roadblock in the past.  Granted, that is improving every year with the ability to run it in the cloud, on a NAS, a Pi, Docker, MacOS, and of course Windows, it is still a barricade to getting up and running when manufacturers such as Eero offer simplicity in an app.
       

       
      The switch includes 4 LAN Ports and 1 WAN port.  All of which are Gigabit and security services such as IPS are rated at Gigabit speed. It's $299 in the Unifi store but I'm unsure how nicely it will play with other Unifi gear.  This may be a nice "first AP" with its built in Cloud Key if you can add additional units or other Unifi access points.
