    After listening to the many discussions and seeing several demonstrations about Windows Server 2012 Essentials (“S2012E”) at the 2nd Annual Home Server Show Meet-Up I decided it was time to get more serious by testing S2012E in a live environment with live data in a HP N40L ProLiant Microserver (“MicroServer”).

    HP N40L ProLiant MicroServer

     

    I began with the HP N40L ProLiant MicroServer with a Icy Dock DuoSwap MB971SP-B that I had originally described in The Icy Dock 5.25” Hot Swap Drive Caddy for a 2.5” and a 3.5” SATA Drive – DuoSwap MB971SP-B (“DuoSwap”).

     

     

     

    Parts List of MicroServer

     

    · HP N40L ProLiant MicroServer

     

    · 16GB RAM – G.Skill F3-1333C9D-16GAO – 16GB of RAM wasn’t necessary for this build with S2012E but this is what I had in the MicroServer that is my “play box. For a Production environment I would suggest looking at the Kingston 8GB KVR1333D3E9SK2/8G

     

    · WD PCIe USB 3.0 Card

     

    · Icy Dock DuoSwap MB971SP-B

     

    · 18” SATA Cable

     

    · eSATA to SATA Cable – Tripp Lite Model P952-18I 18” SATA to eSATA

     

    · Adaptor: StarTech 6” 4-Pin Molex to SATA 15-pin Power Cable

     

    · OS Drive: Crucial M4 128GB SSD

     

    · Data Drives: 5*ST3000DM001 – These drives were in various configurations but ultimately I’ve settled on the 5 drives in Storage Spaces 2-way mirror.

     

    · Backup Drive: STBV3000100

     

    · Host OS: Server 2012 Essentials

     

     

     

    Installation of the OS

     

    Because S2012E only occupied about 18.4GB of the OS drive I assumed it would be possible to install S2012E on a 60GB OS Drive as I had done with WHS-2011 in Installing Windows Home Server 2011 on a SSD in a HP MicroServer N40L. The effort failed and the install became stuck on the following screen:

     

    clip_image004

     

    Hitting restart just took me through a reboot and back to the screen above. No doubt there is a workaround but IMHO I think I'm better off just going with a SSD or spindle drive bigger than 90GB and not have to mess with it.

     

    I switched to a Crucial M4 128GB SSD for my OS drive for S2012E and the install went without a hitch.

     

    During all of my installs I would choose a Custom Install of S2012E and would remove all of the partitions from the target OS drive before selecting that drive for a clean installation of the S2012E OS.

     

    clip_image005

     

    Performance of the Crucial M4 128GB SSD that is my OS drive for S2012E. The Crucial M4 is a SATA III drive so the Read performance would be substantially higher if attached to a SATA III Port. All of the SATA Ports in the MicroServer are SATA II Ports which limits the top performance of SSD drives.

     

     

     

    Server Folder Warning

     

    I installed S2012E while only the Crucial SSD was in the MicroServer. This prompted a warning from S2012E that my server folders were on my OS drive – This is something I would have to address once I had decided on how to configure my Hard Drive storage.

     

    clip_image006

     

    I found that moving the Server folders is a very easy process via the Server DashBoard once I had decided where to move them.

     

     

     

    Two Mirrored Pairs set up in Computer Management

     

    My first idea was to configure two mirrored pairs (two RAID1 drive pairs). The first mirror pair would be for my critical data that would also be backed up to an external USB 3.0 drive while the 2nd mirror pair would hold less critical data. Both of these mirrored pairs were configured through Computer Management in the S2012E software.

     

    clip_image007clip_image008

     

    The 2nd Mirror is slower, as I expected, because I have one ST3000DM001 that is slower than all the others and by using that ST3000DM001 in this Mirror impacted the performance, as I expected. I considered Mirror2 to be the baseline for what I did next which was to break the Mirror and create a 2-way Storage Spaces with the 2 ST3000DM001’s.

     

     

     

    1 Mirror via Computer Management and 1 Mirror via Storage Spaces

     

    My next idea was to configure two mirrored pairs like before but this time the first mirror would be configured through Computer Management in the S2012E software while the 2nd mirror pair would be set up through Storage Spaces 2-way Mirror. The first mirror pair would again be for my critical data that would also be backed up to an external USB 3.0 drive while the 2nd mirror pair would hold less critical data.

     

    clip_image009

     

    The performance with the Storage Spaces 2-way Mirror is comparable if not slightly better than the earlier Mirror2.

     

     

     

    1 Mirror via Computer Management and 1 Parity Pool via Storage Spaces

     

    My next idea was to keep the 1st Mirror configured through Computer Management in the S2012E software while setting up my next Volume as a Parity Pool in Storage Spaces with the 2 drives that had been in the 2nd Mirror plus a 3rd drive I would add to the MicroServer. The mirror pair would again be for my critical data that would also be backed up to an external USB 3.0 drive while the Parity Pool would hold less critical data.

     

    I added an additional ST3000DM001 to Port 5 that was the 3.5” drive bay in the DuoSwap.

     

    clip_image010

     

    Above is the performance of that single drive added in the DuoSwap Port 5 of the MicroServer.

     

    I deleted the 2-way Mirror I had created in Storage Spaces and using Storage Spaces I built a Parity Pool with the 2 ST3000DM001’s that had been Mirror2 and the ST3000DM001 in the 3.5” DuoSwap.

     

    clip_image011

     

    The performance of the Parity Pool in Storage Spaces was dismal in write performance though in all fairness to MicroSoft their documentation had stated Parity Pool/Parity Spaces are designed for capacity efficiency and increased resiliency. Parity spaces are best suited for archival data and streaming media, such as music and videos. Parity Pool/Parity Spaces Read Performance does support Microsofts statement in their documentation.

     

     

     

    1 Mirror via Computer Management and 1 2-way Mirror (w/3 drives) in Storage Spaces

     

    My next idea was to keep the 1st Mirror configured through Computer Management in the S2012E software while setting up my next Volume as a 2-way Mirror in Storage Spaces with the 3 drives that had been the Parity Pool above. The mirror pair would again be for my critical data that would also be backed up to an external USB 3.0 drive while the 2-Way Mirror in Storage Spaces would hold less critical data.

     

    I deleted the Parity Pool and used the 3 ST3000DM001’s to create a 2-way Mirror in Storage Spaces.

     

    clip_image013clip_image015clip_image017clip_image019

     

    clip_image020

     

    The performance of the 3 ST3000DM001’s in a Storage Spaces 2-way Pool was substantially better than a Parity Pool. Note that this compares well with the baseline Mirror2 created in Computer Management.

     

    It is interesting to compare this performance to what I achieved with StableBit’s DrivePool with three 3TB drives in WHS-2011 (below):

    Setting up Server Backup for Critical Data and Bare Metal Restore

     

    At this point I move the Server Folders that would hold critical Data to Drive D and the less critical Data folders to Drive E. In my current plan: while Folders on D: and E: are both duplicated only the folders on D: would be backed up to an external drive for off site storage.

     

    After attaching the USB Seagate external drive it was pretty simple to step through the Server Backup menu and pick off those items I wanted backed up to an external drive for off site storage.

     

    clip_image022

    clip_image024

     

     

     

    1 2-way Mirror (w/5 drives) in Storage Spaces

     

    While the last configuration above felt safe it was also wasteful. My critical data would probably never amount to more than a few hundred GB even with some expected growth in the future with pictures and videos of my grandson and family. Yet, I was allocating 2 3TB drives in a Mirror that was also being backed up to this critical data. After all, this was also a test build with data that was a duplicate of what was on my WHS-2011 Server that was also backed up on my V1 Server. To fully test the capabilities of S2012E I decided I should go all-in with Storage Spaces and break the 1st Mirror I had created in Computer Management and move those 2 3TB drives to the 2-Way Mirror in Storage Spaces. I also chose to do this after setting up the final configuration earlier that had included setting up the Server Backup Settings to only back-up Drives C: and D: but not E:

     

    I moved all of my Server Folders on D: to E:. When you move Server Folders that are in the Back-up Pool the Wizard would prompt me to check the Back-up Pool settings to be sure the Server Folders I wanted were being backup up – which I did. Then I broke the 1st Mirror and going into Storage Spaces I added those 2 3TB drives to the existing Storage Spaces 2-way Mirror for a total of 5 3TB drives in the Storage Pool.

     

    clip_image026

     

    After that I renamed the Storage Pool from Drive E: to Drive D: -- this action caused the S2012E DashBoard to “loose” where the Server Folders were (still showing them on Drive E: even though they were on Drive D: and could be accessed through File Explorer). I rebooted S2012E and went back to the Dashboard where I had S2012E recreate the Server Folders that it had lost. S2012E recreated the Server Folders on Storage Spaces Drive D: and where it found the folders of the same name pre-existing it just merged them together. Went through the Server Backup settings and made sure that only the Server Folders I considered critical would be backed up like I had earlier planned.

     

    clip_image028

     

    Overall, I was pretty impressed how relatively easy it was to do what I wanted without messing up S2012E in the process. I was impressed with how very Robust this Server software package S2012E appears to be, IMHO.

    Conclusion

     

    clip_image043

     

    After going down the DashBoard check list the next step is to begin connecting computers (both VMs and physical machines) and compare to my experiences in WHS 2011 and V1.

     

    clip_image045clip_image047

     

    Note: When transferring my files to the S2012E build I experienced slower than anticipated file transfer rates that I was able to correct by following the instructions in Slow File Transfers Between Client and Server by Joem and Disable SMB signing on Windows 2012 Essentials by SBS-Diva.

    Performance Comparison of baseline Mirror2 created in Computer Management to Storage Spaces Pools of 2-way Mirrors and Parity:

     

    clip_image008[1]clip_image009[1]clip_image011[1]clip_image020[1]clip_image041[1]

     

    I believe the optimal configuration to continue testing S2012E in the MicroServer is with a Storage Spaces 2-way Mirror Pool made up of five 3TB drives plus the utilization of an external 3TB USB 3.0 drive for critical data backup.

     

    The external USB 3.0 drives are labeled by S2012E and in a production environment the external drive(s) could be rotated with an off-site backup location. Additional data security could be provided with a “cloud storage” solution for critical data such as CrashPlan. With an available USB 3.0 port still open and an available PCIe slot still open additional external storage could be added to the Storage Spaces 2-way Mirror Pool if additional storage was needed.

    Great post. A question... No difficulties - other than 90G minimum OS drive size - are mentioned. Nothing at all? All the drivers for the N40L are in 2012E already? __Second topic, and maybe this isn't the place for it, but I'm not really following why we want an SSD for the OS drive in a WHS. As the only drive in a laptop, sure. And faster boots for a server. But if a server is going to run for (hopefully) weeks and months without rebooting, why provision an SSD? Perhaps I'm missing something here... does the OS SSD somehow improve data performance for the spinning drives in delivering streaming video or something?

    Hey jsox! Thanks! BTW, it was great meeting you at the meet-up! You have it right -- the install went very smooth after the bump in the road with the 60GB drive. S2012E had everything -- I plugged in my 128GB Crucial M4 SSD into the DuoSwap and plugged in my external USB DVD drive in a front port when I turned RANGER on I went into the BIOS and picked the DVD drive first in the boot order -- S2012E started out on the DVD -- I went into advanced and deleted all the partitions on the SSD and then let it do it's thing. I installed S2012E on the OS drive first then I started loading in the ST3000DM001's, the first pair, the second pair, the the final one in the DuoSwap. When I was ready to set up the server backup I attached the external drive.

    The only other bump in the road was when I tried to load the x86 version of Forefront instead of the x64 – took me awhile to figure out what I’d done wrong – not enough caffeine I guess!

    You can read PCDoc’s writeup on the advantages of using a SSD for the OS in a Server at http://homeservershow.com/running-an-ssd-on-whs.h... -- in a nutshell it speeds up the loading of the dashboard and when you RDT into the Server – I do both a lot – and of course any server SW based on the OS drive will load faster. In the past I’d done some builds in the MicroServer using the HP supplied 250GB drive for the OS and for me it was like a night and day difference in the “feel” of the machine. Of course YMMV and you may not think it was worth it for you.

    Another thing to note -- this is my test/play box I had at the meet-up so it has been burned in for awhile and bounced around in my trunk going to/from indy -- and you know how we mishandled RANGER at the meet-up taking it apart ect. -- so I was probably well past any potential hardware failures of the MicroServer itself. (They're tough little boxes!)

    • 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!

    • D-Link has dropped a couple of new products and additions to their lineup of smart home gear.  Hold on because there is a lot of gear!
      Let's start with cameras.  D-Link has new Wi-Fi cameras, the Full HD Pan and Tilt Pro Wi-Fi Camera (DCS-8302LH) and Full HD Indoor and Outdoor Pro Wi-Fi Camera (DCS-8526LH).  These are not just new, and good looking cams, they can now perform people detection and glass break detection.  The new cameras also feature expanded ways for customers to save video, including ONVIF Profile S, which enables custom storage and streaming options to personal NAS devices, built-in storage microSD capacity up to 256 GB, as well as free and paid cloud storage options. 
       

       
      This year's camera models include both an indoor and an outdoor model. The outdoor model features a spotlight and siren that can be triggered when motion is detected, deterring potential intruders. The indoor model pans around to give a full 360-degree view of any room and tracks motion. Both include two-way audio. 
      Full HD Pan and Tilt Pro Wi-Fi Camera is the model (DCS-8302LH), available in Q2, 2020, and retail pricing will be $99.99.
      Full HD Indoor and Outdoor Pro Wi-Fi Camera is the model (DCS-8526LH), available in Q3, 2020, and retail pricing will be $119.99.
      One of my favorite products is Wi-Fi.  D-Link has a whole lot of new products coming including Wi-Fi 6, Mesh, Alexa and Google Assistant integration, IFTTT, Parental Controls, and more!
       

       
      There are so many new SKU's that I can't make heads or tails of them!  I'm going to be speaking with D-Link more this week and will sort all of these out. I do want you to see all they are offering and what the release date and projected retail pricing will be.

    • 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.

      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.
