Modernizing Your Infrastructure with Hybrid #Cloud | Part 8

Hyper-V over SMB

imageIn today’s post in the modernizing your infrastructure with Hybrid Cloud series, I am going to talk about Hyper-V over SMB, which we introduced in Windows Server 2012.  It is also important to note that you can use storage spaces to house your SMB share that Hyper-V will leveraged.  In Part 7 I talked about storage spaces:  Modernizing Your Infrastructure with Hybrid Cloud - Storage Spaces in Windows Server 2012 R2 (Part7)

With Windows Server 2012 R2, we have improved the SMB protocol and it is a new version SMB 3.02.  I will start this article with a quick review of SMB 3.0 and talk about the improvements that can be found in SMB 3.02 which is included in Windows Server 2012 R2

SMB 3.0 Review

In Windows Server 2012 we introduced the next version of SMB 3.0.  The SMB protocol, essentially allows applications or the user of an applications to access files and other remote server side resources.   This allows the basic operations like working with files, reading, writing, accessing…etc.   It can also communicate with any server program that is set up to receive an SMB client request.   Two of the most important features we introduced into SMB are Microsoft SQL Server over SMB  and Hyper-V over SMB (we will get to that in a second).  We also included  several other new features:

  • SMB Transparent Failover
  • SMB Scale Out
  • SMB Multichannel
  • SMB Direct
  • Performance Counters for server applications
  • Performance optimizations (Improved)
  • SMB-specific Windows PowerShell cmdlets
  • SMB Encryption
  • SMB Directory Leasing

I wrote about these in a post I did a while back:
31 Days of Our Favorite Things- SMB 3.0 the Glue in Windows Server 2012 (Part 17 of 31)

SMB 3.02 Quick Look

In Windows Server 2012 R2 we have updated SMB to version  3.02.  A good list of what is new can be found here: What's New in SMB. There are several new and improved functionalities in the protocol including:

  • Improved performance of SMB Direct (SMB over RDMA)
  • Improved SMB event messages
  • VHDX files as shared storage for guest clustering
  • Hyper-V Live Migration over SMB
  • Improved SMB bandwidth management
  • Support for multiple SMB instances on a Scale-Out File Server
  • SMB 1.0 is now an optional feature

Probably the most important enhancement we put into the SMB 3.02 protocol is the ability to do Automatic rebalancing of Scale-Out File Server clients!

In SMB 3.0 we had the ability to use Scale-Out-File Servers.  In Windows Server 2012, SMB clients would be randomly directed via DNS Round Robin to a node of the cluster.  Then once that node was selected they would use that for all the shares they wanted to access and all their traffic would be going to that particular file server.  With Automatic rebalancing of Scale-Out File Server clients change how they connect to file servers. SMB client connections are tracked per file share (instead of per server), and clients are then redirected to the cluster node with the best access to the volume used by the file share. This improves efficiency by reducing redirection traffic between file server nodes. Clients are redirected following an initial connection and when cluster storage is reconfigured.  What that essentially means is the client will leverage the best server for the file share they are looking to use.  Jose Barreto wrote an excellent post going into some great comparisons for this new feature:  Automatic SMB Scale-Out Rebalancing in Windows Server 2012 R2

If you want to learn more about SMB 3.02, my buddy Keith wrote a great post here: Why R2- Your Next SAN with SMB 3.02 Scale-out File Servers

Hyper-V over SMB
Now let’s take this to next level with Hyper-V.  In Windows Server 2012 R2 you can now store virtual machine files, such as configuration, Virtual hard disk (VHD) files, and snapshots, in file shares over the SMB 3.0 protocol. This can be used for both stand-alone file servers and clustered file servers that use Hyper-V together with shared file storage for the cluster.  By leveraging two new features of SMB 3.0 (SMB Direct and SMB Multichannel) on a file server hosting the VHDX drives for your Hyper-V cluster, you can see storage performance on your Hyper-V guests that approaches that of a built-in server storage.  Not only that, but those Hyper-V guests enjoy the resiliency of a failover network to help avoid any outages.    Taking this even a step further with your virtual machine stored on an SMB file share. You can then perform a live migration on this virtual machine, running between non-clustered Hyper‑V hosts while the virtual machine’s storage remains on the central SMB share. This lets you use the benefits of virtual machine mobility without investing in clustering infrastructure. Hosting providers and similar environments frequently need this capability.   All provided courtesy of this wonderful protocol and take a look at the graphic for some examples:

Configuring Hyper-V over SMB
Overall the process of creating a virtual machine on an SMB is very straight forward:

  1. Install the Hyper-V role on a Windows Server 2012 R2 machine
  2. Install the File Services role on a Windows Server 2012 R2 machine
  3. Create an SMB file share and set permissions.
  4. Create a virtual machine and virtual machine hard disk on the file share, use a UNC path for the location i.e. \\servername\sharename

Then viola you’re done!  The only tricky part and really it is not that tricky is to set permissions on the share and the NTFS folder.   For this to work properly, you will need to set full permissions on the NTFS folder for the following accounts:

  • Hyper-V Administrator
  • Computer Account(s) of the Hyper-V hosts
  • If Hyper-V is clustered you will also need the Hyper-V Cluster Account (CNO)

The reason I mention security is because of traditional SAN and NAS solutions.  These solutions commonly use some type of security system to help ensure that only authorized hosts have access to shared storage – such as LUN masking in Fiber Channel SANs, initiator lists in iSCSI SANs and access lists for NFS NAS devices.

With SMB 3.02, we’ve streamlined the security model used to provide authorized access to shared storage by aligning it to the well-understood NTFS security capabilities already used in many organizations for securing application data.

Here is a great video talking about some of the considerations when doing Hyper-V over SMB:

Using PowerShell for Hyper-V over SMB

You can do this easily enough in PowerShell.  The following sequence will create a folder on the F: drive called VMS.  In step 2 you will create a share and set full access permissions for the administrator account HAdmin in the Dom domain, two Hyper-V hosts (HV1, HV2 and since this is on a cluster, HVC for the cluster host:

  1. Create Folder 
    • MD F:\VMS
  2. Create Share
    • New-SmbShare -Name VMS -Path F:\VMS -FullAccess Dom\HAdmin, Dom\HV1$, Dom\HV2$, Dom\HVC$
      -Note: the $ after the names designates those as computer names so we can use them in this command.
  3. Apply Share permissions to NTFS Folder permissions: 
    • (Get-SmbShare –Name VMS).PresetPathAcl | Set-Acl

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...
We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
Connected devices and the Internet of Things are getting significant momentum in 2014. In his session at Internet of @ThingsExpo, Jim Hunter, Chief Scientist & Technology Evangelist at Greenwave Systems, examined three key elements that together will drive mass adoption of the IoT before the end of 2015. The first element is the recent advent of robust open source protocols (like AllJoyn and WebRTC) that facilitate M2M communication. The second is broad availability of flexible, cost-effective storage designed to handle the massive surge in back-end data in a world where timely analytics is e...

After data was collected and structured, two major areas needed to be addressed: improving developer workflows and extending access to a business application to multiple users (multi-tenancy). Docker, a container technology, was used to ...
The true value of the Internet of Things (IoT) lies not just in the data, but through the services that protect the data, perform the analysis and present findings in a usable way. With many IoT elements rooted in traditional IT components, Big Data and IoT isn’t just a play for enterprise. In fact, the IoT presents SMBs with the prospect of launching entirely new activities and exploring innovative areas. CompTIA research identifies several areas where IoT is expected to have the greatest impact.
The 4th International Internet of @ThingsExpo, co-located with the 17th International Cloud Expo - to be held November 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA - announces that its Call for Papers is open. The Internet of Things (IoT) is the biggest idea since the creation of the Worldwide Web more than 20 years ago.
The Industrial Internet revolution is now underway, enabled by connected machines and billions of devices that communicate and collaborate. The massive amounts of Big Data requiring real-time analysis is flooding legacy IT systems and giving way to cloud environments that can handle the unpredictable workloads. Yet many barriers remain until we can fully realize the opportunities and benefits from the convergence of machines and devices with Big Data and the cloud, including interoperability, data security and privacy.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
The Internet of Things is not only adding billions of sensors and billions of terabytes to the Internet. It is also forcing a fundamental change in the way we envision Information Technology. For the first time, more data is being created by devices at the edge of the Internet rather than from centralized systems. What does this mean for today's IT professional? In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists will addresses this very serious issue of profound change in the industry.
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...
An entirely new security model is needed for the Internet of Things, or is it? Can we save some old and tested controls for this new and different environment?

While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehe...
