EUC TIP 89: Embarrassingly Parallel Processing for Microsoft RDS

Hyper-V 2012 defaults to deploying VM’s one at time, slow and steady. If you think about it, that can be a lot if you have a 64 host cluster you are deploying desktops too. Nutanix runs a virtual storage controller on each node/server so we handle a little bit of blunt force trauma without wiping out the rest of the workloads. You can refer to my mixed workload post to get the specifics.

Hyper-V and VDI on Nutanix: Part 1

Screen Shot 2013-12-13 at 10.03.10 AM

If you’re a regular visitor to the blog you know that I have lived in the lands of VMware VDM, View, Horizon and probably whatever the next name is. I wanted to deploy Remote Desktop Services on Hyper-V since requests from the field has started to come since we announced support for Hyper-V.

You still get the same quick time to value as you did from vSphere deployments on Nutanix, not a lot of changes it that department. Nutanix engineers did add some deployments scripts that automate adding the cluster to the domain and to SCCVM if present.

Horizon View 5.2 & Lync 2013 Support – Are You Covered?

I think it’s amazing that VMware and Microsoft are working together to support Horizon View 5.2 and Lync 2013. From my understanding the two companies have only come together since last summer so this is great work at bringing the engineering teams together. The problem though for most enterprises that I see is the deployment of Zero Clients, which is will not supported for Lync 2013 when View 5.2 goes GA.

Lync 2013 features with VMware View desktops

Presence Supported
Instant Message Supported
Desktop Sharing Supported
Application Sharing Supported
PowerPoint Sharing Supported
Whiteboards Supported
File transfer Supported
Online meetings Supported
Office Integration Supported
Audio Supported (with Lync 2010, this used to only be supported via IP-Phone)
Video Supported (with Lync 2010, this was never supported)
Recording audio


You will have to deploy Lync software components on your virtual machines and client devices. So the client devices can only be Windows 7 or Windows 8 devices.

Lync 2013 and View 5.2

Different components of the VMware View and Microsoft Lync 2013 architecture

The Lync VDI plugin that runs on the Windows client needs to be at least have 1.5GHz CPU and minimum of 2GB RAM.

On your Lync Server 2013, ensure that EnableMediaRedirection is set to TRUE for all VDI users. As part of the Lync Server setup, make sure you generate a certificate and add this certificate to their Windows Client Machine. The certificate will need to be placed in the “Trusted Root Certificate Authorities” directory. The Lync VDI 2013 plugin will not pair up with the Lync 2013 client running inside the remote desktop if this step is not completed. You may also have to place a host file on the endpoint if the endpoint is not on the same domain as the Lync Server.

It’s also good point out you want to make sure the USB headsets and WebCams are not redirected to the VM. You want the traffic to go between the clients via the plugin.

Overall the Lync 2013 support is great but just make sure you know that zero clients are still not covered. Zero clients will still suffer from hair-pinning traffic in the datacenter and not get the benefits of WAN optimization for Voice traffic. Zero Clients can still work you just really need to nail down the Network Best Practices for PCoIP. Other clients will be added but it appears the ball is in Microsoft court. Microsoft still needs to provides it’s components to the other clients but Zero client support seem away down the road.


Unidesk Saves Cache

From an applications perspective I have been a liked Unidesk for awhile. ThinApp is good but unless you have a dedicated person for the role, hard applications can stall VDI projects waiting from them to be packaged. Don’t get me wrong, ThinApp has its place. If you need multiple versions of applications running on the same platform ThinApp is the way to go. ThinApp is also a must if you want to role out Horizon from VMware.

I think it’s important also to point out Unidesk can lower View implementation costs by allowing the customer to save on storage costs without having to pay the premium price for View Composer. On the XenDesktop side of the house, you wouldn’t have to use Machine Creation Services(MCS). From the XenDesktop people I have talked to, MCS doesn’t scale well.

Simplicity VS Frankensteinism

While Nutanix was launching NOS 3.0 and the new hardware line I was still thinking the 2.6.3 software release was pretty damm good. Of course 2.6.3 embodies what a great design should entail. Simple and easy to maintain. It does no one any good to build something that is so complicated that 3 months later after installation it is falling apart. Configuration drift and no one wanting to touch it from fear of breaking it are true problems on the operate side of the house.

Squeezing the Last Drop for VDI and HPC – Nutanix’s Replication Factor

So I apologize in advance to the Nutanix Support team. The beauty of Nutanix with its Google like file system, NDFS(Nutanix Distributed File System) is the ease of use with performance. A distributed architecture that scales and massive parallelism at 25,000 IOPS a block is a lot to handle but some people are just plain greedy. If you see the work that Jim Moyle has done with Windows 7, you realize a Win 7 desktop will eat as many IOPS it can get it’s hands on.

#EUC Tip 80: VDI with Time Sharing, Spin Down VDI, Spin UP Cloud\Hadoop

Don’t let all of the those expensive CPU cycles go to waste. On the weekends and during off hours spin down your VDI environment and run some other workloads like vCloud Director or Hadoop(Project Serengeti). Code below is kinda simple but that’s what makes PowerShell awesome I guess. To schedule the code to run vist

WARNING: Before running code you find on the Internet, test, test, test
