Why Can’t I Have A Stretched VMware Horizon View Cluster?

For those of you who are involved in the architecture of Horizon View environments, I'm sure you this is a question you've always asked, but may have only ever got the response of "VMware doesn't support that design". Why doesn't VMware support this design? It works….most of the time?

During my time at VMware I've heard many different reasons as to why VMware does not support this design. Finally I have an accurate reason and wanted to share it with you.

What is a stretched VMware Horizon View cluster?

For those of who are asking yourselves, "What is a stretched VMware Horizon View cluster?", I'll set the scene a little. A stretched Horizon View cluster is when a single View Pod (cluster of View Connection Severs), spans more than one physical location connected by WAN / MAN / MLAN and NOT by a LAN.

An example of a stretched Horizon View Cluster:

Stretched Horizon View Cluster

After an internal discussion around this subject, a colleague and good friend of mine Mike Barnett, who used to be an Escalation Engineer in VMware's GSS (Global Support Services) set the record straight for us. 

So I've decide to adapt his explanation and share it with you.  Read the rest of this entry »

VMware Horizon View: New Technical White Papers

Technical White PapersOver the past few week or so VMware has release some really useful technical white papers focused around VMware Horizon View. I just wanted to bring these to your attention in case you messed the announcements.

If you have an Horizon View environment, I would highly recommend you give these papers a read to ensure you are following all of the VMware's latest "Best Practices" that are appropriate for your environment.

My First Published Technical White Paper

Virtual Machine Graphics Acceleration Deployment GuideToday my first official technical white paper got released on VMware.com – titled, Virtual Machine Graphics Acceleration Deployment Guide. It's been a long time coming. It was one of those papers where I could keep adding and adding to it.

The paper talks about the following topics:

  • Why 3D Matters for VMware Horizon View
  • Understanding the Differences Between Soft 3D/SVGA, vDGA and vSGA
  • Prerequisites
  • Application Requirements and Use Cases
  • vSGA Installation
  • vDGA Installation (Tech Preview)
  • VMware Horizon View Pool Configuration for vSGA
  • Performance Tuning Tips
  • Resource Monitoring
  • Troubleshooting

Hopefully it should cover everything you need to enable your Horizon View desktops for 3D rendering.

There are a number of other VMware Horizon View: New Technical White Papers that have been released recently that are well worth a read. Check.Them.Out

How Can I Run Multiple VMware Horizon View Clients At Once?

Horizon View ClientSomething I get asked regularly is, "How Can I Run Multiple VMware Horizon View Clients At Once?", so I thought I'd just put a quick post out in the hope that in the future people will come across this post before having to ask. Quite often users would like to have multiple View sessions open at once on the screen or across screens. By default the Horizon View client only allows you to see a single View session at any one time. You can swap between multiple sessions, but you will still only be able to see a single session at any one time. This is how you can run multiple VMware Horizon View clients at once.  Read the rest of this entry »

vOpenData – Get Involved!!

vOpenData LogoA few weeks ago my RSS feeds were inundated with posts about vOpenData. I had decided to wait until the hype had died down a bit until I created a little reminder post to help keep the momentum going.

What is vOpenData?

vOpenData is an open community project that grew from the question "What is the average VMDK size for deployed virtual machines?" We wanted to create an open community database that is purely driven by users submitting their virtual infrastructure configurations. Leveraging the powerful virtualization community and applying simple analytics we are able to provide various trending statistics and data for virtualized environments. This is 100% community driven and the results will be available for everyone to view and hopefully you will contribute to the overall dataset!

Personally I think this is a great idea. The more people that anonymously share their stats, the better and more granular results will become available to us. 

Below you can see some of the data that is available via the vOpenData website.

Pre-populate VMware Horizon Data Accounts With Documents

Horizon DataThis is a little tip for anyone who is looking to pre-populate VMware Horizon Data with documents. Every user that is provisioned onto Horizon Data will automatically get these documents in their share. A common use case for this, is adding a "Getting Started" PDF document that explains how Horizon Data works, where everything is etc. You could also use this to share files to new users, company handbook, HR documents that sort of thing.

VMware Horizon View 5.2: Network Ports (Internal Design)

I've been doing some work internally at VMware which I thought could be useful to the wider public, so I've decided to share this with you.

I've put together a couple of detailed diagrams that display the networking port requirements and directional traffic flow to the various component that make up an Horizon View 5.2 environment. Some of the diagram's I've seen documented in the past don't always show everything that is required and customers can often encounter issues when important information is missing.

I've decided to split these diagrams out into to separate posts. Here is the internal design Horizon View design.
