Creating an automated VMware Horizon RDS Pool with Horizon 6.2

 

horizonSo VMware Horizon 6.2 was announced at VMworld just a week ago and the one feature I sorely wanted to see was automated provisioning (golden image management) of a Microsoft Remote Desktop Services farm.

The provisioning process is fairly straight forward, so in this blog post I’ll walk you through the steps to avoid any issues.

Prerequisites:

  • Download the Agent, Connection Server and Composer software.
  • Upgrade your Connection Servers to 6.2.
  • Upgrade your Security Servers to 6.2 (remember you’ll need to repair with the connection servers).
  • Upgrade your Composer.
  • A Microsoft RDS server.

ThinIO facts and figures, Part 3: RDS and Ram caching.

logoWelcome back to the third instalment of this blog series focusing on our new technology ThinIO!

To recap, below you will find the previous articles:

Off topic note:

two years ago at an E2EVC event, the concept behind ThinIO was born with just a mad scientist idea amongst peers.

If you are lucky enough to be attending E2EVC this weekend, David and I will be there presenting ThinIO and maybe, just maybe there will be an announcement. Our session is on Saturday at 15:30 so pop by, you won’t be disappointed.

Back on topic:

So here’s a really interesting blog post. Remote Desktop Services (XenApp / XenDesktop hosted shared) or whatever you like to call it. RDS really presents a fun caching platform for us, as it allows us to deal with a much higher IO volume and achieve deeper savings.

We’ve really tested the heck out of this platform for how we perform on Microsoft RDS, Horizon View RDS integration and Citrix XenSplitPersonality with Machine Creation Services.

The figures we are sharing today are based on the following configuration and load test:

  • Logo_Login_VSI_TransparentCitrix XenDesktop 7.6
  • Windows Server 2012 r2
  • Citrix User Profile Manager.
  • 16gb of Ram.
  • 4 vCpu.
  • LoginVSI 4.1 medium workload 1 hour test.
  • 10 users.
  • VMFS 5 volume.

Fun figures!

Diving straight in, lets start by looking at the volume of savings across three cache types.

ThinIO facts and figures, Part 1: VDI and Ram caching.

Alogos we draw ever closer to ThinIO’s big day, I thought I’d put a blog post together talking about the RAM caching, statistics, facts and figures we’ve baked into version 1 to deliver some really kick ass performance improvements with even the smallest of allocations of cache per VM.

Test, test, review and tune. Rinse and repeat!

We’ve spent months load testing, tuning, fixing and retesting ThinIO. And for the first time we’re going to start talking about the dramatic results ThinIO can have on storage scalability and user perceived performance.

During our extensive testing cycles, we’ve covered:

• Horizon View
• Citrix XenDesktop
• Microsoft RDS

We’ve been seeing very similar, if not identical results when testing against pools on the following storage types too:

• XenServer SR
• VMFS
• NFS
• Microsoft Clustered Shared Volumes

ThinIO Public Beta is go!

logoLets get right to it!

Warm up your labs or fire up your golden images ladies and gents, we’re delighted to announce ThinIO’s brief public beta will begin today!

This project has taught us some really interesting things about Windows IO, how Windows behaves and how the hypervisor and storage can behave. This project really felt like a David vs. Goliath task as we (members of our community with a desire to simplify this issue) attempted to tackle one of the largest issues in our industry, storage bottlenecks and Windows desktops.

What’s really unique about our approach is there are no hardware lead times, no architecture changes needed and no external dependencies. ThinIO can be installed in seconds and the benefits are seen immediately.

HDXWatcher and PCOIPWatcher – Realtime, easy virtual desktop traffic reporting.

logoWhen checking the bandwidth requirement of multimedia sites, checking how much additional bandwidth video conferencing is going to require or even troubleshooting WAN capacity issues, it’s extremely useful to have a visible interpretation of realtime bandwidth consumption from your virtual desktop.

I wrote a tool quite some time ago called watcher2 while troubleshooting a similar issue. I finally took the time to refactor that tool for use with XenApp 6.5 , XenDesktop and VMware View and they are finally available to download! Both watcher utilities also include a latency counter which was a request that came in over and over.

HDX and PCOIP watcher by default dock to the top of the screen and can be moved left or right as below:

They can now also be completely un docked:
