ThinKiosk 4.5 is here!

ThinKioskJust a quick blog post to let you know ThinKiosk 4.5 is here and with it comes a huge list of new features and functionality requested by you.

ThinKiosk 4.5 is a big update, so without further ado, lets get right to it:

ThinKiosk Broker Service:

  • HA features are now available in the ThinKiosk Broker.
  • The Broker service can now utilise Microsoft SQL for the database and an easy migration utility can be utilised to do so.
  • Brokers can now be load balanced via Citrix Netscaler or Microsoft DNS round robin.
  • The ThinKiosk Broker can now deliver software updates directly to clients.
  • The ThinKiosk Broker can now authenticate against active directory.

ThinKiosk Client:

  • The ThinKiosk receiver functionality has been moved to the applications tab in our new ThinScale Connector functionality.
  • The Client can now communicate directly with Microsoft RDS Broker services. Allowing customers using Microsoft RDS or VDI to use ThinKiosk to connect, enumerate and launch resources within ThinKiosk, without RDP files.
  • The Client now supports password changing and legal notices for the ThinScale Connector.
  • The Client now supports “auto launch” logic to specify which desktops to auto launch on logon.
  • The Client now starts up at least 40% quicker than previous versions.
  • The Client’s communication logic has been redesigned to allow management even when nobody is logged in.
  • The Client now supports central software updates from the Broker, allowing push software updates.
  • The Client now has an authentication API for use with Imprivata tap and go cards or similar technology.
  • The Client is now smart enough to detect DNS round robin when connecting to a Broker and will use the list retrieved from DNS as a broker list to try when starting up.
  • The Clients will delete stale or old user profiles periodically to keep machines clean.
  • Many, many improved administrative features allowing ease of access to the system for administrators.

 

We’re extremely proud of this update and we look forward to hearing from you!

 

ThinIO facts and figures, Part 4: Storage design and dangerous assumptions.  

Welcome back to this blog series discussing our new product ThinIO. Please find the below three earlier articles in this series:

In the final blog post in this series, we’re going to discuss storage design and a frequent problem face when sizing storage. Lets get right into it:

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, taking a peak under the covers.

logoWhat a busy few weeks, Citrix Synergy already feels like a distant memory. We had a great trip and were dumbfounded by the interest and excitement shown by enthusiasts, customers and vendors around our ThinIO solution, with quite a few people insisting on seeing the inner mechanics and trying to break our demo’s to ensure the figures they saw were legit!

For those unfortunate enough to miss synergy or our Webinar with Erik over at XenAppBlog, here’s a little blog post you will find interesting as I walk you through the inners of ThinIO and why it’s so simple to deliver disk access with RAM speeds without any of the complexity.
