In this industry when somebody says ‘boot storms!’ – most of us will respond with:
Boot storms are a well documented, boring problem and have many solutions available from vendors and hypervisors alike. Most solutions today rely on a ‘shared memory’ storage area to cache ‘on boot’, in theory caching only one startup or one pattern in order to then serve it back to the proceeding desktops to boot.
But why are boot storms an issue? While working on ThinIO we had the unique ability to really dive into the Windows boot process and analyse why boot storms cause the damage they do and in this post we thought we’d share our findings to better document the issue.
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.
When 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:
Thinkiosk Version 4.0 is the culmination of 9 months hard work, rebuilding ThinKiosk in a new development style to include the enterprise features many of you requested, adding a management server, secure key redirection technologies, local group policy control and a number of other features. After weeks of rigorous testing we’re delighted to announce the availability of ThinKiosk version 4… Today!
With the release of Version 4.0 we’re lifting the cloak on the company we’ve setup in order to support and further develop ThinKiosk, ThinScale Technology. We’ve set up ThinScale as a little software company to publish applications to the virtualisation community, tackling the smaller issues and annoyances we face day to day as consultants and administrators. More clever little products are in the pipeline, but for now enough about the company! Continue reading →
