Benjamin Franklin wrote ‘in this world nothing can be said to be certain, except death and taxes”. You may have read our article about how it is possible to cheat death in Save Lives, implement VDI. But death is a mere bagatelle in these austere times in comparison to taxes. Continue reading Can you avoid the VDI Tax?
In my virtual environment recently, I experienced two major failures. The first was with VMware vNetwork Distributed Switch and the second was related to the use of a VMware vShield. Both led to catastrophic failures, that could have easily been avoided if these two subsystems failed-safe instead of failing-closed. VMware vSphere is all about availability, but when critical systems fail like these, not even VMware HA can assist in recovery. You have to fix the problems yourself and usually by hand. Now after, the problem has been solved, and should not recur again, I began to wonder how I missed this and this led me to the total lack of information on how these subsystems actually work. So without further todo, here is how they work and what I consider to be the definition for fail-safe. Continue reading Distributed Virtual Switch Failures: Failing-Safe
I have been a big fan of VMware’s Distributed Resource Scheduler (DRS). VMware DRS is a service or feature that will dynamically allocate and balance computing resources across the hosts in a cluster. In all of the environments I have work with so far, DRS has been a fantastic tool for getting and maintaining that balance across all the hosts in a cluster. Recently though I have come across a limitation of VMware’s DRS that is worth mentioning. Continue reading Exploring a Limitation of VMware DRS
MultiPoint Server is the Cinderella of the Windows world, locked away in the cellar education sector, kept away from the bright lights of publicity and severely limited in what it could offer. But that could well be changing given Microsoft’s recent efforts to revamp the product. Although not yet quite ready for shipping, Microsoft has been working hard to add value to MultiPoint Server and when it ships in March it looks like Microsoft might have a winner on its hands. Continue reading Microsoft Windows MultiPoint Server 2011
On January 27th, VMware made some superficial and significant changes to its management team. We review those changes and which ones are important: Continue reading VMware Executive Management Team Changes – The Implications
Application Virtualization allows users to use potentially conflicting software in the same workspace. Towards the end of 2010 there was a great deal of discussion about the complexity of using application virtualization to finally let corporations end their dealings with the recalcitrant Internet Explorer 6.
