Distributed Virtual Switch Failures: Failing-Safe

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.

Microsoft Windows MultiPoint Server 2011

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.

Mobile malware reinforces need for mobile hypervisors

At last year’s VMworld in San Francisco Stephen Deasy (Director, R&D, VMware) and Srinivas Krishnamurti (Senior Director, Mobile Solutions, VMware) announced VMware’s plans for a type II mobile hypervisor platform. Three months later VMware and LG have announced a partnership to install VMware Mobile Virtualization Platform (MVP) on LG smart phones starting in 2011. While significant questions remain about the viability of this partnership, the need for a mobile virtualization solution cannot be stressed enough.

Monitoring from the Cloud

I have started the year 2011 out by looking at some of the different monitoring solutions available for us to have an insight into the health and welfare of the systems that we support. In your typical monitoring solution you would install the monitoring server in your environment and let the system discover all the devices in your infrastructure and or to control the licenses we would manually enter the devices that we want to monitor. Some of these monitoring servers solutions have to have a beefy box to begin with and all solutions will need a great deal of “tweaking” to control the number of false positives as well as time put in to be able to report on what exactly we care to be alerted about.

Want to Move to the Cloud? Simple Steps

You heard the buzzwords and drunk the kool-aid and now you want to move to the cloud, how do you do this? This has been the a fairly interesting question on the VMware Communities Podcast yesterday, when the vCloud team showed up to talk about the current reference architecture. Yet almost all the questions were about going to the cloud and not about the architecture. Does this mean people do not understand what is required to go to the cloud? I think so. So to take a few elements from the podcast and put them in writing is the goal of this article. The Simple Steps to move to the cloud.
