I had a question last week about multi NIC vMotion. The question was if multi NIC vMotion was a multi initiator / multi target solution. Meaning that, if available, on both the source and the destination multiple NICs are used for the vMotion / migration of a VM. Yes it is! It is complex process as we need vMotion to [...]

<edit>KB article has been published, including the video I shot</edit> How do you setup multi-NIC vMotion? I had this question 3 times in the past couple of days during workshops so I figured it was worth explaining how to do this. It is fairly straight forward to be honest and it is more or less similar to how you would [...]

I received a question last week about higher latency thresholds for vMotion… A rumor was floating around that vMotion would support RTT latency up to 10 miliseconds instead of 5. (RTT=Round Trip Time) Well this is partially true. With vSphere 5.0 Enterprise Plus this is true. With any of the versions below Enterprise Plus the supported limit is 5 miliseconds [...]

**disclaimer: this article is an out-take of our book: vSphere 5 Clustering Technical Deepdive** There are some fundamental changes when it comes to vMotion scalability and performance in vSphere 5.0. Most of these changes have one common goal: being able to vMotion ANY type of workload. It doesn’t matter if you have a virtual machine with 32GB of memory that [...]

vSphere 5.0 has many new compelling features and enhancements. Sometimes though it is that little tiny enhancement that makes life easier. In this case I am talking about a tiny enhancements for vMotion which I know many of you will appreciate. It is something that both Frank Denneman and I have addressed multiple times with our engineers and finally made [...]

I was reading up on vMotion today and stumbled on this excellent article by my colleague Kyle Gleed and noticed something that hardly anyone has blogged about…. Quick Resume. Quick Resume is a feature that allows you to vMotion a virtual machine which has a high memory page change rate. Basically when the change rate of your memory pages exceeds [...]

There is something I always wanted to know and that is how VMotion(yes I am using the old school name on purpose) came to life. After some research on the internet and even on the internal websites I noticed that there are hardly any details to be found. Now this might be because the story isn’t as exciting as we [...]
