Hyper-V Live Migration between Processor Generations

Rate:  

About This Video
I’ve talked before about the fact that we cannot Live Migrate from an AMD CPU to an Intel CPU or vice-versa, but what about Live Migrating from an older Intel CPU to a newer Intel CPU?  I’m going to show you a Live Migration from a three year old Intel Xeon 5050 CPU to a new Intel Xeon 3440 CPU. 

So why is the three year old CPU a 5000 series CPU and the newest CPU is a 3000 series CPU?  The 5000 series CPUs are for multi-processor configurations, the 3000 series CPUs are for single-processor configurations.  It’s the last three numbers that Intel has actually been updating as they’ve improved their processors.

The biggest reason that I put this together is that I wanted to demonstrate that customers that have an existing Hyper-V cluster can add new servers to to their existing cluster, to scale out their clusters, even with newer hardware and CPUs.  I want to make sure that I dispel the myth that your Hyper-V servers must be identical.  While identical servers do make your clusters easier to deploy and manage, as this video shows, it is possible to increase the size of your cluster over time as needed.

Until next time,
Rob
