Storage VMotion is a critical part of the business processes now. Everytime we can with confidence use a new functionality like this to keep downtime to a minimum we go with it.

Been using Storage VMotion for close to a year now. Can’t wait to hit vSphere 4 and not use a plugin.

Tim, I like the “without an outage” part.

“But seriously — are you using Storage VMotion to move production virtual machines?”

YES! As little as possible but when necessary I won’t hesitate. In the process of a storage migration I’ve used svmotion on all of my vms. I’ve definitely seen the process fail in a couple of different fashion but I’ve always been able to recover without an outage.

If I remember correctly, this is the same type of thing we heard from MS about VMotion.

In the last 3 months I have done over 80 sVmotions of productions guest without a problem.

I remember many articles referencing this feature and I certainly remember the boisterous words of the Kroll supporter you are referring to. He strikes me as someone who could be paid to believe his own lies.

“But seriously — are you using Storage VMotion to move production virtual machines?”

Are you kidding ? Who is *not* using sVMotion ?

You should invert the question to , “Is someone NOT using storage vMotion” ?

It is a joke MS to say it is not secure after so many time running on production environments.
