First lets look at what PernixData FVP actually does.  The video below describes how FVP works.  I am not going into all the details about PernixData FVP that’s Frank’s job.

So how do we ensure data protection? VMware VSAN uses Storage policies to do this. These can be found in vCenter Home -> Rules and Profiles -> VM Storage Profiles. Using VM Storage Profiles you can assign capabilities to storage. In a Cloud environment, we like to use Gold, Silver and Bronze to determine our storage capabilities. We can easily create these policies to now match the capabilities of the storage. We have a number […]
