vSAN is not a VSA
This vSAN is not a VSA infact you can enable it simply by checking a box. An great overview of vSan can be found here: http://www.yellow-bricks.com/2013/08/26/introduction-vmware-vsphere-virtual-san/
Personally, I think the vSan is a great addition next to your existing storage, you can add low cost SSD local disks in your servers and use vSAN to create a Tier 1 Datastore to store swap files
Biting the hand that feeds IT
