Good morning, RAID 6 provides FTT = 2 and uses 1.5 times the space.  For performance with RAID and dedupe enabled, see this VMware blog:  Virtual SAN 6.2 Performance with OLTP and VDI Workloads - VMware VROOM! Blog - VMware Blogs

As for CPU/Memory overhead, I can't find anything specific; but here are two good articles on the features in general.  Thank you, Zach.
