VxRail Stretched cluster 1 site failure

Hi,

I would like to know if a Vxrail stretched cluster made from 4+4+1 (FTT=1) configuration and assume 1 site (4 hosts) totally down:

• Will the vsan perform rebalanced/rebuilt on the 2nd Site (all lump together in 2nd Fault Domain Site)
• How many nodes that is acceptable to failed on 2nd site before the entire vsan cluster un-accessible (assuming the storage capacity from 1 node is enough to keep all the data)?
