Description
Our Blockstore DB recommended setup provides a naive approach by specifying just 2 data nodes. This organically implies that we can run MMS Backup in 2+1 topology for the Blockstore DB.
Since MMS uses w=2 write concern this also implies that anyone using this setup would be susceptible to loss of write availability on Backup if they loose one of the data notes.
We should enhance our documentation to make this clear in the recommended setup as well as any other place discussing high availability.
