all tables are translated to an ordered KV store and then broken down into 64MB ranges, which are then used as replicas in RAFT

Sharding, horizontal partitioning

tables can be distributed across several files (horizontal partitioning); sharding through federation

Methods for redundantly storing data on multiple nodes

none

Multi-source replication using RAFT

yes

yes, but depending on the SQL-Server Edition
