Cassandra failover vs other databases?

Cassandra offers controlled consistency, for example, "write to 2 nodes and tell me how to do this." Two "main" nodes and some slaves provide good system fault tolerance.

MongoDB offers replication pairs - simmilar failover force as cassandra? Is there any other database with this functionality?

Cassandra is a fully distributed system, so there is no need for explicit fault tolerance. If the machine sends requests for stamps, you simply connect to another (RRDNS, haproxy, any method is OK). Even the loss of entire data centers is carried out by Cassandra without your application, which should take care.
