Cassandra snitches
A snitch determines which data center and rack nodes belong. Snitches notifies Cassandra about the network topology, so that requests are efficient and Cassandra distributed through the grouping of machines to replicate data to individual data nodes and racks. Replication policies are based on the information provided by the new snitch to the replication data. All nodes must return to the same rack and data center. Cassandra does not allow more than one block of data to be on the same rack.

Note: If you change Snitchs, you should take extra steps because snitch affects the copy storage
