   The fields in the new keyspace window are described below:  
   

   Field	Description
   Name	Name of the keyspace. This field is mandatory. The name "system" is reserved for Cassandra internals.
   Replication Factor	Number of replicas (additional copies) of keyspace data stored in a Cassandra cluster. For example, if replication factor is set to 2, then 2 nodes in the cluster will have copies of keyspace data and this replication is transparent to the clients. The replication factor should not exceed the number of nodes in the cluster.
   Replication Placement Strategy	Replica placement strategy determines how the keyspace data copies are placed in the Cassandra cluster, which nodes carry copies of which keys etc. We have the 'Simple' Strategy, 'Old Network Topology' Strategy and 'Network Topology' Strategy.

3. The added keyspace is listed under Keyspaces.
   Storage Server has the system keyspace by default. It is the metadata table used by Cassandra server, and users are not allowed to modify it.
4. You can perform the following operations on the newly-added custom keyspace.
