This section provides verified scalability values for various deployment types for Cisco Nexus Dashboard Fabric Controller, Release 12.0.1a.

The values are validated on testbeds that are enabled with a reasonable number of features and aren’t theoretical system limits for Cisco Nexus Dashboard Fabric Controller software or Cisco Nexus/MDS switch hardware and software. When you try to achieve maximum scalability by scaling multiple features at the same time, results might differ from the values that are listed here.
