Chapter 1. Cisco Nexus Dashboard Fabric Controller Verified Scalability

- Verified Scale Limits for Release 12.0.1a

Verified Scale Limits for Release 12.0.1a

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.
