Introduction
The values provided in this guide should not be interpreted as theoretical system limits for Cisco Nexus 3000 Series hardware or Cisco NX-OS software. These limits refer to values that have been validated by Cisco. They can increase over time as more testing and validation is done.
Verified Scalability Limits
The tables in this section list the Cisco verified scalability limits for Cisco NX-OS Release 7.0(3)I7(7). The values provided in these tables focus on the scalability of one particular feature at a time.
Each number is the absolute maximum currently supported by this Cisco NX-OS release for the corresponding feature. If the hardware is capable of a higher scale, future software releases might increase this verified maximum limit. Results might differ from the values listed here when trying to achieve maximum scalability with multiple features enabled.
