Verified Scalability
for Cisco Dynamic Fabric Automation
This chapter contains the following sections:
- Overview of Verified Scalability
- Verified Scalability for a Cisco DFA Fabric
- Verified Scalability for Cisco DFA Leaf Switch
- Verified Scalability for Cisco DFA Border Leaf Switch
Overview of Verified Scalability
This document lists the Cisco verified scalability limits for a Cisco Dynamic Fabric Automation (DFA) deployment.
In the following tables, the Verified Topology column lists the verified scaling capabilities with all listed features enabled at the same time. The numbers listed here exceed those used by most customers in their topologies. The scale numbers listed here are not the maximum verified values if each feature is viewed in isolation.
The Verified Maximum column lists the maximum scale capability tested for the corresponding feature individually. This number is the absolute maximum currently supported by the Cisco NX-OS release software for the corresponding feature. If the hardware is capable of a higher scale, future software releases might increase this verified maximum limit.
