What are Best Practices for Network Configuration for ONTAP?
Applies to
- ONTAP 9
- Data ONTAP 7
Answer
- Use virtual LANs (VLANs) to logically separate/isolate traffic on layer 2 , mainly for security purposes and reducing complexity when troubleshooting. Use cases can be among others by type (e.g. data, management) or service (Frontend-webhost, SQL Server 1a, Kubernetes Cluster X) or department/team (e.g. HR, IT, Support): Configure VLANs over physical ports (netapp.com)
- Networking Best Practices for ONTAP 9 are in the respective sections in Ethernet Storage Design Considerations, Best Practices for Clustered Data ONTAP | TR-4182
Examples:
- Use Failover Groups instead of single mode interface groups (ifgrps) (p. 12, single mode)
- Disable flow control on all cluster network ports in an ONTAP cluster. No recommendations for other network ports. (p. 30, Ethernet Flow Control)
