Which NetApp best practice should be followed when configuring interface groups for SMB performance and resiliency?

• A. Use ports from the same NIC
• B. Use ports on different NICs
• C. Use ports with the same chipset
• D. Use ports from different NICs

Answer: (D)

For SMB performance and resiliency, you want path diversity. Building an interface group with ports from different NICs gives you multiple independent network paths for SMB traffic. If one NIC or its link encounters a problem, the other NICs in the group can continue carrying traffic, so SMB remains up and performing. Using ports from the same NIC creates a single point of failure—if that NIC, its driver, or its connected switch path has an issue, all paths in the group can be affected, hurting both availability and throughput. Spreading across different NICs also helps distribute load across separate adapters, which further improves utilization and resilience. While NICs from the same chipset might still work, the key idea is physical diversity of the NICs used in the interface group to maximize uptime and performance. Therefore, select ports from different NICs.
