NetApp Exam NS0-304 Topic 5 Question 26 Discussion

When adding a new AFF A250 to an existing 4-node cluster with cloud tiering enabled to AWS, a minimum of two logical interface (LIF) configurations are necessary for the tiering process. Here's the rationale:

LIF Configuration for Cloud Tiering: Each node in a NetApp cluster typically requires a minimum of one data LIF for client access and an additional LIF for inter-cluster communication. However, for cloud tiering purposes specifically, at least one data LIF per node is essential to manage the data movement to and from AWS.

Purpose of Additional LIFs: Since the AFF A250 is being added to an existing cluster, it will share the cluster's existing infrastructure but will still need its data LIFs configured to participate in cloud tiering.

Best Practices: It's advisable to configure multiple LIFs across different subnets or network paths to ensure redundancy and optimal data flow, especially in a cloud-tiered environment to maintain performance and availability.

For more specific instructions on configuring LIFs for cloud tiering in a NetApp environment, refer to NetApp's technical documentation on cloud tiering and cluster networking: NetApp Cloud Tiering Documentation.
