Question
A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment. What are two ways to address this problem? (Choose two.)
Options
- AUse Selective LUN Mapping.
- BReconfigure the fabric switch zoning.
- CHave the database team change their backup and recovery schedules for the database.
- DReconfigure the ALUA settings.

Explanation
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can: Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations. Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I/O operations and performance degradation.
