A customer requires a service level for an SMB application on Azure NetApp Files with 2TB storage and 200MiB per second throughput. Which service level is suitable?

In the context of Azure NetApp Files, different service levels are tailored to meet varying performance needs and workloads. When considering the requirements of 2TB storage and 200MiB per second throughput for an SMB application, the Ultra service level stands out as the most suitable option.

The Ultra service level is specifically designed to handle high-performance workloads, offering the highest throughput and lowest latency. This level supports throughput capabilities that can satisfy the demands of more intensive applications, making it ideal for scenarios that require rapid data access and high-speed data processing. By opting for the Ultra service level, the customer ensures that the application will perform optimally, leveraging the available bandwidth efficiently.

Other service levels, such as Premium, Standard, and Extreme, have distinct performance characteristics that may not align with the customer's requirements for high throughput and storage. While these levels meet various needs, they do not provide the same level of performance and could result in bottlenecks or less effective resource utilization for the specific 200MiB per second throughput demand of the SMB application. Therefore, selecting the Ultra service level directly addresses the performance requirements needed for proper application functionality.
