To address the performance concerns of a prospective customer evaluating a hybrid configuration versus an all-flash array, the following Nutanix features should be discussed:

Data Locality:

Nutanix ensures that data is kept local to the node where the VM is running. This reduces latency and increases performance by minimizing the distance data must travel over the network.

Automatic Data Tiering:

Nutanix can automatically move frequently accessed data to faster storage tiers (e.g., SSDs) and less frequently accessed data to slower storage tiers (e.g., HDDs). This ensures that critical data gets the performance benefits of faster storage without the need for an entirely all-flash array.
