A prospect provides sizing details for a new application that will require 15TiB of usable...

To determine the best configuration, we need to calculate the required storage, including the additional 20% growth and the capacity to re-protect in the event of a node failure:

Initial Storage Requirement:

Usable storage required: 15 TiB

Additional storage for 20% growth: 15×0.2=3 TiB15 \times 0.2 = 3 \text{ TiB}15×0.2=3 TiB

Total storage required: 15+3=18 TiB15 + 3 = 18 \text{ TiB}15+3=18 TiB

Storage with Re-protection:

To ensure data protection and availability, Nutanix typically uses a replication factor (RF) of 2, meaning each piece of data is stored twice.

Therefore, the total raw storage needed: 18 TiB×2=36 TiB18 \text{ TiB} \times 2 = 36 \text{ TiB}18 TiB×2=36 TiB

Given these calculations, we should look for a configuration that provides at least 36 TiB of raw storage. Based on typical Nutanix node configurations, Option D provides the best balance of cost and capacity, ensuring that the requirement for 36 TiB of raw storage is met.
