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.

Within RVtools, the "vDisk" tab provides actual utilization information on thick provisioned disks. This tab displays detailed information about the virtual disks, including their size, provisioning type, and utilization metrics. Administrators can use this information to analyze disk usage and plan capacity accordingly.

Problem Analysis:

The customer is facing issues with a mixed vendor environment where updates are slow to release.

WebScale Architecture Facet:

One-click upgrades: A core feature of Nutanix’s WebScale architecture, which allows for seamless and non-disruptive upgrades of the entire infrastructure stack, including hypervisor, firmware, and Nutanix software components.

Explanation:

One-click upgradessimplify the upgrade process by automating and orchestrating the update of various components within the Nutanix environment.

This feature ensures minimal downtime and reduces the complexity associated with managing updates across multiple vendors.

It provides a consistent and streamlined update experience, ensuring that the infrastructure remains current without the operational burden typically associated with multi-vendor environments.

Outcome:

The customer will benefit from a simplified upgrade process, reducing the time and effort required to maintain up-to-date systems.

This feature addresses the core issue of slow update releases from multiple vendors, ensuring that the infrastructure is always running the latest supported versions.
