The exhibit from the Pure1 management interface displays the FlashArray's capacity utilization and forecast. The graph clearly shows a projection that the array will be "Full in 3 months." The current usage is 125.0 TB out of a total 137.4 TB, which is over 90% utilization. This data indicates an imminent capacity shortage. The most direct and appropriate action to resolve this issue is to increase the array's physical storage capacity. This is achieved by adding an expansion shelf containing NVMe DirectFlash modules.

A. Upgrading the controller primarily enhances performance (IOPS, latency) and connectivity, not raw capacity. The exhibit shows a capacity issue, not a performance bottleneck.

C. Adding more network ports would increase host connectivity bandwidth. The problem identified in the exhibit is related to storage space, not network throughput.

1. Pure Storage, "Pure1: Introduction and Administration" Courseware. Module: "Pure1 Assess". This official training material details how the Pure1 capacity forecast uses historical data and AI/ML to predict when an array will reach full capacity, enabling proactive planning for capacity expansion. The "Full in X months" alert is a primary indicator for adding more storage.

2. Pure Storage, "FlashArray//X Hardware Installation and Upgrade Guide," Document Rev H. Section: "Install an Expansion Shelf." This document outlines the physical procedure for expanding a FlashArray's capacity. It states, "You can add expansion shelves to a FlashArray chassis to increase storage capacity." This confirms that adding a shelf is the standard method for capacity augmentation.

3. Pure Storage, "FlashArray Architecture White Paper." Section: "Scale-up and Scale-out." The paper distinguishes between scaling performance and scaling capacity. It explains that performance is scaled by upgrading controllers, while capacity is scaled independently by adding DirectFlash Shelves. The scenario presented is a clear case for scaling capacity.
