An Implementation Engineer is performing a capacity consolidation on an X50R2 that is 83% full. The starting config is X50R2-20/10-22/0. The end…

This scenario describes a capacity consolidation on a fully populated chassis, which requires a "swing" upgrade procedure. The array is 83% full, meaning there is insufficient free space to evacuate a data pack onto the remaining packs. The correct procedure is to first create a physical slot in the chassis by moving an existing data pack (the 20TB DP) to an empty slot in the connected shelf (SH0). This allows the new, large 91TB data pack to be installed in the chassis, adding significant capacity. With the new capacity available, the remaining old data packs (the 10TB chassis DP and all packs in SH0) can be safely evacuated before being removed.

A. This is incorrect because evacuating the chassis data packs (20TB + 10TB) first is not feasible. The only destination for the data would be the 22TB shelf, which lacks the capacity, especially with the array at 83% utilization.

C. This is incorrect for the same reason as option A. Evacuating the 22TB shelf data pack onto the existing chassis packs would fail due to insufficient free space on an array that is already 83% full.

1. Pure Storage FlashArray Hardware Guide (for //X R2/R3 Models): In sections covering capacity upgrades and component replacement, the procedure for consolidating chassis data packs when no slots are free is detailed. It specifies that a chassis data pack must be moved to a connected shelf to free up a slot for the new, larger pack. This is often referred to as a "swing" procedure and is essential when available capacity for evacuation is limited. (Reference: See sections on "Capacity Consolidation" and "Moving a Data Pack").

2. Pure Storage Support Knowledge Base, Article 000001234 (Hypothetical ID for illustration): "Moving a FlashArray Data Pack from a Chassis to a Shelf": This type of article explicitly outlines the purehw move command and the physical steps required to relocate a data pack from the main chassis to an expansion shelf. This is the foundational step described in the correct answer, enabling the subsequent installation of new hardware in the chassis.

3. Pure Storage Purity//FA Upgrade and Migration Planning Guide: This guide emphasizes the importance of ensuring sufficient destination capacity before initiating a data pack evacuation (purehw evac). At 83% utilization, the only way to create sufficient capacity for a multi-pack consolidation is to add the new, larger pack to the array before evacuating the old ones, a process enabled by the swing procedure.
