Question 1

Refer to the exhibit. 

What does the depicted value 77.24 T represent? 

  1. Option A:

    Total useable space

  2. Option B:

    Total raw space on the array

  3. Option C:

    The guaranteed capacity

  4. Option D:

    Total deduplicated space

Show answer and explanation

Correct answer: C

The value 77.24 T in the context of Pure Storage FlashArray represents C . The guaranteed capacity. Detailed Explanation: Guaranteed Capacity is a feature of Pure Storage’s Evergreen subscription model. It reflects the effective capacity Pure Storage commits to the customer based on their typical data reduction ratios (deduplication, compression, and pattern removal). This value is calculated as: Guaranteed Capacity=Physical Raw Capacity×Data Reduction Factor(DRF)Guaranteed Capacity=Physi cal Raw Capacity×Data Reduction Factor (DRF) Pure typically guarantees a minimum DRF (e.g., 3:1 for many workloads), but actual savings often exceed this. Why Not the Other Options? A . Total usable space: This would include the total logical capacity after data reduction and overheads (RAID-HD, metadata), which is usually larger than the guaranteed capacity. B . Total raw space: This refers to the physical capacity of drives (e.g., 100TB raw). The value shown (77.24T) is smaller than raw, so this is incorrect. D . Total deduplicated space: Pure Storage combines dedupe, compression, and pattern removal into a single "data reduction" metric. Deduplication alone is not isolated in capacity reporting. Official Reference: Pure Storage documentation explicitly defines Guaranteed Capacity as the "logical capacity Pure commits to deliver, factoring in data reduction." This aligns with the Evergreen//Foreversubscription model, where customers pay for usable capacity, not raw storage.

Question 2

What causes a disruption to Pure FlashArray stateless controller operations or performance, if there is a single array?

  1. Option A:

    Replacing a controller 10 module

  2. Option B:

    Physically relocating an array

  3. Option C:

    Moving from a SAS- to NVMe-based shelf

  4. Option D:

    Upgrade Purity//FA code

Show answer and explanation

Correct answer: B

Among the listed options, physically relocating an array is the action most likely to cause a disruption to Pure FlashArray stateless controller operations or performance.

Why This Matters:

Physical Relocation:

Moving a FlashArray involves powering down the system, disconnecting cables, and transporting the hardware to a new location. This process inherently disrupts operations and performance until the array is reinstalled and brought back online.

Even with proper planning, physical relocation introduces downtime and potential risks (e.g., hardware damage during transport).

Why Not the Other Options?

A . Replacing a controller I/O module:

FlashArray controllers are designed with redundancy and hot-swappable components. Replacing an I/O module typically does not cause significant disruptions, as the other controller continues to handle operations.

C . Moving from a SAS- to NVMe-based shelf:

Transitioning to NVMe-based shelves is a planned upgrade that does not inherently disrupt operations. The array can continue functioning during the transition, though performance may vary temporarily.

D . Upgrade Purity//FA code:

Upgrading Purity//FA (the operating system for FlashArray) is a non-disruptive process. FlashArray supports rolling upgrades, ensuring continuous availability and performance during the update.

Key Points:

Physical Relocation: Causes unavoidable downtime and operational disruption.

Redundancy and Non-Disruptive Operations: FlashArray is designed to minimize disruptions for tasks like module replacement and software upgrades.

Planning Required: Physical relocation requires careful planning to minimize risks and downtime.
