Eliminate Risk of Failure with Pure Storage FAAA_004 Exam Dumps

To determine the raw capacity required to meet the customer's needs for 3 years, we need to account for the current workload, data reduction ratio (DRR), growth rate, and headroom.

Step-by-Step Calculation:

Current Logical Workload :

The customer's current workload is 50 TB .

Expected Growth Over 3 Years :

The workload grows at a predictable rate of 25% per year .

After 3 years, the logical workload will be:

Pure Storage helps customers increase storage density in their arrays as new technology becomes available through its Evergreen//One subscription program. Here's an analysis of the options:

Analysis of Options:

A . Customers can attach third-party storage arrays to the Pure Storage array :

Pure Storage does not support attaching third-party storage arrays directly to its arrays. This is not a valid option.

B . Customers can leverage Pure Storage's Capacity Consolidation offering :

While capacity consolidation is a benefit of Pure Storage arrays, it does not specifically address increasing storage density with new technology.

C . Customers can mix HDDs and flash modules within the same array :

Pure Storage arrays are all-flash and do not support mixing HDDs and flash modules. This is not a valid option.

D . Customers can add a shelf with an Evergreen//One subscription :

With Evergreen//One , customers can non-disruptively add new shelves or upgrade their arrays to take advantage of newer, denser storage technologies without rebuying existing storage. This is the correct answer.

Recommendation:

The correct answer is D. Customers can add a shelf with an Evergreen//One subscription .

To calculate the minimum storage capacity required to handle the Oracle workload, we need to account for the thick-provisioned storage requirement and the expected data reduction ratio (DRR).

Step-by-Step Calculation:

Logical Storage Requirement :

The application requires 398 TB of thick-provisioned storage from the host.

Data Reduction Ratio (DRR) :

The DRR is 3:1 , meaning the physical storage required is:

Recommendation :

The SE should propose 132 TB of physical storage, as it meets the requirement after accounting for data reduction.

Final Recommendation:

The correct answer is A. 132 TB .

Capacity Planning Guide :

The DirectCompress Accelerator (DCA) is a hardware component introduced in certain FlashArray models to enhance inline data compression performance. To determine the minimally required FlashArray model that includes DCA, let's analyze the options:

Analysis of Options:

A . FlashArray//X70 R4 :

The FlashArray//X70 R4 was the first model to include the DirectCompress Accelerator (DCA).

This makes it the minimally required model for DCA support.

B . FlashArray//X70 R3 :

The FlashArray//X70 R3 does not include the DCA. It relies on software-based compression, which is less efficient than hardware-accelerated compression.

C . FlashArray//X90 R4 :

The FlashArray//X90 R4 includes DCA but is a higher-tier model than the X70 R4. While it supports DCA, it is not the minimal requirement.

D . FlashArray//XL130 :

The FlashArray//XL130 is a high-performance model that includes DCA, but it is overkill for this requirement and not the minimal model.

Recommendation:

The correct answer is A. FlashArray//X70 R4 , as it is the first model to include the DirectCompress Accelerator (DCA).

The customer currently has a FlashArray//X with 40 TB of available block storage and needs to add 10 TB of file workloads while minimizing infrastructure costs. Let's analyze the options:

Analysis of Options:

A . Run both workloads on the current FlashArray :

Pure Storage FlashArray supports both block and file workloads using the Purity File Services feature, which allows customers to run file workloads directly on their FlashArray.

Since the FlashArray already has 40 TB of available storage, adding 10 TB of file workloads is feasible without requiring additional hardware. This is the most cost-effective solution.

B . Add another disk pool for file storage to their current FlashArray :

Adding a separate disk pool for file storage is unnecessary because Purity File Services can handle both block and file workloads on the same array.

C . Purchase an entry-level FlashBlade for the file workload :

While FlashBlade is designed for file and object workloads, purchasing a new FlashBlade would be significantly more expensive than leveraging the existing FlashArray. This option does not align with the customer's goal of minimizing costs.

D . NDU the FlashArray //X to a //XL and run both workloads there :

Upgrading the FlashArray//X to a FlashArray//XL via a Non-Disruptive Upgrade (NDU) is unnecessary for this use case. The current FlashArray//X has sufficient capacity to handle both workloads, and upgrading to a higher-tier array would increase costs unnecessarily.

Recommendation:

The most cost-effective solution is A. Run both workloads on the current FlashArray , leveraging Purity File Services to support the file workload.
