Free PSC Storage Architecture & Design Questions and Answers

Question 1

What is the purpose of the Purity Operating Environment in Pure Storage systems?

Accepted Answer

Powers data reduction, snapshots, and replication features

Answer

The Purity Operating Environment is the intelligent software layer that powers Pure Storage systems. It is responsible for enabling key data services such as always-on data reduction (deduplication and compression), snapshots, and replication. Purity abstracts the underlying flash hardware, delivering a highly efficient and resilient storage platform.

Question 2

Which of the following best describes the Pure Storage FlashArray architecture?

Accepted Answer

All-flash storage array with always-on data services

Answer

The Pure Storage FlashArray is characterized as an all-flash storage array designed for high performance and reliability. Its architecture integrates always-on data services like deduplication, compression, and snapshots directly into the system. This combination provides a powerful, efficient, and resilient storage solution for enterprise workloads.

Question 3

Which feature helps Pure Storage achieve data reduction?

Accepted Answer

Compression & deduplication

Answer

Pure Storage achieves significant data reduction through the use of compression and deduplication technologies. Deduplication identifies and eliminates redundant data blocks, while compression further reduces the size of the remaining unique data. These processes work continuously and in-line to maximize storage efficiency and lower operational costs.

Question 4

What role do DirectFlash Modules play in Pure Storage architecture?

Accepted Answer

Delivers raw flash to software for maximum efficiency

Answer

DirectFlash Modules (DFMs) are Pure Storage's proprietary flash storage devices that deliver raw flash directly to the Purity software. Unlike traditional SSDs with their own controllers, DFMs allow the Purity operating environment to manage the flash at a granular level. This unique approach maximizes efficiency, performance, and endurance of the flash media.

Question 5

Which protocol is commonly supported by Pure Storage FlashArray for block storage?

Accepted Answer

iSCSI & Fibre Channel

Answer

Pure Storage FlashArray commonly supports industry-standard block storage protocols such as iSCSI and Fibre Channel. These protocols are essential for connecting servers and applications to the storage array, enabling high-performance data access. This broad protocol support ensures compatibility with diverse enterprise IT environments.
