15 Architectural Decisions Series: Encryption, Metadata, and Install/Repair/Replace (DIY)

Episode 5 of our series covers always-on encryption, the smart use of metadata, and our DIY install/repair/upgrade approach. Pure's approach to security is to have it built-in and non-optional, with end-to-end encryption—covering both user data and metadata—using device or software-based AES-256 alongside features like Rapid Data Locking, role-based access controls, and secure erasure methods to protect against breaches and support compliance needs. Next, hear about how metadata serves as the “secret sauce” for Pure, enabling highly efficient, granular data services and powering capabilities like snapshots and instant cloning through a scalable, multi-tiered framework that writes, caches, and protects metadata in ways traditional arrays cannot match. Finally, we touch on installation, repairs, and upgrades which are designed for ultimate simplicity and DIY ease, with non-disruptive software and hardware changes—thanks to Pure’s Evergreen architecture—which allows organizations to grow and evolve storage resources without operational downtime, complex migrations, or compromise. These architectural choices underpin Pure’s promise of secure, resilient, and agile storage that adapts to changing business needs while remaining effortless to manage. Series Overview: Pure Storage’s foundational approach to product engineering is guided by 15 architectural decisions that were established at the company’s inception and have shaped both the technical and user experience across its product lines. These architectural choices were not made arbitrarily—they stem from a deliberate focus on simplicity, efficiency, and scalability, ensuring Pure could deliver storage solutions that break away from legacy complexity and enable continuous innovation without compromise. This series will guide viewers through all of the 15 principles, helping you understand why certain choices were made, how they impact your operations, and how they compare to other industry features and products.
