15 Architectural Decisions Series: Flash and Data Reduction

Our series around Pure's fundamental design principles continues. Episode 3 discusses three key architectural decisions: stateless controllers, the second controller, and limited error paths. Hear from co-hosts JD Wallace and Andrew Miller about how stateless controllers mean no identity or state is stored within the controller itself, allowing for easy replacement and upgrades without downtime. This design philosophy simplifies maintenance, reduces support costs, and enables seamless technology migrations, allowing Pure customers to upgrade hardware generations without impacting business operations. This is a significant shift from older storage array methods that required complex, time-consuming manual processes and often led to downtime.

We then further explore the strategic decision behind having a second controller in an active-standby configuration, prioritizing consistent performance and uptime over maximizing raw performance from both controllers simultaneously. This approach ensures that performance remains stable even during failovers or planned upgrades, eliminating unpredictable results and reducing the need for constant monitoring by IT admins. By focusing on reliability and simplicity, Pure Storage aims to provide a "cloud-like" experience for on-prem and cloud connected storage, significantly reducing operational complexity and enabling faster adoption of new technologies and features.

Episode 4 of our series around Pure's fundamental design principles dives into aspects of Pure's technology that drive realistic efficiency for users. This episode tackles capabilities most Storage professionals are familiar with - snapshots, efficiency metrics and adaptive flexible RAID.

Pure learned from the challenges created by legacy architectures to build better versions of these features into our all-flash array portfolio. Hear about how Pure Storage’s snapshot architecture focuses on instant, efficient, and immutable copies that serve both operational and security needs. Snapshots can be created instantly with no performance overhead and used for rapid recovery, cloning, or replication—each one functions as a “gold copy version” and maintains group consistency, enabling rollbacks to any point in time without dependencies or data duplication. Their design is tightly integrated with metadata, enabling efficient thin provisioning and consistent protection, while SafeMode extends these benefits by enforcing privileged access and retention policies for ransomware resilience. Around realistic efficiency metrics - we deliver transparent and realistic efficiency metrics by directly reporting space consumption trends and physical storage utilization, rather than relying solely on claims about thin provisioning or data reduction. Our user interface distinguishes between budgeted capacity, usable capacity, and used space, with a focus on showing only live user data (volumes and snapshots), and hiding internal system overhead, RAID overhead, and reclaimable space until critical thresholds are reached. Finally, we tackle RAID - Pure’s RAID architecture is built for flash, utilizing a flexible, adaptive structure that never requires manual configuration while continuously ensuring optimal data protection and performance.

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.

We made it to Episode 6 - the final in our 15 Architectural Decisions series and saved some of the best for last - Predictive and Proactive support (Pure1) combined with our Evergreen architecture and non-disruptive everything. In this episode, JD, Andrew and I dive into Pure Storage's foundational principles that ensure continuous operation and future-proof your storage. We explore the concept of "Non-Disruptive Everything," a core tenet that allows for seamless upgrades and expansions without any downtime. This ties directly into the innovative Evergreen Storage Model, which redefines the ownership experience by eliminating forklift upgrades and enabling independent evolution of performance, capacity, and features over a decade-long array lifecycle.

We also discuss how Pure's proactive and predictive support, powered by Pure1, plays a critical role in maintaining this non-disruptive environment. Pure1's advanced analytics, anomaly detection, and data protection assessments provide unparalleled visibility and ensure that potential issues are identified and addressed before they impact operations. This integrated approach, from architecture to support, highlights how Pure Storage consistently delivers a cloud-like experience on-premises, setting a new standard for reliability and longevity in the storage industry.

Data management in high-performance computing (HPC) and AI environments presents unique challenges, especially with heavy file usage and evolving data lifecycles. This edition of the Pure Report podcast delves into these complexities, exploring how data transitions through development, simulation/training, inference/optimization, and long-term retention phases. Together with Pure technologists Bikash Choudhury and Don Poorman, we’ll tackle the critical problem statement: reducing total cost of ownership (TCO) by automatically moving inactive data to different tiers without sacrificing accessibility or performance during crucial operational stages.

Join us as we introduce Pure Storage's innovative Zero Move Tiering (ZMT) solution. Discover how ZMT delivers dynamic Service Level Agreements (SLAs) across performance and capacity tiers without data movement, leading to lower TCO and zero operational overhead. We'll also examine how ZMT fits into various data lifecycle stages, from development build workloads to AI-augmented modeling and simulation, and compare Pure's approach to the common deficiencies seen in other vendor solutions.
