AUE - Key Insights
Good morning/afternoon/evening everyone! This is Rich Barlow, Principal Technologist @ Pure. It was super fun to proctor this AUE session with Antonia and Jon. Hopefully everyone got in all of the questions that they wanted to ask - we had so many that we had to answer many of them out of band. So thank you for your enthusiasm and support. Looking forward to the next one! Here's a rundown of the most interesting and impactful questions we were asked. If you have any more please feel free to reach out. FlashArray File: Your Questions, Our Answers (Ask Us Everything Recap) Our latest "Ask Us Everything" webinar with Pure Storage experts Rich Barlow, Antonia Abu Matar, and Jonathan Carnes was another great session. You came ready with sharp questions, making it clear you're all eager to leverage the simplicity of your FlashArray to ditch the complexity of legacy file storage. Here are some the best shared insights from the session: Unify Everything: Performance By Design You asked about the foundation—and it's a game-changer. No Middleman, Low Latency: Jon Carnes confirmed that FlashArray File isn't a bolt-on solution. Since the file service lands directly on the drives, just like block data, there's effectively "no middle layer." The takeaway? You get the same awesome, low-latency performance for file that you rely on for block workloads. Kill the Data Silos: Antonia Abu Matar emphasized the vision behind FlashArray File: combining block and file on a single, shared storage pool. This isn't just tidy; it means you benefit from global data reduction and unified data services across everything. Scale, Simplicity, and Your Weekends Back The community was focused on escaping the complexities of traditional NAS systems. Always-On File Shares: Worried about redundancy? Jon confirmed that FlashArray File implements an "always-on" version of Continuous Available (CA) shares for SMB3 (in Purity 6.9/6.10). It’s on by default for transparent failover and simple client access. Multi-Server Scale-Up: For customers migrating from legacy vendors and needing lots of "multi-servers," we're on it. Jon let us know that engineering is actively working to significantly raise the current limits (aiming for around 100 in the next Purity release), stressing that Pure increases these limits non-disruptively to ensure stability. NDU—Always and Forever: The best part? No more weekend maintenance marathons. The FlashArray philosophy is a "data in place, non-disruptive upgrade." That applies to both block and file, eliminating the painful data migrations you’re used to. Visibility at Your Fingertips: You can grab real-time IOPS and throughput from the GUI or via APIs. For auditing, file access events are pushed via syslog in native JSON format, which makes integrating with tools like Splunk super easy. Conquering Distance and Bandwidth A tough question came in about supporting 800 ESRI users across remote Canadian sites (Yellowknife, Iqaluit, etc.) with real-time file access despite low bandwidth. Smart Access over Replication: Jon suggested looking at Rapid Replicas (available on FlashBlade File). This isn't full replication; it’s a smart solution that synchronizes metadata across sites and only pulls the full data on demand (pull-on-access). This is key for remote locations because it dramatically cuts down on the constant bandwidth consumption of typical data replication. Ready to Simplify? FlashArray File Services lets you consolidate your infrastructure and get back to solving bigger problems—not babysitting your storage. Start leveraging the power of a truly unified and non-disruptive platform today!

The promise of modern storage is simple: when the system says “yes,” your data better be safe. No matter what happens next; power failure, controller hiccup, or the universe throwing what else it has at you writes need to stay acknowledged. FlashArray is engineered around this non‑negotiable principle. Let me walk you through how we deliver on it. Durable First, Fast Always When your application issues a write to FlashArray, here’s the path it takes: Land in DRAM for inline data reduction (dedupe, compression, you know the lightweight stuff). Persist redundantly in NVRAM (mirrored or RAID‑6/DNVR, depending on platform), in a log accessible by either controller. Acknowledge to the host ← This is the critical moment. Flush to flash media in the background, efficiently and asynchronously. Notice what happens between steps 2 and 3? We don’t acknowledge until data is durably persisted in non‑volatile memory. Not “mostly safe,” not “probably fine” but safe and durable. This isn’t a write‑back cache we’ll get around to flushing later. The acknowledgement means your data survived the critical path and is now protected, period. Power Loss? No Problem. FlashArray NVRAM modules include integrated supercapacitors that provide power hold‑up during unexpected power events. When the power drops, these capacitors ensure the buffered write log is safely preserved without batteries to maintain, no external UPS required just to have write safety. Though it is recommended, no external UPS is necessary for write safety; many sites still deploy UPS for broader data center and facility reasons. Because durability is achieved at the NVRAM layer, we eliminate the most common failure mode in legacy systems: the volatile write cache that promises safety but can’t deliver when it matters most. Simpler Path with Integrated DNVR In our latest architectures, we integrate Distributed NVRAM (DNVR) directly into the DirectFlash Module (DFMD). This simplifies the write path fewer hops, tighter integration, better efficiency. And scales NVRAM bandwidth and capacity with the number of modules. By bringing persistence closer to the media, we’re not just maintaining our durability guarantees we’re increasing capacity and streamlining the data path at the same time. Graceful Under Pressure What happens if write ingress temporarily exceeds what the system can flush to flash? FlashArray applies deterministic backpressure you may see latency increase but I/O is not being dropped. Thus data is not at risk. Background processes yield and lower‑priority internal tasks are throttled to prioritize destage operations, keeping the system stable and predictable. Translation: we slow down gracefully and don't fail unpredictably. High Availability by Design Controllers are stateless, with writes durably persisted in NVRAM accessible by either controller. If one controller faults, the peer automatically takes over, replays any in‑flight operations from the durable log, and resumes service. A brief I/O pause may occur during takeover; platforms are sized so a single controller can handle the full workload afterward to minimize disruption to your applications. No acknowledged data is lost. No manual intervention required. Just continuous operation. Beyond the ACK: Protection on Flash After the destage, data on flash is protected with wide‑striped erasure coding for fast, predictable rebuilds and multi‑device fault tolerance. And NO hot‑spare overhead. The Bottom Line Modern flash gives you incredible performance, but performance means nothing if your data isn't safe. FlashArray's architecture makes durability the first principle—not an optimization, not an add-on, but the foundation everything else is built on. When FlashArray says your write is safe, it's safe. That's not marketing. That's engineering. This approach to write safety is part of Pure's commitment to Better Science, doing things the right way, not the easy way. We didn't just swap drives in an existing architecture; we reimagined the entire system from the ground up, from how we co-design hardware and software with DirectFlash to how we map and manage petabytes of metadata at scale.

Yes, I am going to die on the hill of making Tuesdays a new special day for Pure Storage 😀. For those of you out there who have upgraded Purity within the last two years or so - what was the feature that was added or upgraded that made you say, "WOW"? I'll start - FA Files was my first launch project here so I got a solid peek behind the curtains about all that went into it and was blown away by where the PM team was planning on taking it. What about your experience? Sound off below!Choosing Between Snapshots and Backups? Use Both
Let's settle the old debate: snapshots or backups for data protection? The answer is you need both, working together. The Problem VMware snapshots are great for quick rollbacks, but they create redo logs that strain storage IO and need eventual consolidation. During active snapshots, your storage reads multiple files simultaneously, potentially impacting production. Storage snapshots like Pure's are instantaneous and lightweight, but they capture entire volumes at once, are only crash-consistent, and require full restores or manual workarounds to extract specific data. Neither alone covers every recovery scenario you'll face. The Solution Integrate VMware, Pure Storage, and Veeam into a cohesive platform: Leverage Pure snapshots for fast, efficient data capture without production impact Use Veeam to orchestrate application-consistent backups and enable granular restores Keep snapshots close to the source for quick recovery Maintain backup files for long-term retention Replicate everything to DR sites with the same capabilities The Payoff One integrated solution gives you flexibility for any situation: ransomware recovery from immutable snapshots, granular file restores, site failovers, or long-term archive retrieval. All without impacting production. Modern data protection isn't about picking sides. It's about making your storage, hypervisor, and backup solution work together intelligently.

Happy post-Purity Upgrade Tuesday to everybody! I titled my last post with that concept, and am going to keep pushing it until it becomes a thing 😀. Anyway, with this post, I needed to make a Matrix reference because I am playing into the odds most of us IT geeks in this channel love that movie 🤓. That being said - for those of you out there who have done a recent Purity upgrade, which path did you choose: The Red Pill - The "white glove" service provided by support The Blue Pill - Self Support Upgrade via Pure1 Best part to the choices is neither one is wrong because the both deliver the same result - a updated version of Purity that more than likely has added additional capabilities or even a performance increase. This is the core value of Purity - it is continually being improved for adding value with each new revision, and not just addressing tech debt and bugs. Sounds off here on your experience to let everybody know how it went!It's Purity Upgrade Tuesdays!!! Get Excited!
OK - maybe I made that special event Tuesday thing up, but you have to admit it's catchy in a way every terrible social media feed ad grabs your eye 😀. And with that, it does lead to a great question: Are you on the latest version of Purity? As you may or may not know, we had some recent Purity releases over the summer...we've been busy: Purity 6.9.1 for FlashArray: This is the latest Long Life Release (LLR) Purity 6.10 for FlashArray: This is the latest Feature Release (FR) Purity 4.5.12 for FlashBlade: This is the latest LLR Purity 4.6.2 for FlashBlade: This is the latest FR Click here for a quick reminder on what their difference is in a blog from my buddy Ben Casey, the wisest Puritan I know. 💪 And with that being said - how did your latest upgrade go? Did you use Pure1 or the support white glove service we offer? Give us your stories - good and bad...we are all in learning mode and listening! Just don't expect me to send special Hallmark cards to mark Tuesdays as a special day 😀. Happy upgrading! DP
