Storage Efficiency • WAFL Internals Dedupe, Compress, Compact: How WAFL Squeezes Every Byte Out of Capacity Flash Flash is no longer the exotic performance tier — it’s becoming the default. Which makes the question of how efficiently you use every terabyte of it more important than ever. 🕑 8 min read A personal note: I’m a presales manager at NetApp, but this blog is my own space for sharing what I find genuinely interesting in storage engineering. The views below are mine alone, not an official NetApp position, and not a sales pitch — just one practitioner nerding out on a filesystem. WAFL Deduplication Compression Compaction TSSE AFF/ASA C-Series QLC Flash Every gigabyte of flash you buy today costs more than the equivalent gigabyte of spinning disk, and that gap doesn’t look like it’s c...

While the industry races to catch up on quantum readiness, NetApp customers have been protected since day one — at the layer that matters most: where your data lives. ⏱ 7 min read In a world of evolving cyberattacks, organisations invest millions across layers of infrastructure — networks, compute, identity, endpoints — yet a critical question too often goes unasked: when every other layer fails, where do...

Harvest Speaks: Turning ONTAP Metrics Into Conversations

Storage • Observability • AI Agents Harvest Speaks: Turning ONTAP Metrics Into Conversations How an old open-source workhorse quietly became an AI-ready observability layer — and what that means for the way we work with storage data. ⏰ 6 min read The views expressed here are my own personal opinions, based on publicly available information. They do not represent the views of my employer or any vendor, and should not be taken as official guidance, product roadmap, or endorsement. There's a particular kind of open-source tool that never quite gets the spotlight it deserves. It doesn't have a flashy launch event. It doesn't trend on social media. It just sits there, quietly doing its job, one poller cycle at a time — until one day you realise half your monitoring stack has been leaning on it for years without you thinking twice. For a lot of ONTAP and StorageGRID admins, that tool is NetApp Harvest. And thi...

When on-premises GPU capacity runs dry, organisations burst workloads to the cloud — only to discover their data can't follow. NetApp FlexCache bridges that gap without moving a single byte you don't need. 🕓 7 min read • AI Infrastructure • Hybrid Cloud • NetApp ONTAP The GPU queue problem nobody talks about Enterprise AI adoption is accelerating. Data science teams are running more experiments, training larger models, and processing more inference workloads than ever before. The on-premises infrastructure that was sized for last year's ambitions is now permanently oversubscribed. The result is the GPU queue — that invisible...
