Lessons from a storage engineer’s patent journey

By Sridhar Sabesan, senior director, platform engineering, WD (formerly Western Digital) IndiaInnovation rarely begins with a eureka moment. It starts quietly, with a challenge that keeps showing up at work, something that makes you pause and think, “Why does it have to be this way?”Two decades ago, when I began filing invention disclosures, I was focused on the computer segment. Over time I got caught up in delivery cycles and deadlines, solving today’s problems, not tomorrow’s possibilities. It took a while before I comprehended that innovation is all about having an intent.My mindset shifted at Western Digital, leading a business unit for the India team. This is where I learned that innovation goes beyond products. Rather, it’s a joined journey and an ecosystem of ideas, fostered by initiatives like my company’s Innovation Bazaar, Hackathon and Patent Day. I rediscovered the thrill of having a sense of responsibility for evolving the industry and creating something new.One of the most fascinating challenges I tackled was managing rapid storage capacity growth in large-scale data centres. In this environment, picture data as vehicles moving through a bustling city trying to find a parking space. NVMe-oF (Non-Volatile Memory Express over Fabrics) acts as expressways that let vehicles (information) travel swiftly and directly from one location (server) to the parking (storage). However, not all garages can handle the same amount of traffic. Some fill up quickly, especially in central locations during rush hour (AI workloads), while others still have plenty of space. These garages represent storage drives and large platform storage enclosures.Now, imagine if garages with extra space can automatically share capacity to ease the load! A smart city system signalling to incoming cars, “We have room – come park here!” That is where our idea of ₹floating namespaces’ took birth. Traditionally, the storage section is fixed in size, but workloads fluctuate. Our approach allows unused capacity in one namespace to flex and flow to another that needs it, much like cars automatically getting rerouted to clearer access-controlled roads when traffic builds up.The result? Storage architectures that self-balance capacity. Storage adapts dynamically to demand rather than staying rigidly partitioned.For instance, in a cloud setup that hosts multiple enterprise clients, one customer might suddenly need more storage to train an AI model, while another’s usage drops. Traditionally, the system would need more new drives or manually reconfigure storage. With floating namespaces, the system can automatically repurpose underused capacity, improving efficiency, performance and cost in real time, taking care of different categories of data including secured/mission critical and sensitive data.The idea that complex systems can be made to feel intuitive is the very heart of innovation. It makes me believe that patents are not just technical documents; they are stories of how you think differently. Every patent starts with a simple question, asked by someone who cares enough to find an answer. If you are looking to start your own IP journey, the key is to pay attention to the small frictions – to look at places where work feels needlessly complicated and tackle those through collaboration with likeminded people.In the end, every invention has a story, and every story a moral. The moral of this one is not just your IP, it is also about imagination, intent, and the quiet satisfaction of knowing that what you create today could solve tomorrow’s problems. It will be an interesting journey for the upcoming decade in a generative AI driven world.
