“The long run is already right here,” science fiction author William Gibson as soon as mentioned. “It’s simply not evenly distributed but.” One one that’s trying to carry knowledge storage into the longer term and make it broadly distributed is David Flynn, who’s the CEO and founding father of Hammerspace in addition to a BigDATAwire Individual to Look ahead to 2025.
Even earlier than founding Hammerspace in 2018, Flynn had an eventful profession in IT, together with growing solid-state knowledge storage platforms at Fusion-iO and dealing with Linux-based HPC methods. However now as Hammerspace features traction, Flynn is keen to construct the subsequent technology of distributed file methods and hopefully clear up among the hardest knowledge issues on the earth.
Right here’s our latest dialog with Flynn:
BigDATAwire: First, congratulations in your choice as a 2025 BigDATAwire Individual to Watch! Earlier than Hammerspace, you have been the CEO and founding father of Fusion-io, which SanDisk purchased in 2014. Earlier than that, you have been chief architect at Linux Networx, the place you designed a number of of the world’s largest supercomputers. How did these experiences lead you to discovered Hammerspace in 2018?
David Flynn: It’s a extremely attention-grabbing trajectory, I feel, that led to the creation of Hammerspace. Early on in my profession, I used to be embedding alternate open-source software program like Linux into tiny methods like TV set-top bins, company sensible terminals and the like. After which I got here to design most of the world’s largest supercomputers within the high-performance computing trade that leveraged applied sciences like Linux clustering, InfiniBand, RDMA-based applied sciences.
These two extremes – small embedded methods versus huge supercomputers – may not appear to have a ton in widespread, however they share the necessity to extract absolutely the most efficiency from the {hardware}.
This led to the creation of Fusion-io, which pioneered using flash for enterprise utility acceleration, which till that time was typically used for embedded methods in shopper electronics — for instance, the flash on gadgets like iPods and early cell telephones. I noticed a possibility to take that innovation from the buyer electronics world and translate into the info middle, which created a shift away from mechanical laborious drives in the direction of solid-state storage. The problem then grew to become that this transition in the direction of solid-state drives wanted extraordinarily quick efficiency; the info wanted to be bodily distributed throughout a set of servers or throughout third social gathering storage methods.
The introduction of ultra-high-performance flash was instrumental in addressing this problem of decentralized knowledge, and abstracting knowledge from the underlying infrastructure. Most knowledge in enterprises as we speak is unstructured, and it’s laborious for these organizations to search out and extract the worth inside it.
This realization in the end led to the creation of Hammerspace, with the imaginative and prescient to make all enterprise knowledge globally accessible, helpful, and indispensable, fully eliminating knowledge entry delays for AI and high-performance computing.
BDW: We’re 20 years into the Huge Information growth now, however it feels as if we’re at an inflection level on the subject of storage. What do you see as the primary drivers this time round, and the way is Hammerspace positioned to capitalize on them?
DF: To essentially thrive on this subsequent knowledge cycle, we’ve obtained to repair the damaged relationship between the info and the info infrastructure the place it’s saved. Enterprises must suppose past storage and moderately how they’ll rework knowledge entry and administration in trendy AI environments.
Distributors are all competing to supply the efficiency and scale that’s wanted to help AI workloads. Besides it’s not nearly accelerating knowledge throughput to GPU servers – the core drawback is that knowledge pathways between exterior storage and GPU servers get bottlenecked by pointless and inefficient hops within the knowledge path inside the server node and on the community, whatever the exterior shared storage in use.
The answer right here, which is addressed by Hammerspace’s Tier 0, is using the native NVMe storage which is already included inside GPU servers to speed up AI workloads and enhance GPU utilization. By leveraging the prevailing infrastructure and built-in Linux capabilities, we’re eradicating that bottleneck with out including complexity.
We do that by leveraging the intelligence that’s constructed into the Linux kernel which permits our clients to make the most of the prevailing storage infrastructure they’re already utilizing, with out proprietary shopper software program or different level options. That is along with offering international multi-protocol file/object entry, knowledge orchestration, knowledge safety, and knowledge companies throughout a worldwide namespace.
BDW: You acknowledged on the HPC + AI on Wall Road 2023 occasion that we have been all duped by S3 and object storage to surrender the advantages of native entry inherent with NFS. Isn’t the battle towards S3 and object storage destined to fail, or do you see a resurgence in NFS?
DF: Let’s be clear—its not about object or file, nor, S3 or NFS. Storage interfaces wanted to evolve to perform scale. S3 happened and have become the default for cloud-scale storage for purpose: older variations of NFS merely couldn’t scale or carry out on the ranges wanted for early HPC and AI workloads.
However that was then. At present, NFSv4.2 with pNFS is a special animal—absolutely matured, built-in into the Linux kernel, and able to delivering huge scale and native efficiency with out proprietary purchasers or advanced overhead. In reality, it’s turn into a typical for organizations that demand excessive efficiency and environment friendly entry throughout giant, distributed environments.
So this isn’t about selecting sides in a file vs. object debate. That framing is outdated. The true breakthrough is enabling each file and object entry inside a single, standards-based knowledge platform—the place knowledge will be orchestrated, accessed natively, and served by whichever interface a given utility or AI mannequin requires.
S3 isn’t going away—many apps are written for it. However it’s now not the one choice for scalable knowledge entry. With the rise of clever knowledge orchestration, Tier 0 storage, and trendy file protocols like pNFS, we are able to now ship efficiency and suppleness with out forcing a selection between paradigms.
The long run isn’t about preventing S3—it’s about transcending the bounds of each file and object storage with a unified knowledge layer that speaks each languages natively, and places the info the place it must be, when it must be there.
BDW: How do you see the AI revolution of the 2020s impacting the earlier decade’s large advance, which was separating compute and storage? Can we afford to carry large GPU compute to the info, or are we destined to return to shifting knowledge to compute?
DF: The separation of compute and storage made sense when bandwidth was low-cost, workloads have been batch-oriented, and efficiency wasn’t tied to GPU utilization. However within the AI period, the place idle GPUs imply wasted {dollars} and misplaced alternatives, that mannequin is beginning to crack.
The problem now isn’t nearly the place the compute or knowledge lives—it’s about how briskly and intelligently you may bridge the 2. At Hammerspace, we consider the reply is to not return to outdated habits, however to evolve past inflexible infrastructure with a worldwide, clever knowledge layer.
We make all knowledge seen and accessible in a worldwide file system—regardless of the place it bodily resides. Whether or not your utility speaks S3, SMB, or NFS (together with trendy pNFS), the info seems native. And that’s the place the magic occurs: our metadata-driven orchestration engine can transfer knowledge with excessive granularity—file by file—to the place the compute is, with out disrupting entry or requiring rewrites.
So the true reply isn’t selecting between shifting compute to knowledge or vice versa. The true reply is dynamic, policy-driven orchestration that locations knowledge precisely the place it must be, simply in time, throughout any storage infrastructure, so AI and HPC workloads keep fed, quick, and environment friendly.
The AI revolution doesn’t undo the separation of compute and storage—it calls for we unify them with orchestration that’s smarter than both alone.
BDW: What are you able to inform us about your self exterior of the skilled sphere – distinctive hobbies, favourite locations, and so forth.? Is there something about you that your colleagues is likely to be stunned to be taught?
DF: Exterior of labor, I spend as a lot time as I can with my children and household—normally on skis or dust bikes. There’s nothing higher than getting out on a mountain or a path and simply having fun with the trip. It’s quick, technical, and somewhat chaotic—just about my superb weekend.
That mentioned, I’ve by no means actually separated work from play within the conventional sense. For me, writing software program and inventing new methods to resolve powerful issues is what I’ve all the time cherished to do. I’ve been constructing methods since I used to be a child, and that curiosity by no means actually went away. Even once I’m off the clock, I’m typically deep in code or sketching out the subsequent concept.
Individuals is likely to be stunned to be taught that I genuinely benefit from the inventive course of behind tech—whether or not that’s low-level system design or rethinking how infrastructure ought to work within the AI period. Some people unwind with hobbies. I unwind by fixing laborious issues.
