<li>In a data center, hundreds of thousands of GPUs need constant shared access to training data, checkpoints, embeddings, model outputs, and agent memory, pushing AI labs (xAI), neoclouds (CoreWeave, Lambda, Crusoe), and hyperscalers (Microsoft, Google) toward VAST Data’s separated compute/shared flash architecture—which maps well to GPU clusters with many machines reading and writing to one data pool—versus high-speed storage systems designed for supercomputing (Weka, DDN) and reliable storage for basic IT (Pure, Dell, NetApp).</li>

<li>The upside opportunity is to serve as the unifying AI software operating system that powers the infrastructure layer of NVIDIA CEO Jensen Huang’s AI five-layer cake, abstracting away the GPUs &amp; hardware underneath for the developers building models &amp; applications above, expanding the market from model companies &amp; neoclouds into the long tail of enterprises building their own secure, access-controlled agentic applications.</li>
