Manchester, UK, June 03, 2026 (GLOBE NEWSWIRE) — PEAK:AIO, a leader in high-performance storage for artificial intelligence (AI) and high-performance computing (HPC), today announced Lattice, the industry’s first open-source pNFS metadata server. Developed through a long-term engineering collaboration between PEAK:AIO and Los Alamos National Laboratory (LANL), Lattice introduces a new distributed metadata architecture designed to eliminate one of the most persistent constraints in large-scale AI and high-performance computing infrastructure.
The announcement comes as AI infrastructure demands reshape the storage market. AI workloads, including training large models, running inference at scale and serving agentic AI applications, require ultrafast, parallel access to massive datasets continuously and reliably. GPU compute has scaled dramatically, but the storage layer feeding it, and particularly the metadata architecture coordinating it, has not kept pace. Average GPU utilization across 23,000 production clusters is 5% (Cast AI), not because the hardware is inadequate, but because the software feeding it cannot keep up. The metadata bottleneck in parallel storage systems has become a critical constraint on AI workload performance.
Lattice resolves this architectural limitation. Built as a Linux-based, user-space pNFS metadata server designed for scale, modularity and distributed coordination. Open source, community supported and launched under the Linux Foundation, Lattice separates the metadata control plane into four distinct layers: Protocol State Plane, Lattice Core, MD Catalog Authority and Data Server Control Plane. This architecture makes metadata services truly elastic for the first time, allowing them to spin up dynamically on commodity hardware whenever and wherever needed, from a single server to more than 1,000 metadata servers.
The announcement will be formally presented at the International Conference on Massive Storage Systems…
