What PEAK:AIO does
PEAK:AIO is a Manchester-based software company founded in 2021 that builds open-source storage and metadata infrastructure for AI and high-performance computing (HPC) workloads. Its core products — Lattice and PEAK Open pNFS — are open-source parallel NFS (pNFS) metadata servers designed to eliminate metadata bottlenecks that constrain data throughput to GPU clusters. Lattice, co-developed with Los Alamos National Laboratory and hosted under the Linux Foundation, enables elastic metadata scaling from a single server to over 1,000 metadata servers on commodity hardware, with demonstrated performance improvements of 5.7x in raw throughput (70 GB/s to 400 GB/s) and over 300% on metadata-heavy workloads compared with conventional approaches.
The company's business model centers on an open-source core distributed through the Linux Foundation, monetized via commercially supported enterprise subscriptions that include full feature sets, premium support tiers, and SLA-backed deployments. Its target customers are AI infrastructure operators and HPC/research institutions — including the NHS and Los Alamos National Laboratory — that face GPU underutilization and scalability constraints from legacy parallel file systems. PEAK:AIO positions itself against established enterprise storage vendors including Dell, DDN, HPE, NetApp, Pure Storage, VAST Data, and WEKA in the high-performance all-flash storage market. Strategic alliances with Solidigm (storage hardware) and Los Alamos National Laboratory (HPC validation) round out the go-to-market, with direct enterprise sales supplemented by open-source community-driven adoption.

PEAK:AIO product offering
Product offeringCore offering
PEAK:AIO develops open-source parallel NFS (pNFS) metadata server software for AI and high-performance computing storage infrastructure. Its products, Lattice and PEAK Open pNFS, eliminate metadata bottlenecks by enabling elastic scaling from a single metadata server to over 1,000 servers on commodity hardware, supporting exabyte-level deployments. The company monetizes commercially supported enterprise versions with SLAs alongside the open-source core.
Product overview
PEAK:AIO is a Manchester-based AI storage software company offering a platform of open-source, vendor-agnostic metadata server products for AI and HPC environments. The portfolio consists of two core offerings: Lattice (an open-source pNFS metadata server developed with Los Alamos National Laboratory, supporting elastic scaling from one to over 1,000 metadata servers) and PEAK Open pNFS (a fully open-source, vendor-agnostic pNFS metadata server for scalable AI and HPC storage). Both products are launched under the Linux Foundation and are designed to address metadata bottlenecks that constrain GPU utilization in AI clusters.
