Storage Array Architecture
The parallel storage systems that hold petabyte pulse histories and feed high-bandwidth reads to Monte Carlo and training jobs.
Storage as a compute resource
At L0 scale, storage is not passive; it is a performance resource. Monte Carlo campaigns write large tallies, training jobs stream shards continuously, and refinement studies replay old pulses at speed. The storage array architecture is designed for parallel high-bandwidth access, because a starved storage system throttles the compute it feeds.
Parallel and tiered
The archive uses a parallel file system striping data across many devices so that many nodes can read and write concurrently at aggregate bandwidth no single device could reach. Fast NVMe scratch sits close to compute for active jobs, while the bulk archive holds the full petabyte history on higher-capacity media, connected by the escalation and staging logic.
- Parallel file system striped for aggregate bandwidth
- NVMe scratch near compute for active jobs
- Bulk capacity tier for the full pulse archive
- Redundancy and integrity checking across devices
Matching storage to workload
Different L0 workloads stress storage differently. Monte Carlo is write-heavy at the end of each batch; training is read-heavy and streaming; replay is random-access into the archive. The architecture provides staging so that the data a job needs is moved to fast media before the job runs, keeping expensive compute from waiting on slow reads.
Integrity is built in. Data is checksummed and redundantly stored, so a device failure never corrupts a pulse record or a certified simulation result. Given that the archive is the ground truth for all retraining, silent corruption would be worse than loss; the architecture is designed to detect and repair it.
One storage foundation serves both machines and all workload classes. Breeder neutronics tallies, burner stability scans, and twin residual logs all live in the same tiered, parallel, integrity-checked system, staged to fast media on demand. Storage is the quiet substrate beneath every other L0 capability.
