WS7000 · for the AI compute center
A disaggregated all-flash storage acceleration platform for AI centers / AI factories. Figures below are vendor spec, blueprinted from the GP7000 white paper.
WS7000 adopts a disaggregated architecture in the NVIDIA G3 ICMS lineage with end-to-end NVMe, GPU-direct acceleration and Active-Active HA — for large-model training, long-context inference and agent workflows.
Why storage?
More GPUs deliver diminishing returns. The real bottleneck is data supply: model loading, checkpoint I/O and KV-cache scheduling.
- ✓Cut KV-cache-related cost by ~74% (measured)
- ✓No changes to your training / inference framework
- ✓Independently scale compute and capacity; pool and share
- ✓Deeply adapted to domestic accelerators, self-controlled
Four certainties
From concept to maturity — certainty grounded in verifiable facts.
