A distributed file system from DeepSeek that uses SSDs and RDMA networks to serve storage for AI training and inference workloads.

Why you might care

Aimed at teams running large AI clusters who need shared storage with high aggregate throughput, strong consistency via CRAQ, and a standard file interface backed by FoundationDB for metadata. Relevant for dataloaders, parallel checkpointing, and KVCache offload; the README reports a 6.6 TiB/s read test on a 180-node cluster.
