Introducing CoreWeave AI Object Storage
CoreWeave is excited to announce CoreWeave AI Object Storage - a purpose-built object storage solution for storing and loading training code, checkpoints, and model weights.
AI Object Storage efficiently serves data directly to GPU Nodes through an S3-compatible API, and via model serializers such as CoreWeave Tensorizer. AI Object Storage works in tandem with CoreWeave's Local Object Transfer Accelerator (LOTA), a first-of-its-kind, Node-local connection to Object Storage that enables a hyper-efficient path for object data to the GPU, while caching data on GPU Nodes to additionally reduce load times.
CoreWeave AI Object Storage is independent of Cloud provider infrastructure, making it a flexible option for multiple use cases and environments.
Key features
Local Object Transfer Accelerator (LOTA)
CoreWeave's Local Object Transfer Accelerator (LOTA) is an intelligent proxy installed on every GPU Node in a CKS cluster to accelerate data transfer. LOTA achieves this by providing a highly efficient, local gateway to CoreWeave AI Object Storage on each Node in the cluster for faster data transfer rates and decreased latency.
Security and availability
CoreWeave AI Object Storage is designed to safeguard information that requires secure, reliable containment for long periods of time. AI Object Storage offers superior reliability by providing high redundancy, versioning, and bucket security policies.
Zones featuring AI Object Storage
At this time, AI Object Storage is available in the following Zones, and will be available in additional Zones soon:
- RNO2
- US-EAST-02A
- US-EAST-04A
- US-EAST-06A
- US-EAST-08A
