Storage Overview
Bridge integrates with enterprise storage systems to provide tenant-isolated, high-performance storage for GPU workloads. Storage integration encompasses network connectivity, per-tenant isolation, and quota enforcement — all managed through Bridge's storage controller.
Supported Storage Systems
| Storage System | Status |
|---|---|
| VAST Data | Supported |
| DDN (DataDirect Networks) | Supported |
| Vanilla NFS | Supported |
| WEKA | In progress |
Supported Storage Types
| Type | Protocol | Use Case |
|---|---|---|
| Parallel file system | RoCE or RDMA over InfiniBand | High-throughput model training, checkpoint storage |
| S3 object storage | HTTPS over in-band network with external access | Transferring models and datasets in and out of the data center |
Multi-Tenancy and Storage Isolation
Bridge enforces per-tenant storage isolation at two levels:
Storage Vendor Level
Storage vendors (VAST, DDN) expose APIs for defining tenant-level constructs. Bridge's storage controllers call these APIs during tenant creation to configure:
- Per-tenant storage namespace or project
- Tenant storage subnet association
- Storage quota limits per tenant
Network Level
Bridge automates per-tenant storage network isolation on the switch fabric:
- A dedicated per-tenant L2 network is created with VxLAN segments extending to the storage node.
- For storage vendors that support VxLAN, the tenant's storage traffic is encapsulated end-to-end.
- Storage traffic is carried on the Converged Network (North-South fabric), isolated from the compute East-West network.
Storage Network Architecture
The Converged Network integrates storage traffic alongside in-band management and external connectivity. Each tenant receives an isolated storage network segment:
Compute Nodes (Tenant T1) → Leaf Switch (VRF T1-storage) → Storage Node
Compute Nodes (Tenant T2) → Leaf Switch (VRF T2-storage) → Storage Node
BGP EVPN propagates the per-tenant VxLAN mappings across the fabric, ensuring storage access is scoped to the tenant's allocated compute nodes.
Storage Onboarding
During Day 0 setup, the NCP Admin onboards storage systems as part of network discovery:
- Discover storage — Bridge discovers storage nodes via the switch fabric topology (LLDP-based) or manual onboarding.
- Configure storage controller — Bridge connects to the storage vendor API (VAST, DDN) or sets up NFS server parameters.
- Verify storage inventory — Confirm the storage system appears in the Bridge infrastructure view.
Storage tenant configuration (quotas, subnets, isolation) is applied automatically when tenants are created in Day N.
