RBK-GX (S3-to-Tape Ingest Gateway)
RBK-GX serves as a high-speed S3-compatible landing front-door and local staging cache (S3-compatible backend) translating random backup writes into physical sequential LTO tape append blocks.

Core Engineering Modules
Decoupled functional kernels managing APIs, protocols, and hardware integrations.
S3-Compatible Target Endpoint
Serves as a drop-in S3 endpoint for backup clients, responding directly to standard REST requests (PUT, GET, DELETE).
Landing Cache Buffer Manager
Allocates SSD space to buffer peak upload speeds from backup clients, preventing traffic backpressure.
S3 Front Door API
Listens for standard AWS S3 API commands, handling SigV4 verification and client upload tunnels.
Landing Cache Spooler
Aggregates random object uploads into local cache directories prior to tape serialization.
RBKPack Tape Writer
Packs object data and metadata blocks into single LTO tapes at maximum sequential drive speed.
SCSI Robotic Changer Core
Communicates via low-level SCSI changer commands to load/unload media cartridges directly.
