ARC-GX Intelligent Hierarchical Storage Subsystem
ARC-GX acts as a high-density archive tier that dynamically moves idle blocks to sequential tapes while leaving active stubs in ZFS namespaces.

- Total Stubbed Files409,219 stubs
- Active Migration Pool16 worker tasks active
- LTO Robotics Queue0 Pending Recall Jobs
Core Engineering Modules
Decoupled functional kernels managing APIs, protocols, and hardware integrations.
FUSE Transparent Mount Path
Handles real-time filesystem calls, automatically intercepting read requests for cold files and retrieving blocks on-the-fly.
Multi-threaded Run Scheduler
Periodically scans directories against age, size, and metadata policies to queue migration candidates.
Buffer Threshold Trigger
Initiates automatic background transfers to tape storage once primary NVMe pool utilization exceeds 90%.
SCSI Tape Robotics Pipeline
Sends native SCSI commands directly to physical tape library changers to manage robotic arm movements and cart loads.
Checksum Loop Scanner
Runs weekly background block audits, validating bit-level parity across ZFS pools and physical LTO tape archives.
Cluster Failover VIP Manager
Coordinates active-active nodes to ensure virtual IP leases instantly migrate if a cluster member experiences a fault.
Encrypted Transport Controller
Secures storage-to-storage replication fabric tunnels using hardware-accelerated TLS 1.3 cryptographic layers.
Off-grid License Monitor
Validates host-bound hardware tokens offline, allowing air-gapped deployments in security-sensitive military or enterprise enclaves.
