Air-Gapped Bare-Metal Architecture

For defense, national intelligence, and critical petrochemical facilities, Aarkam can be installed in a 100% air-gapped bare-metal environment with zero external network connectivity.


Installation via Offline Media

  1. Download the cryptographically signed Aarkam Offline Bundle:
    # Bundle includes all container binaries, systemd units, and PKI tools
    sha256sum aarkam-enterprise-bundle-beta.tar.gz.sig
    
  2. Mount the installation media on the bootstrap management host.
  3. Execute the automated air-gapped orchestrator:
    ./aarkam-installer.sh --profile air-gapped --cluster-config /etc/aarkam/cluster.json
    

Internal Raft MON Consensus Without External NTP

In isolated datacenters where public NTP servers are blocked:

  • Aarkam uses local GPS/PTP time synchronizers or internal Raft monotonic epochs (EpochFence).
  • Topology state changes require quorum agreement across an odd number of Coordinator nodes (e.g., 3 or 5 MON nodes).
  • Even during full network partitions, split-brain write corruption is mathematically prevented by Raft quorum rules.
