付録B カスタムインターフェイステンプレートの例: 複数のボンディングされたインターフェイス
以下のテンプレートは、/usr/share/openstack-tripleo-heat-templates/network/config/bond-with-vlans/ceph-storage.yaml
をカスタマイズしたバージョンです。バックエンドとフロントエンドのストレージネットワークトラフィックを分離するための複数のボンディングインターフェイスと、両方の接続用の冗長性の機能が含まれています (「Ceph ノード向けの複数のボンディングされたインターフェイスの設定」で説明)。
また、カスタムのボンディングオプションも使用します (「ボンディングモジュールのディレクティブの設定」で説明する 'mode=4 lacp_rate=1'
)。
