Excelero

  • NVMesh2はNVMeshにMesh Network, Mesh Protect, Mesh Inspectが追加されたもの?、既存の機能に何か変更点があるか?
  • Exceleroは複数のノードに同じデータを記録して障害時に切替できるようにしているとのことだが、障害時に別ノードからデータを取得するのはどのような方法を利用するのか?
    • クライアント自身が判断するのか
    • メタデータサーバのようなデーモンにクライアントが問い合わせをして、サーバが故障ノード以外の場所を指示する
  • Exceleroは技術的にRDMA対応のクラウド、Azure(RoCE)やAWS(EFA)で動作する?
  • 技術的課題があるとしたらどのようなことか?
  • Exceleroは、Linux上でデーモンのようなものが動作しているとのことだが、NVMeOFを処理するデーモンが動作しているイメージ?
