回答

S3 / Swift（keystone環境なし）
- 既存のオブジェクトに対するGET / HEAD要求に関連するAPIはすべて成功します。
- 次の理由により、新しいPUT / Overwrite / Deleteに関連するすべてのAPIが失敗します： Cassandra Driver Error(Unavailable)
Swift（keystone環境を使用）
- の理由により、すべてのAPIが失敗します Token generation CQLquery failed。
  - Swiftでは、少なくとも2つのADCノードがオンラインである必要があります。

追加情報

テナント情報は、キースペースアカウント（tableなど）のCassandraテーブルに保存されます accounts。そのため、Cassandraが影響を受けるとテナントの作成も失敗します。
