适用场景

  • ONTAP 9
  • 加密
  • FabricPool

问题解答

Security
FabricPool可在本地层、云层以及在层间移动数据时通过缆线保持AES-256-GCM加密。

本地层

  • FabricPool支持NetApp存储加密(NSE)、NetApp卷加密(NVE)和NetApp聚合加密(NAE)。
  • 使用FabricPool无需NSE、NVE或NAE。

通过缆线

  • 在本地层和云层之间移动的对象使用AES-256-GCM使用TLS 1.2进行加密。
  • 不支持其他加密模式、例如CCM。在某种程度上、加密会影响连接(延迟)、因为对象存储必须使用CPU周期对数据进行解密。
  • 支持在不使用TLS加密的情况下与对象存储进行通信、但不建议这样做。

云层

  • 移动到云层后、由NVE/NAE加密的所有对象都将保持加密状态。
  • 客户端加密密钥归ONTAP所有。
