适用场景

  • ONTAP 9
  • SMB
  • SMB 签名

问题解答

  • 当 SMB 会话使用 SMB 签名时,与 Windows 客户端之间的所有 SMB 通信都会受到性能影响,从而影响客户端和服务器(即运行包含 SMB 服务器的 SVM 的集群上的节点)
  • 性能影响显示为客户端和服务器上的 CPU 利用率增加,但网络流量不会改变

追加信息

  • SMB 签名可能会干扰某些解决方案,这些解决方案在设计上(例如 WAN 加速器)充当中间人并修改 SMB 网络流量
  • SMB 签名的性能影响
  • 如果对性能的影响太大,请考虑从 ONTAP 9.7 开始为启用了 AES-NI 的存储系统启用 SMB 3 加密。
