适用场景

  • ONTAP 9
  • NFS

问题解答

  • 新挂载不会受到影响、将接收的 最大操作大小tcp-max-xfer-size
  • 现有挂载不会受到影响、除非客户端 再次请求此信息(通常仅在挂载时执行
  • 传输大小越大、通信数量越少、预计这将减轻RTT的影响。
  • 预计RPC调用数量将减少、从而导致CPU负载减少。
  • 预计它适用于大型文件。
  • 如果网络的任何部分不支持较大的传输大小、则可能会发生碎片化、从而导致延迟增加。
  • 如果出现传输错误、可能需要重新传输较大的大小、从而导致不必要的传输量增加、从而对网络带宽产生负面影响。
  • 执行大型传输会占用更多内存或缓冲区。

追加信息

ONTAP NFS 传输大小

警告

  • 由于各种操作系统的行为、NetApp建议不要将ONTAP上允许的最大传输大小减小到低于当前挂载的NFS文件系统的rsize/wsize值
  • 在某些操作系统中、这可能会导致挂起甚至数据损坏
