适用场景

  • ONTAP 9
  • ONTAP Select  

问题描述

Smtape 用于复制无法通过 WAN 发送的数据。通过 Smtape ,您可以在磁带上传播初始 SnapMirror 传输,然后利用 WAN 建立 SnapMirror 关系,以便将来进行更新。

重要注意事项
  • 只有磁带才支持使用SMTape进行磁带传播。 
  • 当smTape数据流定向到磁盘时、 基线副本的写入速 率最高为5 MB/秒
  • 5 MB/秒比 大多数WAN连接都要慢  
  • 如果速度为5 MB/秒、则10 TB 至少需要23天才能完成传输
  • 因此    ,建议不要使用-file-path选项来替代通过WAN传输SnapMirror数据 ,也 不支持使用此选项。
