适用场景

  • ONTAP 9
  • ODX (卸载数据传输)

问题解答

  • 在ODX要求中,使用经过压缩的卷时,压缩格式必须为 adaptive
  • 支持的压缩组大小仅为 8K
  • 在FAS系统中、仅 允许执行后处理、并且 application-io-size 参数设置为""not allowed因此,不会进行后台重新压缩,它将保持为 自适应/8K
  • 对于AFF系统,当 application-io-size 参数设置为时 'auto',热数据将使用 8K压缩 组进行实时压缩。然后、使用更主动的 32 K压缩 组在后台重新压缩冷数据。因此,在AFF环境中使用ODX时,必须将其显式设置为 8K,而不是 'auto'
