适用场景

  • 集群模式 Data ONTAP
  • ONTAP 9

问题解答

是,由于以下原因:

  • 在 7200 RPM 串行 ATA ( SATA )硬盘上使用 ADP 可能会对性能产生负面影响。
  • 首先, SATA 驱动器的性能容量非常有限, ADP 会进一步减少这一问题。
  • 根据系统遇到的磁盘 I/O , SAS 驱动器也可能会出现一些延迟问题。
  • 超过性能容量时,通常会出现额外的延迟。
  • ADP 会延长磁盘重建时间的运行时间。

追加信息

创建高级驱动器分区是为了更高效地使用固态驱动器( SSD )性能容量,方法是将 SSD " 分割 " 到多个分区中,从而使多个聚合能够利用 SSD 提供的大量性能容量。
