适用场景

  • ONTAP 9
  • IOM12
  • SAS HBA

问题解答

使用IOM12和SAS3卡时的可用带宽取决于以下几个因素:
 
  • 操作大小
  • I/O类型(读/写)
  • SAS HBA的类型
  • 每个节点的SAS端口数
 
如果操作大小为32 KB、则最大带宽如下所示:
 
使用IOM12和2个SAS3端口的4个磁盘架堆栈—6.8 GB/秒
使用IOM12和4个SAS3端口的4个磁盘架堆栈—13.6 GB/秒
使用IOM12和2个SAS3端口的2个磁盘架堆栈—7.2 Gb/秒
 
 
  • 纯读取或纯写入工作负载处于5.7 GB/秒范围的低端
  • 对于32 KB操作大小、SAS HBA PM8072的吞吐量范围约为5.1 GB/秒- 7.2 GB/秒
