与其他ONTAP集群相比、一个集群的文件传输吞吐量较低

适用场景

所有版本的ONTAP或Data ONTAP

问题描述

  • 集群中的单个服务器(例如ESX集群的虚拟机管理程序或SQL Server)在运行同一工作负载时吞吐量较慢、并且ONTAP不会显示延迟的问题描述。
  • 这会导致用户或VM出现磁盘I/O问题或性能下降
  • 示例:ddserver1server2以下各项相比、运行时性能较差的吞吐量会下降:
server1:~# dd if=/dev/zero of=/mnt1/path1/testfilegk bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 20.047 s, 53.6 MB/s server2:~# dd if=/dev/zero of=/mnt1/path1/testfilegk bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 2.554 s, 420 MB/s
