Cloud Volumes ONTAP (CVO)

Description

  • Cloud Volumes ONTAP has some architectural differences compared to on-premises FAS/AFF that may lead to the NVlogging component of ONTAP becoming a performance bottleneck
  • Typically this manifests as increased write latency or reduced write throughput
  • This may be observed via the qos statistics volume latency show command, latency shown in the NVRAM column:
