Applies to

  • Cloud Volumes ONTAP (CVO)
  • Amazon Web Services (AWS)
  • Non-Volatile Random Access Memory (NVRAM)
  • Boot disk

Description

  • In some rare circumstances customers may want to change the IOPS on the AWS CVO NVRAM disk (can be shared with boot disk).
    • Typically this is only in response to working with the Performance team in NetApp Support or a NetApp architect/Cloud resource.
    • The procedure below only applies to CVO clusters deployed in AWS.

Note: The IOPS on the boot disk can be increased on a running system without any negative impact.

Example: The boot disk is identified by EBS volume mounted on /dev/sda1 to the EC2 instance as shown in the screenshot below.
