Enabling Flash Cache on Cloud Volumes ONTAP in AWS

Contributors netapp-bcammett

Some EC2 instance types include local NVMe storage, which Cloud Volumes ONTAP uses as Flash Cache. Flash Cache speeds access to data through real-time intelligent caching of recently read user data and NetApp metadata. It is effective for random read-intensive workloads, including databases, email, and file services.

Note Cache rewarming after a reboot is not supported with Cloud Volumes ONTAP.
Steps

  1. Select one of the following EC2 instance types, which are available with the Premium and BYOL licenses:

    • c5d.4xlarge

    • c5d.9xlarge

    • r5d.2xlarge

  2. Disable compression on all volumes.

    Compression must be disabled on all volumes to take advantage of the Flash Cache performance improvements. You can choose no storage efficiency when creating a volume from Cloud Manager, or you can create a volume and then disable data compression by using the CLI.
