Data Tiering with Cloud Volumes ONTAP

Reduce your storage costs on AWS or Azure by using block storage as a performance tier and object storage as a capacity tier for infrequently-used data

Data tiering enables you to save costs on AWS or Azure storage by automatically tiering your snapshot data, disaster recovery and backup copies, or infrequently-accessed data to a cheaper object storage tier which can be accessed seamlessly and immediately whenever you need it.

Now you can:

  • Spin snapshot data and backup copies to a cheaper storage tier simply and easily.
  • Push DR data to more cost-effective storage.
  • Automatically identify infrequently-accessed data and send it to the less-expensive object storage.
  • Automatically bring data back to the high-performance tier when needed.

Discover how Cloud Manager makes it easy to push your cold data to Amazon S3 and pull it back to an Amazon EBS performance tier.

How Does it Work?

You can choose the tiering policy when you create or edit a volume in Cloud Manager:

  • Snapshots: When Cloud Volumes ONTAP creates Snapshot copies of read-write volumes (point-in-time copies of file systems), it tiers the Snapshot copies to cost-effective Amazon S3 or Azure Blob storage, freeing up the Amazon EBS or Azure LRS, Premium, or Standard storage performance tier for the data.
  • DR copies: When you replicate a volume to a tiered storage configuration for disaster recovery purposes, all data for the destination volume resides in the Amazon S3 or Azure Blob storage capacity tier. The data automatically moves to the Amazon EBS or Azure LRS or Premium/Standard storage performance tier if you activate the destination volume and access data.
  • Auto-tiering policy: Tier cold data blocks to a capacity tier. Data is considered cold when it has not been accessed for 30 days, or for a time period as defined by the user. If read by random reads, the cold data blocks in the capacity tier become hot and are moved automatically to the performance tier. If read by sequential reads (such as those associated with index and antivirus scans), the cold data blocks remain cold in the capacity tier.

When using Cloud Volumes ONTAP with a tiered storage configuration you should be aware of the following:

  • The performance tier can be Amazon EBS or Azure managed disks.
  • Cloud Volumes ONTAP uses a single Amazon S3 bucket or Azure blob for tiered storage.
  • A system's capacity limit is spread across Amazon EBS and Amazon S3 storage or Azure managed disks and Blob storage, respectively.
  • Thin provisioning must be enabled on volumes that use a tiered storage configuration.
  • Storage tiering is not supported with Cloud Volumes ONTAP Explore.
  • Storage tiering is supported with AWS-managed encryption, Azure Storage Service Encryption.
  • Storage tiering is not supported with Cloud Volumes ONTAP-managed encryption.
  • No additional licensing is required to take advantage of tiered storage with Cloud Volumes ONTAP.
