Understanding your storage with AWS DataSync Discovery

AWS DataSync Discovery is in preview release for DataSync and is subject to change.

AWS DataSync Discovery helps you accelerate your migration to AWS. With DataSync Discovery, you can do the following:

  • Understand how your on-premises storage is used – DataSync Discovery provides detailed reporting about your storage system resources, including utilization, capacity, and configuration information.

  • Get recommendations about migrating your data to AWS – DataSync Discovery can suggest AWS storage services (such as Amazon FSx for NetApp ONTAP, Amazon EFS, and Amazon FSx for Windows File Server) for your data. Recommendations include a cost estimate and help you understand how to configure a suggested storage service. When you're ready, you can then use DataSync to migrate your data to AWS.

How does DataSync Discovery work?

Learn the key concepts and terminology related to DataSync Discovery.

Agent

An agent is a virtual machine (VM) or Amazon EC2 instance that you deploy and manage. DataSync Discovery uses an agent to access the management interface of your on-premises storage system and report findings to AWS.

For more information, see Create an agent.

Discovery job

You run a discovery job to collect information about your on-premises storage system through the storage system's management interface.

You can run a discovery job between 1 hour and 31 days. You'll get more accurate AWS storage recommendations the longer your discovery job runs.

For more information, see Working with DataSync discovery jobs.

Storage system resource information

DataSync Discovery can give you performance and utilization information about your on-premises storage system's resources. For example, get an idea about how much storage capacity is being used in a specific storage volume compared to how much capacity that you originally provisioned.

You can view this information as it's added and updated by using the following:

For more information, see Storage resource information collected by AWS DataSync Discovery.

AWS storage recommendations

Using the information that it collects about your on-premises storage system's resources, DataSync Discovery recommends AWS storage services to help plan your migration to AWS.

You can view recommendations by using the following:

DataSync Discovery architecture

The following diagram illustrates how DataSync Discovery collects information and provides recommendations for migrating data from an on-premises storage system to AWS.


                The first connection is for communicating with the source storage location. The second connection is for transferring between locations. The third and final connection is with the destination storage location.
Reference Description
1 A DataSync agent connects to your on-premises storage system's management interface (using port 443, for example). You then run a discovery job to collect information about your system.
2 The agent sends the information that it collects to DataSync Discovery.
3 Using the information that it collects, DataSync Discovery recommends AWS storage services that you can migrate your data to.

Data protection

DataSync Discovery stores and manages the data that it collects about your on-premises storage system for up to 60 days. When you remove an on-premises storage system resource from DataSync Discovery, you permanently delete any associated discovery jobs, collected data, and recommendations.

Limitations

  • You can currently use DataSync Discovery only in the US East (N. Virginia) Region (us-east-1).

  • DataSync Discovery only supports public service endpoints at this time.

  • You can add up to 10 storage systems per AWS account and AWS Region.

  • A DataSync agent can access up to four storage systems at a time.
