Considerations • Transfer performance to the Snowball Edge device depends upon multiple factors including: the size of files being transferred, read performance of the source data storage system, tools used for the data transfer, network link speed, network utilization, network latency, and the number of network hops between the data transfer client and the Snowball Edge unit. Consider these aspects when planning for a Snowball Edge job. • Use AWS Command Line Interface (AWS CLI) with Amazon S3 to improve transfer performance by employing multiple sessions and parallelizing operations when transferring large volumes of data. • To accurately predict the total time required to migrate large datasets to Amazon S3 using Snowball Edge, you must first run benchmarks and measure performance in your own environment. The time to import a job from the Snowball Edge device into Amazon S3 is comparable to the time required to transfer data from on-premises storage systems into the Snowball Edge unit. • Consider the File interface (NFS) when you need to preserve the metadata of files and the performance requirements are low. Use the Amazon S3 interface for performance demanding data transfers. The maximum file size that can be transferred to Snowball Edge using the File interface is 150 GB. • The File interface on Snowball Edge implements a subset of the standard NFS specifications. The File service runs on a separate IP address that must be created using the snowballedge command line tool before enabling it. See Using the File Interface for the AWS Snowball Edge for more information. • After the import job completes, you can review the Snowball job reports from the AWS Management Console. See Verification for more information. Before You Order AWS Snowball Edge is a Region-specific service. Verify that the service is available in your Region before you begin planning your migration. See Regional Table to verify availability. Ensure that your location and bucket are within the same Region or country. The AWS Management Console does not allow device orders if the bucket and Region are not in the same location. Limitations to shipping outside of a Region’s country borders are
