Step 1: Choose your migration details - AWS Snowball Edge Developer Guide

Step 1: Choose your migration details

Note

A large data migration plan is available for data migrations larger than 500 TB. Create job orders individually on Snow Family devices for your data transfer projects that are less than 500 TB. For more information, see Creating a job to order a Snow Family device in this guide.

  1. Sign in to the AWS Snow Family Management Console. If this is your first time using the AWS Snow Family Management Console in this AWS Region, you see the AWS Snow Family page. Otherwise, you see the list of existing jobs.

  2. If this is your first data migration plan, choose Create your large data migration plan from the main page. Otherwise, choose Large data migration plan. Choose Create data migration plan to open the plan creation wizard.

  3. In Name your data migration plan, provide a Data migration plan name. The plan name can have up to 64 characters. Valid characters are A-Z, a-z, 0-9, and . - (hyphen). A plan name must not start with aws:.

  4. For Total data to be migrated to AWS, enter the amount of data that you want to migrate to AWS.

  5. In Snow devices, choose a Snow Family device.

    Note

    Supported device options might vary based on device availability in certain AWS Regions.

    
                            Example showing device options and configuration.
  6. For Concurrent devices, enter the number of Snow Family devices to which you can simultaneously copy data at your location. If you're not sure, skip to the next section for information about using the concurrent devices estimator wizard to determine this.

  7. Choose Next.

Using the concurrent devices estimator wizard

The concurrent devices estimator wizard helps you to determine the number of concurrent devices that you can use during large data migrations.

Prerequisites:

  • You performed a proof of concept to test your data transfer methodology and measured performance with a Snow Family device in your environment.

  • You know about the network and connection to back-end storage.

Step 1: Enter data source information

First, determine the maximum theoretical throughput for copying data from your storage source.

  1. For Total data to be migrated, enter the amount of data that you plan to migrate.

    For Unit, choose the unit of measurement (GB or TB) for the amount of data you plan to migrate.

  2. For Number of active network interfaces, enter the number of active network interfaces that you have available for data migration from the storage source.

    
                                    The Number of active network interfaces field showing
                                        the default entry of 1.
  3. For Network interface speed, choose the speed of the network interface for the storage source. Network speeds are in Gb/s.

    
                                    Network interface speed showing the default speed of 10
                                        Gb/s.
  4. For Maximum network throughput, enter the maximum tested network throughput to your storage source that you determined during the proof of concept. Throughput is in MB/S.

    
                                    Maximum network throughput, which is blank by
                                        default.
  5. For Storage backend network usage, indicate whether the storage source shares a network with the back-end storage.

    • Choose Yes if the network is not shared. You don't need to enter the speed of the storage interconnection for a single stream.

    • Choose No if the network is shared. Enter the speed of the storage interconnection for a single stream in MB/s.

    Based on your choice, the wizard updates the Max migration throughput for the data source (MB/s) value at the bottom of the page.

    
                                    Storage back-end network usage showing the default value
                                        of yes.
  6. Choose Next.

Step 2: Input migration workstation parameters

You can connect yourSnow Family devices directly to your storage source (a Microsoft Windows server, for example). You might choose instead to connect yourSnow Family devices to one or more workstations to copy data from the storage source.

  1. For Migration workstation usage, indicate your workstation usage choice.

    • Choose None - Use data source directly to transfer data directly from a data source without using a workstation, and then choose Next.

    • Choose Other - Use copy workstation(s) to use one or more workstations for transferring data.

    
                                    Migration workstation usage showing the default value of
                                        Other - Use copy workstation(s).
  2. For Number of active network interfaces, enter the number of ports to use for data migration.

    Number of active network interfaces showing default value of 1.
  3. For Network interface speed, choose the speed in Gb/s of the network interfaces.

    
                                    Network interface speed showing the default value of
                                        10.
  4. In Storage backend network usage, indicate whether the network that the workstations are on is shared with back-end storage.

    • Choose Yes if it's shared.

    • Choose No if it's not shared. Enter the speed of the storage interconnection for a single stream in MB/s.

    
                                    Storage backed network usage showing default value of
                                        yes.

Based on your input, the wizard displays a recommendation in Number of migration workstations. You can manually change the number if you disagree with the recommendation. This number will appear in Concurrent devices in the large data migration plan.


                            Number of migration workstations showing default entry of
                                0.

Step 3: Input average transfer throughput of Snow Family devices

  1. In the Average Snow device transfer throughput field, enter the transfer throughput in MB/s that you saw during your proof of concept.

    
                                    Average Snow device transfer throughput, which is blank
                                        by default

    Based on your average throughput, the wizard updates the Recommended number of concurrent Snow devices and Maximum number of concurrent devices in the migration plan details.

  2. Choose Use this number to continue and return to choosing your migration details. Choose Next and go the next step (Step 2: Choose your shipping, security, and notification preferences).

Note

You can use up to 5 concurrent Snow devices.
