Azure Data Box Disk: Frequently Asked Questions

Azure Data Box service is designed for offline data ingestion. This service manages an array of products all tailored for data transport for differing storage capacities.

The Azure Data Box Disks allow a quick, inexpensive, and secure transfer of terabytes of data into and out of Azure. Microsoft ships you 1 to 5 disks, with a maximum storage capacity of 35 TB. You can easily configure, connect, and unlock these disks via the Data Box service in Azure portal.

Disks are encrypted using Microsoft BitLocker drive encryption, and your encryption keys are managed on the Azure portal. You then copy the data from the customer's servers. In the datacenter, Microsoft migrates your data from drive to cloud using a fast, private network upload link and uploads it to Azure.

If you have 40 TB of data (or less) that you want to transfer to Azure, you would benefit from using Data Box Disks.

For information on the price of Data Box Disks, go to Pricing page.

To get Azure Data Box Disks, sign in to the Azure portal and create a Data Box order for disks. Provide your contact information and notification details. Once you place an order, based on the availability, disks are shipped to you within 10 days.

For five disks, each with 8-TB capacity (7 TB of usable capacity), the maximum usable capacity is 35 TB. So you can transfer 35 TB of data in one instance. To transfer more data, you need to order more disks.

To see where the Data Box Disks are currently available, go to the Region availability.

Data Box Disk is supported for all regions within US, Canada, EU, UK, Australia, Singapore, India, China, Hong Kong Special Administrative Region, Japan, Korea, and South Africa. Only the Azure public cloud regions are supported. The Azure Government or other sovereign clouds aren't supported.

Data Box Disk supports data ingestion only within the same country/region as their destination and won't cross any international borders. The only exception is for orders in the European Union (EU), where Data Box Disks can ship to and from any EU country or region.

For example, if you wanted to move data at your location in Canada to an Azure West US storage account, then you could achieve it in the following way:

Option 1:

Ship a supported disk containing data using the Azure Import/Export service from the source location in Canada to the Azure West US datacenter.

Option 2:

1. Order Data Box Disk in Canada by choosing a storage account say in Canada Central. SSD disks are shipped from the Azure datacenter in Canada Central to the shipping address (in Canada) provided during order creation.

2. After the data from your on-premises server is copied to the disks, return them to the Azure datacenter in Canada using Microsoft provided return labels. The data present on Data Box Disks then get uploaded to the destination storage account in the Canada Azure region chosen during order creation.

3. You can then use a tool like AzCopy to copy the data to a storage account in West US. This step incurs standard storage and bandwidth charges that aren't included in the Data Box Disk billing.

No. Data Box Disk doesn't store any customer data outside of the service region. The customer has full ownership of their data and can save the data to a specified location based on the storage account they select during the order creation.

In addition to the customer data, there's Data Box Disk data that includes metadata and monitoring logs. In all the regions (except Brazil South, Southeast Asia, and East Asia), Data Box Disk data is stored and replicated in a paired region via a Geo-redundant Storage account to protect against data loss.

Due to data residency requirements in Brazil South, Southeast Asia, and East Asia, Data Box Disk data is stored in a Zone-redundant Storage (ZRS) account so that it's contained in a single region. For Southeast Asia, all the Data Box Disk data is stored in Singapore. For Brazil South, the data is stored in Brazil. For East Asia, the data is stored in Hong Kong.

If there's a service outage in Brazil South, Southeast Asia, or East Asia, the customers can create new orders from another region. The new orders are served from the region in which they're created and the customers are responsible for the to and fro shipment of the Data Box Disk.

No. The Data Box Disk resource doesn't need to be the same as the storage account region where you want to transfer data. You can choose a storage account in any region within the country or commerce boundary selected during the order. The Data Box Disk region is only used to deploy the resource during order creation. This is fixed for each country or commerce boundary and can't be changed.

In extreme circumstances where a region is lost because of a significant disaster, Microsoft might initiate a regional failover. No action on your part is required in this case. Your order is fulfilled through the failover region if it is within the same country or commerce boundary. However, some Azure regions don't have a paired region in the same geographic or commerce boundary. If there is a disaster in any of those regions, you will need to create the Data Box order again from a different region that is available, and copy the data to Azure in the new region. For more information, see Cross-region replication in Azure: Business continuity and disaster recovery.

If you encounter any issues with Data Box Disks, contact Microsoft Support.

To get Azure Data Box Disk, sign in to the Azure portal and create a Data Box Disk order. Provide your contact information and notification details. Once you place an order, based on the availability, Data Box Disk is shipped to you within 10 days. For more information, go to Order a Data Box.

If you can't create a Data Box Disk order, there's a problem with either your subscription type or access.

Check your subscription. Data Box Disk is only available for Enterprise Agreement (EA) and Cloud solution provider (CSP) subscription offers. If you don't have either of these subscription types, contact Microsoft Support to upgrade your subscription.

If you have a supported offer type for the subscription, check your subscription access level. You need to be a contributor or owner in your subscription to create an order.

The following estimated lead times for each phase of order processing will give you a good idea of what to expect.

These lead times are estimates. The time for each stage of order processing is affected by load on the datacenter, concurrent orders, and other environmental conditions.

Estimated lead times for a Data Box Disk order:

1. Order Data Box Disk: A few minutes, from the portal
2. Disk allocation and preparation: Up to 5 business days, depending on inventory availability and number of pending orders to be processed
3. Shipping: 2-3 business days
4. Data copy at customer site: Depends on nature of data, size, and number of files.
5. Return shipping: 2-3 business days
6. Processing at the datacenter and upload to Azure: Data upload begins at the datacenter as soon as operational processing is complete and the disk is connected. Upload time depends on nature of data, size, and number of files.

No, only import is supported for Data Box Disk. Export functionality is not available. If you want to export data from Azure, you can use Azure Data Box.

No. You get 8-TB disks (a maximum of five disks) depending upon your data size and availability of the disks.

In the Azure portal, go to your Data Box Disk order, and navigate to Device details. Copy the passkey. Download and extract the Data Box Disk unlock tool from the Azure portal for your operating system. Run the tool on the computer that has the data you want to copy to the disks. Provide the passkey to unlock your disks. The same passkey unlocks all the disks.

For step-by-step instructions, go to Unlock disks.

Yes. Both the Linux and Windows clients can be used to connect and copy data on to the Data Box Disks. For more information, go to the list of Supported operating systems for your host computer.

You can only cancel the order after the disks are ordered and before the shipment. Once the disks are dispatched, you can no longer cancel the order. However, you can return your disks at a charge.

Yes. Multiple Data Box Disks can be connected to the same host computer to transfer data and multiple copy jobs can be run in parallel.

You can track the status of the Data Box Disk order in the Azure portal. When you create the order, you are also prompted to provide a notification email. If you have provided one, then you're notified via email on all status changes of the order. More information on how to Configure notification emails.

Microsoft provides a shipping label with the Data Box Disks in the shipping package. Affix the label to the shipping box and drop off the sealed package at your shipping carrier location. If the label is damaged or lost, go to Overview > Download shipping label and download a new return shipping label.

Yes. Microsoft also offers self-managed shipping in US Gov region only. When placing the Data Box Disk order, you can choose self-managed shipping option. To pick up your Data Box Disk order, take the following steps:

1. After you place the order, the order is processed and the disks are prepared. You will be notified via an email that your order is ready for pickup.
2. Once the order is ready for pickup, go to your order in the Azure portal and navigate to the Overview blade.
3. You will see a notification with a code in the Azure portal. Email the Azure Data Box Operations team and provide them with the code. The team will provide the location and schedule a pickup date and time. You must call the team within 5 business days after you receive the email notification.

Once the data copy and validation is complete, take the following steps to return your disk:

1. Once the data validation is complete, unplug the disks. Remove the connecting cables.

2. Wrap all the disks and the connecting cables with a bubble wrap and place them in the shipping box. Charges may apply if the accessories are missing.

   • Reuse the packaging from the initial shipment. We recommend that you pack disks using a well-secured bubbled wrap.
   • Make sure the fit is snug to reduce any movements within the box.

3. Go to the Overview blade for your order in Azure portal. You should see a notification with a code.

4. Use that code and email the Azure Data Box Operations team and provide them with the code. They would provide you with information on where and when to drop off the disks.

Data Box Disks solution can have up to 5 disks with a maximum usable capacity of 35 TB. The disks themselves are 8 TB (usable 7 TB).

The maximum sizes are governed by Azure Storage limits. The maximum block blob is roughly 4.768 TiB and the maximum page blob size is 8 TiB. For more information, see Scalability and performance targets for Blob storage.

When tested with disks connected via USB 3.0, the disk performance was up to 430 MB/s. The actual numbers vary depending upon the file size used. For smaller files, you may see lower performance.

Data Box Disks are encrypted using BitLocker AES-128 bit encryption and the passkey is only available in the Azure portal. Log in to the Azure portal using your account credentials to get the passkey. Supply this passkey when you run the Data Box Disk unlock tool.

Use an SMB copy tool such as Robocopy, Diskboss, or even Windows File Explorer drag-and-drop to copy data onto disks.

To speed up the copy process:

• Use multiple streams of data copy. For instance, with Robocopy, use the multithreaded option. For more information on the exact command used, go to Tutorial: Copy data to Azure Data Box Disk and verify.
• Use multiple sessions.
• Instead of copying over network share (where you could be limited by the network speeds) ensure that you have the data residing locally on the computer to which the disks are connected.
• Ensure that you're using USB 3.0 or later throughout the copy process. Download and use the USBView tool to identify the USB controllers and USB devices connected to the computer.
• Benchmark the performance of the computer used to copy the data. Download and use the Bluestop FIO tool to benchmark the performance of the server hardware. Select the latest x86 or x64 build, select the Artifacts tab, and download the MSI.

To speed up the copy process:

• Create a local VHDx on fast storage or create an empty VHD on the HDD/SSD (slower).
• Mount it to a VM.
• Copy files to the VM's disk.

No. Only one storage account, general or classic, is currently supported with Data Box Disks. Both hot and cool blob are supported.

The toolset available with the Data Box Disk contains three tools:

• Data Box Disk Unlock tool: Use this tool to unlock the encrypted disks that are shipped from Microsoft. When unlocking the disks using the tool, you need to provide a passkey available in the Data Box Disk order in the Azure portal.
• Data Box Disk Validation tool: Use this tool to validate the size, format, and blob names as per the Azure naming conventions. It also generates checksums for the copied data, which are then used to verify the data uploaded to Azure.
• Data Box Disk Split Copy tool: Use this tool when you're using multiple disks and have a large dataset that needs to be split and copied across all the disks. This tool is currently available for Windows. This tool isn't supported with managed disks. This tool validates the data as it copies it, so you can skip the validation step when using this tool.

The toolset is available both for Windows and Linux. You can download the toolset here:

• Download Data Box Disk toolset for Windows
• Download Data Box Disk toolset for Linux

Azure Files are supported with Data Box Disk but won't work well with Azure File Sync. Data Box Disk will transfer file/directory timestamps, attributes, and ACLs to Azure Files. Azure File Sync usage with Data Box disk is now supported.

Once the order status for Data Copy shows as complete, you should be able to access your data right away.

When you copy the data under BlockBlob and PageBlob folders on your disk, a container is created in the Azure storage account for each subfolder under the BlockBlob and PageBlob folder. If you copied the files under the BlockBlob and PageBlob folders directly, then the files are in a default container $root under the Azure Storage account. When you copy the data into a folder under AzureFile folder, a fileshare is created.

Any uppercase letters in your container names are automatically converted to lowercase. If the names aren't compliant in other ways - for example, they contain special characters or other languages - the upload will fail. For more information, go to Azure naming conventions.

After the data copy is complete, you can run DataBoxDiskValidation.cmd provided in the DataBoxDiskImport folder to generate checksums for validation. If you have multiple disks, you need to open a command window per disk and run this command. Keep in mind that this operation can take a long time (~hours) depending upon the size of your data.

Once the data copy to Azure is complete, the data from the disks is securely erased as per the NIST SP 800-88 Revision 1 guidelines.

The Data Box Disks are encrypted with AES-128 Microsoft BitLocker encryption, and a single passkey is required to unlock all the disks and access data.

Yes. If you decide to validate your data (we recommend you do!), you need to rerun validation if you added more data to the disks.

You can clone your previous order. Cloning creates the same order as before and allow you to edit order details only without the need to type in address, contact, and notification details.

Yes. Your data was uploaded to Azure, but if you don't see any managed disks with the specified resource groups, it's likely because the data wasn't valid. If page blobs, block blobs, Azure Files, or managed disks aren't valid, they'll go to the following folders:

• Page blobs go to a block blob container starting with databoxdisk-invalid-pb-.
• Azure Files will go to a block blob container starting with databoxdisk-invalid-af-.
• Managed disks go to a block blob container starting with databoxdisk-invalid-md-.
