          ### What is Azure Data Box service?
          :::zone pivot="dbx-ng"
          The Microsoft Azure Data Box cloud solution lets you send terabytes of data into and out of Azure in a quick, inexpensive, and reliable way. The secure data transfer is accelerated by shipping you a proprietary Data Box storage device. These storage devices come in two variations having a maximum usable storage capacity of 120 TB and 525 TB respectively. These are transported to your data center through a regional carrier. These devices have a rugged casing to protect and secure data during the transit. 
          :::zone-end

          Azure Data Box service is designed for offline data ingestion. This service manages an array of products of differing storage capacities, all tailored for data transport. 
            
          ### What is Azure Data Box?
          
          The Azure Data Box allows a quick, inexpensive, and secure transfer of terabytes of data into Azure. You order the Data Box device via the Azure portal. Microsoft ships you a storage device through a regional carrier.

          ### Which Data Box model should I use?

          If you have 40 - 480 TB of data that you want to transfer to or from Azure, you would benefit from using Data Box 120. For data sizes < 40 TB, use [Data Box Disk](data-box-overview.md), and for data sizes > 480 TB, use Data Box 525. If you have 40 - 500 TB of data that you want to transfer to or from Azure, you would benefit from using Data Box. For data sizes < 40 TB, use [Data Box Disk](data-box-overview.md), and for data sizes > 500 TB, sign up for [Data Box Heavy](data-box-heavy-overview.md).

          ### What is the price of Data Box?

          Data Box 120 and Data Box is available at a nominal charge for 10 days. Data Box 525 is available at a nominal charge for 20 days. When you select the product model while creating an order in the Azure portal, the charges for the device are displayed. Standard shipping charges and charges for Azure storage also apply. Export orders follow a similar pricing model as for import orders, though additional egress charges may apply.

          For more information, go to [Azure Data Box pricing](https://azure.microsoft.com/pricing/details/storage/databox/) and [Azure Data Box Heavy pricing]( https://azure.microsoft.com/en-us/pricing/details/databox/heavy/). For egress charges, see [Bandwidth pricing](https://azure.microsoft.com/pricing/details/bandwidth/).

          ### Does Data Box store any customer data outside the service region?

          No. Data Box does not store any customer data outside of the service region. The customer has full ownership of their data. They 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 is Data Box data that includes security artifacts related to the device, monitoring logs for the device and the service, and service-related metadata. In all regions (except Brazil South, Southeast Asia, and East Asia), Data Box data is stored and replicated in the paired region via a Geo-redundant Storage account to protect against data loss.

          Due to [data residency requirements](https://azure.microsoft.com/global-infrastructure/data-residency/#more-information) in Brazil South, Southeast Asia, and East Asia, Data Box data is stored in a Zone-redundant Storage (ZRS) account so that it is contained in a single region. For Southeast Asia, all the Data Box data is stored in Singapore. For Brazil South, the data is stored in Brazil. For East Asia, the data is stored in Hong Kong SAR.

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

          ### Does my Data Box region have to be in the same Azure region as my destination storage account?

          No. The Data Box resource does not 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/region or commerce boundary selected during the order. The Data Box region is only used to deploy the resource during order creation. This is fixed for each country/region or commerce boundary and cannot be changed.

          ### How can I recover my data if an entire region fails?

          In extreme circumstances where a region is lost because of a significant disaster, Microsoft may initiate a regional failover. No action on your part is required in this case. Your order will be fulfilled through the failover region if it is within the same country/region 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 [Business continuity and disaster recovery (BCDR): Azure Paired Regions](../best-practices-availability-paired-regions.md).

          ### Who should I contact if I come across any issues with Data Box?

          If you come across any issues with Data Box, [contact Microsoft Support](data-box-disk-contact-microsoft-support.md).

          ### I lost my Data Box. Is there a lost device charge?

          Yes. There is a charge for a lost or damaged device. This charge is covered on the [Pricing page](https://azure.microsoft.com/pricing/details/storage/databox/) and in the [Product Terms of Service](https://www.microsoft.com/licensing/product-licensing/products). Scroll down to "Frequently asked questions" for the product and look for "Lost device fee."

          ## [Data Box & Data Box Heavy](#tab/data-box-and-data-box-heavy)
          
          ### I couldn't create a Data Box/Data Box Heavy order in the Azure portal. Why?

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

          Check your subscription. Data Box 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.

          ### I ordered a couple of Data Box devices. I can't create any additional orders. Why?

          We allow a maximum of five active orders per subscription per commerce boundary (combination of country/region and region selected) for any Data Box product. You can have up to five active Data Box 120 orders, five active Data Box 525 orders, five active Data Box orders, and five active Data Box Heavy orders. If you need to order an additional device, contact Microsoft Support to increase the limit for your subscription. 

          ### When I try to create an order, I receive a notification that the Data Box service is not available. What does this mean?

          The Data Box service isn't available for the combination of country/region and region you selected for the selected product - either Data Box 120, Data Box 525, Data Box, or Data Box Heavy. Changing this combination would likely allow you to avail of the Data Box service. For a list of the regions where the service is available, go to [Region availability for Data Box](data-box-overview.md#region-availability) or [Region availability for Data Box Heavy](data-box-heavy-overview.md#region-availability).

          ### My Data Box is dispatched, but now I want to cancel this order. Why is the cancel button not available?

          You can only cancel the order after the Data Box is ordered and before the order is processed. Once the Data Box order is processed, you can no longer cancel the order.

          ### I have filled up my Data Box with data and need to order another one. Is there a way to quickly place the order?

          You can clone your previous order. Cloning creates the same order as before and allows you to edit order details only without the need to type in address, contact, and notification details. Cloning is allowed only for import orders. For more information, see [Clone an order](data-box-portal-admin.md#clone-an-order).
          
          ## [Data Box only](#tab/data-box)

          ### How do I get Data Box?

          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 order:**

          1. Order Data Box: A few minutes, from the portal

          2. Device allocation and preparation: 1-2 business days, subject to inventory availability and other orders pending fulfillment

          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 device at datacenter: 1-2 business days, subject to other orders pending processing

          7. Upload data to Azure: Begins as soon as processing is complete and the device is connected. Upload time depends on nature of data, size, and number of files.

          ### I placed my Data Box order few days back. When will I receive my Data Box?

          When you place an order, we check whether a device is available for your order. If a device is available, we will ship it within 10 days. It is conceivable that there are periods of high demand. In this situation, your order will be queued and you can track the status change in the Azure portal. If your order is not fulfilled in 90 days, the order is automatically canceled.

          ## [Data Box Heavy only](#tab/data-box-heavy)

          ### How do I get a Data Box Heavy device?

          Data Box Heavy requires a sign-up when ordering a device. Use the **Request Heavy** button on the initial order screen, and send your migration details. We will be in touch with you within 1-2 business days. Once you enable Data Box Heavy for your subscription, a **Select** button replaces **Request Heavy**, and you can continue with your order. 

          ### What carrier services can I use for my Data Box Heavy order?

          Because of their size and weight, Data Box Heavy devices require special handling. For this reason, we recommend that you use the white glove delivery service, which is used commonly by most Data Box Heavy customers. The white glove service delivers the crate to your premises, unpacks the device, and then keeps the crate for return of the device, which is arranged through Operations.

          If you want to do your own shipping through a different carrier, contact Operations to get detailed shipping requirements. After you uncrate the device, you must save the crate and use it for the return shipment.

          ### Can I connect to both of the 10-GbE interfaces on the Data Box, or the 100-GbE interfaces on the Data Box Next-Gen, to transfer data?

          Yes. Both of the interfaces can be connected on the Data Box or Data Box Next-Gen to copy data at the same time. For more information on how to copy data, go to [Tutorial: Copy data to Azure Data Box](data-box-deploy-copy-data.md).

          ### I can't access the Data Box unlock password in the Azure portal. Why?

          If you aren't able to access the unlock password in the Azure portal, check the permissions on your subscription and storage account. Ensure that you have contributor or owner permission at resource group level. You need to have at least Data Box Operator role permission to see the access credentials.

          ### Is port channel configuration supported on Data Box? How about MPIO?

          We don't support port channel configuration, Multipath IO (MPIO) configuration, or vLAN configuration on Data Box.

          ### When do the automatically generated self-signed certificates on my device expire?

          [!INCLUDE [return-data-box-before-certificates-expire](../../includes/data-box-certificate-expiration.md)]

          ### How do I verify the data I copied onto my Data Box?

          After the data copy is complete, when you run **Prepare to ship**, your data is validated. Data Box generates a list of files and checksums for the data during the validation process. You can download the list of files and verify the list against the files in the source data. For more information, go to [Prepare to ship](data-box-deploy-prepare-to-ship.md#prepare-to-ship).
          
          ## [Data Box only](#tab/data-box)     

          ### The system fault indicator LED on the front operating panel is on. What should I do?

          There are two LED lights under the power button on the front of a Data Box. The bottom-most light is the system fault indicator, which indicates whether your system is healthy.

          A system fault indicator LED that is red may indicate one of the following issues:
          * Fan failure
          * CPU temperature is high
          * Motherboard temperature is high
          * Dual inline Memory Module (DIMM) Error Connecting Code (ECC) error

          Take these steps:
          1. Check whether the fan is working.
          2. Move the device to a location with greater airflow.
          3. If the system fault indicator light is still on, [contact Microsoft Support](data-box-disk-contact-microsoft-support.md).

          ### The disk status indicator LED on the front operating panel is flashing yellow. What does this mean?

          The top-most light is the disk status indicator. If this light is flashing yellow, this means there is RAID HDD activity. If it is off, there is no RAID HDD activity.

For larger data sizes up to 480 TB, you can order multiple Data Box 120 devices. For data sizes exceeding 480 TB, order Data Box 525. Data Box has a usable storage capacity of 80 TB. You can use a single Data Box device for data that ranges in size from 40 TB - 80 TB. For larger data sizes up to 500 TB, you can order multiple Data Box devices. For data sizes exceeding 500 TB, sign up for Data Box Heavy.

          ### What are the maximum block blob and page blob sizes supported by Data Box? 

          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](../storage/blobs/scalability-targets.md).

          ### How do I know that my data is secure during transit?

          There are multiple security features implemented to ensure that your Data Box is secure during transit. Some of these include tamper-evident seals, hardware and software tampering detection, and a device unlock password. For more information, go to [Azure Data Box security and data protection](data-box-security.md).

          ### How do I copy the data to the Data Box?

          If using an SMB client, you can use an SMB copy tool such as `Robocopy`, `Diskboss`, or even Windows File Explorer drag-and-drop to copy data onto the device.

          If using an NFS client, you can use [rsync](https://rsync.samba.org/), [FreeFileSync](https://www.freefilesync.org/), [Unison](https://www.cis.upenn.edu/~bcpierce/unison/), or [Ultracopier](https://ultracopier.first-world.info/).

          For more information, go to [Tutorial: Copy data to Azure Data Box](data-box-deploy-copy-data.md) or [Tutorial: Copy data to Azure Data Box Heavy](data-box-heavy-deploy-copy-data.md).

          ### Are there any tips to speed up the data copy?

          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 and verify](data-box-deploy-copy-data.md).
          
          - Use multiple sessions.
          
          - Instead of copying over a network share (where network speeds can limit copy speed), store the data locally on the computer to which the Data Box is connected.
          
          - Benchmark the performance of the computer used to copy the data. Download and use the [`Bluestop` `FIO` tool](https://ci.appveyor.com/project/axboe/fio) to benchmark the performance of the server hardware. Select the latest x86 or x64 build, select the **Artifacts** tab, and download the MSI.

          ### Can I use Data Box to import data to a storage account with private endpoints configured?

          Yes. You can import data to a storage account that has private endpoint connections enabled. To let the Data Box service import the data, select "Allow trusted Microsoft services to access this storage account" under the Networking section of the storage account.

          ### Can I use multiple storage accounts with Data Box?

          Yes. A maximum of 10 storage accounts, general purpose, classic, or blob storage are supported with Data Box. Both hot and cool blob are supported.
          > [!Note]
          > Classic storage accounts will not be supported starting **August 1, 2023**.

          ## [Data Box & Data Box Heavy](#tab/data-box-and-data-box-heavy)
          
          ### Will my Data Box devices cross country/region borders during shipping?

          All Data Box devices are shipped from within the same country/region as their destination and will not cross any international borders. The only exception is for orders in the European Union (EU), where devices can ship to and from any EU country/region. This policy applies to both Data Box devices.

          ### How is my data protected during transit?

          During transit, the following features on the Data Box help protect the data.
          - The Data Box disks are encrypted with AES 256-bit encryption and RAID controller hardware encryption.
          - The device is locked and needs an unlock password to enter and access data.
          For more information, go to [Data Box security features](data-box-security.md).

          ### I finished Prepare to Ship for my import order and shut down the device. Can I still add more data to the Data Box?

          Yes. You can turn on the device and add more data. You'll need to run **Prepare to Ship** again once you have completed the data copy.

          ## [Data Box only](#tab/data-box)

          ### My device was delivered, but the device seems to be damaged. What should I do?

          If your device arrived damaged or there is evidence of tampering, do not use the device. [Contact Microsoft Support](data-box-disk-contact-microsoft-support.md) and return the device as soon as possible. You can also create a new Data Box order for a replacement device. In this case, you won't be charged for the replacement device.

          ### I received my device and it's not booting up. How do I ship the device back?

          If your device isn't booting, [contact Microsoft Support](data-box-disk-contact-microsoft-support.md) for help.

          ### Can I pick up my Data Box order myself? Can I return the Data Box via a carrier that I choose?

          Yes. Microsoft also offers self-managed shipping. When placing the Data Box order, you can choose self-managed shipping option. For more information, see [Use self-managed shipping for Data Box](data-box-portal-customer-managed-shipping.md).

          ### I ordered a Data Box in US East, but I received a device that was shipped from a location in US West. Where should I return the device to?

          We try to get a Data Box device to you as quickly as possible. We prioritize the shipment from a datacenter closest to your storage account location but will ship a device from any Azure datacenter that has available inventory. Your Data Box should be returned to the same location where it was shipped from as displayed in the shipping label.

          ### I need to ship a Data Box to Puerto Rico. Are there any special requirements?

          If you need to have a device shipped to Puerto Rico, email [adbops@microsoft.com](mailto:adbops@microsoft.com) for instructions. You'll be asked to create an order using a United States address but provide the Operations team a Puerto Rico address via email. Shipping a device to Puerto Rico doesn't add any extra shipping cost from UPS.

          ### E-ink display is not showing the return shipment label. What should I do?

          Whether or not the E-Ink showing return shipment label, you must download the shipping label from the local web UI on the device after completing the **Prepare to ship** step. For more information, see [Prepare to ship](data-box-deploy-prepare-to-ship.md#prepare-to-ship).
          
          When you have the shipping label, remove the old label from the device packaging and any sticker from the previous shipment. Paste the new label onto the packaging box, ensuring that the shipping label is clearly visible.

          ### Can I transport the Data Box to the Azure datacenter?

          No. If you have chosen Microsoft managed shipping, you can't transport the data. Currently, Azure datacenter does not accept delivery of the Data Box from customers or from carriers other than UPS.

          If you chose self-managed shipping, then you can pick up or drop off your Data Box from the Azure datacenter.

          ### My device was delivered, but the device seems to be damaged. What should I do?

          If your device arrived damaged or there is evidence of tampering, do not use the device. [Contact Microsoft Support](data-box-disk-contact-microsoft-support.md) and return the device as soon as possible. You can also create a new Data Box Heavy order for a replacement device. In this case, you won't be charged for the replacement device.

          ### I received my device and it's not booting up. How do I ship the device back?

          If you used White Glove service for your Data Box Heavy order, email [adbops@microsoft.com](mailto:adbops@microsoft.com) to arrange for return of the device. 
          
          If you used a different carrier, you'll need to return the device in the crate that it was shipped in. Email [adbops@microsoft.com](mailto:adbops@microsoft.com) for instructions.
          
          ### Can I pick up my Data Box Heavy order myself? Can I return the Data Box Heavy device via a carrier that I choose?

          No. You can't pick up your Data Box Heavy order yourself. 
          
          As for returning the device, if you used the White Glove service for your Data Box Heavy order, the White Glove service will manage return of the device also. Email [adbops@microsoft.com](mailto:adbops@microsoft.com) to make the arrangements. 
          
          If you didn't use the White Glover service for your order, you'll need to return your device, *in the same crate*, using the service delivered the device. Email [adbops@microsoft.com](mailto:adbops@microsoft.com) for more information.

          ### How soon can I access my data in Azure once I've shipped the Data Box back? 

          Once the order status for **Data Copy** shows as **Complete**, you can access your data right away.

          ### Where is my data located in Azure after the upload?

          When you copy the data to Data Box, depending on whether the data is block blob or page blob or Azure files, the data is uploaded to one of the following paths in your Azure Storage account:
          - `https://<storage_account_name>.blob.core.windows.net/<containername>` 
          - `https://<storage_account_name>.file.core.windows.net/<sharename>`
           
          Alternatively, you could go to your Azure storage account in the Azure portal and navigate from there.

          ### I just noticed that I did not follow the Azure naming requirements for my containers. Will my data fail to upload to Azure?

          If the container names have uppercase letters, those names are automatically converted to lowercase. If the names are not compliant in other ways (special characters, other languages, and so on), the upload will fail. For more guidance for naming shares, containers, and files, go to:
          - [Naming and referencing shares](/rest/api/storageservices/naming-and-referencing-shares--directories--files--and-metadata)
          - [Block blobs and page blob conventions](/rest/api/storageservices/understanding-block-blobs--append-blobs--and-page-blobs).

          ### I was notified of copy errors during a data upload from my Data Box. What should I do?

          When non-retryable data copy errors prevent any files in your import order from uploading to Azure, the errors are logged in the data copy log and you get a notification. You can't fix the errors. The upload has completed with errors. The notification is sent to make sure you know that the files didn't upload so you can fix any configuration errors before you try again. When you confirm that you're ready to proceed, the data will be secure erased from the device. If you don't respond, the order completes automatically after 14 days.
          
          For error information and steps to proceed with your order, see [Review copy errors in uploads from Azure Data Box and Azure Data Box Heavy devices](data-box-troubleshoot-data-upload.md).

          ### I'm seeing date entries with "Fri, 31 Dec 9999 23:59:59" on some files. What does that mean? 

          [!INCLUDE [data-box-file-date-substitution](../../includes/data-box-file-date-substitution.md)]

          ### What happens to my data after I return the Data Box?

          Once the data upload to Azure is complete, the data from the disks on the Data Box is securely erased as per the NIST SP 800-88 Revision 1 guidelines. For more information, go to [Erasure of data from Data Box](data-box-deploy-picked-up.md#erasure-of-data-from-data-box).

          ### How does Azure Data Box service help support customers' chain of custody procedure?

          Azure Data Box service natively provides reports that you can use for your chain of custody documentation. The audit and copy logs are available in your storage account in Azure and you can [download the order history](data-box-portal-admin.md#download-order-history) in the Azure portal after the order is complete.

          ### What type of reporting is available to support chain of custody?

          Following reporting is available to support chain of custody:
          - Transport logistics from UPS.
          - Logging of powering on and user share access.
          - BOM or manifest file with a 64-bit cyclic redundancy check (CRC-64) or checksum for each file ingested successfully into the Data Box.

           ### Are the carrier tracking logs (from UPS) available?

           Carrier tracking logs are captured in the Data Box order history. This report is available to you after the device has returned to Azure datacenter and the data on device disks is cleaned up. For immediate need, you can also go directly to the carrier's website with the order tracking number and get the tracking information.
