Creating databox

Available in Classic and VPC

Databox can be created after requesting the Cloud Data Box subscription. When creating the databox, select the analysis service to use on the databox and set the server for connecting to the analysis service. Once the databox is created, settings for other infrastructure services excluding NAS and SSL VPN can't be changed. So, please make your choice carefully.

1. Select Infrastructure product

To use the databox, you must select analysis services such as Cloud Hadoop and TensorFlow as well as Connect Server for accessing the analysis services.

• Connect Server: It is a server provided by Windows OS. You can connect to Cloud Hadoop and Ncloud TensorFlow Server using PuTTY on Connect Server. You can also use Ambari, Zeppelin, Jupyter Notebook, etc., via a web browser on Connect Server.
• SSL VPN: You must use SSL VPN to connect to the server provided.
• NAS: Used to import files from external sources or export analysis results after external communications are blocked. NAS is mounted on all of Cloud Hadoop, TensorFlow CPU, TensorFlow GPU, and Linux servers, which means files can easily be shared among Cloud Hadoop, Ncloud TensorFlow Server, and Linux server.

You can create the databox as follows.

1. From the NAVER Cloud Platform console, click the Services > Big Data & Analytics > Cloud Data Box menus, in that order.
2. Click the [Request databox] button.
   • A page for selecting the infrastructure environment for analysis.
3. Select Connect Server specifications and number.
   • You can create two user accounts per Connect Server and up to two users can connect simultaneously. Therefore, you should choose the number of Connect Servers according to the number of analysts.
4. Select the number of SSL VPN accounts required.
   • Email or mobile phone authentication is required when connecting via SSL VPN. Therefore, a separate SSL VPN account must be created for each user.
   • SSL VPN can only be requested up to 3 times the number of Connect Servers.
5. Enter the capacity and quantity of NAS to create and click the [Add] button.
   • The default capacity of a NAS volume ranges from 500 GB to 10,000 GB. Additions can be made in units of 100 GB.
   • If you're reusing an existing NAS volume, then you don't need to create a new NAS. If you're not reusing an existing NAS volume, then you must create one or more NAS.
6. Select an edge node and a master node in the Cloud Hadoop area.
   • The number of edge nodes and master nodes are fixed values, and can't be changed.
7. In the Cloud Hadoop area, select worker nodes, and select the number of worker nodes.
   • The number of worker nodes can't be changed after the databox is created.
8. Set specifications and quantity of Ncloud TensorFlow Server.
   • At least one Ncloud TensorFlow Server (CPU) and Ncloud TensorFlow Server (GPU) must be requested.
9. If you wish to additionally create Linux servers, then select the server OS, specifications, and quantity, and click the [Add] button.
10. After checking the request details, click the [Next] button.
    

2. Enter product information

This is the step for entering the name of the databox, and set the connection details for Connect Server, Cloud Hadoop, and TensorFlow (CPU/GPU) servers. As account name for each server is generated automatically, and you only need to set the password. The following describes how to set the name and connection details of a databox.

1. Enter the databox name.
   • Only Korean and English letters, numbers, and the special character "-" are allowed. Names must be between 3 to 20 characters.
2. Enter password for Connect Server.
   • Create two accounts on Connect Server
   • Connect Server accounts are generated as "ncp1" and "ncp2."
3. Enter the password of the Hadoop cluster.
   • Cloud Hadoop accounts are generated as "ncp."
4. Enter password for the TensorFlow (CPU/GPU) servers.
   • TensorFlow accounts are generated as "root."
5. Enter password for the added Linux server.
   • Linux server accounts are generated as "root."
6. After checking the details entered, click the [Next] button.
   

3. Final confirmation

This is the step for requesting databox creation after confirming request details in the previous step for the last time. It may take several hours or more for the databox to be created. Once the databox is created, you will be notified via email. The following describes how to confirm the data creation details for the last time.

1. Make sure that the databox name is requested correctly.
2. Make sure that infrastructure services are requested correctly.
3. Review the details, and then click the [Confirm] button.
