Creating a Disk-based DES Order

Background

If the data to be transmitted has been stored in the disk which is ready to be sent to a Huawei DC, you can create a disk-based order. For the types of disks supported by Huawei DCs, see Table 1.

An order supports a maximum of 12 disks, and each disk must have only one partition.

    Figure 2 Setting transmission information
    • Region: Select the region you want to store the transmitted data on Huawei Cloud.
    • Transmission Mode: Select By Disk.
    • Object Type: Set this parameter based on the size of data files to be transmitted.
      • Small file: File size < 10 MB
      • Common file: 10 MB ≤ File size < 1 GB
      • Ultra-large file: File size ≥ 1 GB
    • Object Quantity: Estimate the number of data files to be transmitted and select a level accordingly from Level 1 to Level 4. The larger the number, the more files are to be transmitted.
      • Level 1: Number of objects < 100,000
      • Level 2: 100,000 ≤ Number of objects < 1 million
      • Level 3: 1 million ≤ Number of objects < 10 million
      • Level 4: Number of objects ≥ 10 million
    • Number of Devices: Number of disks for storing data to be transmitted. Each disk-based order supports a maximum of 12 disks.
    • Handling Duplicate Files: Specify the method of handling duplicate files in the same directory. If you select Skip, the original file is retained. If you select Overwrite, the original file is replaced by the file that is being transferred.
    • (Optional) Disk File: Enter the file name or folder name under the root directory of the disk. If you enter a file name, the file is transmitted to the specified destination bucket. If you enter a folder name, all data in the folder is transmitted to the destination bucket. If you leave Disk File blank, all files in the disk are transmitted to the destination bucket by default.

      You can enter only one name in a text box. If you want to transmit more than one file or folder, click Add and type them into the newly added text boxes. For example, there are folders test01 and test02 in the root directory of a disk. You can enter them into two input boxes under Disk File and select two different destination buckets for data classification.

      A folder name cannot start with a dot (.) or contain any of the following characters: \/:*? "<>|

    • Destination Bucket: Click the folder icon next to Destination Bucket and select the destination bucket for disk-based data transmission. If there is no destination bucket, click Create Bucket to create one and refresh. You can also log in to Console, select Object Storage Service to create a bucket, and then refresh the destination bucket.
    • (Optional) Import Directory: Click the folder icon next to Import Directory and select the directory to which the data is to be imported. You can also enter a custom directory name. The backstage saves the data in this directory. If this parameter is not specified, your data is directly imported to the destination bucket.

      A maximum of 10 disk files or import directories can be created.

  6. Select a delivery address. When creating an order for the first time, you need to add a delivery address for receiving the disk mailed back by a Huawei DC. See Figure 3.

    Figure 3 Adding a delivery address
    • Contact: Enter the name of the contact person.
    • Country/Region: Enter the country or region where the contact person is located.
    • Delivery Address: Enter the district, city, and province of the contact person.
    • Address Details: Enter more information about the address, such as the street name and house number.

      You can create up to five delivery addresses.

      Cross-border transportation is not supported.

  7. Confirm the order information. Click Buy Now to confirm the delivery address and view details of the order.

    Check the order details. If there is incorrect information, click Previous to modify it.

    You can download the signature file here by clicking Download Signature File, or you can download it in the service list of DES Console.

You only need to upload AK/SK once for an order. After the order is created, in the order list, click More > Enter the access key (AK/SK) in the Operation column.
