Functions

DES has the following functions:

  • Security guarantee

    DES has a comprehensive security mechanism to protect your data from being maliciously accessed and tampered with.

    • Security assurance of the migration medium: Teleport-based DES provides Teleport which is dust- and water-proof and resistant to vibration and crush. It also has safety lock.
    • Security assurance during data transmission: After the migration medium storing your data is received by the Huawei DC, the administrator mounts the Teleport or the disk to the server. Then an SMS message is sent to notify you of inputting the access keys (AK/SK). After the key authentication is successful, data upload is triggered. In this manner, Huawei personnel have no access to your keys or data, ensuring data security during transmission.
  • Transmission rate
    One of the important features of DES is to provide a high-speed transmission rate to solve the problem of long data transmission time. The upload speed of local data is severely limited by your network bandwidth. DES stores your data in the migration medium and transports the data to a Huawei DC to solve the problem of limited network bandwidth. In addition, DES provides the option of Teleport which has high I/O performance. However, the DES transmission rate is still affected by the device performance, data volume, data type, and file storage mode.
    • For Teleport-based DES, the data upload rate is affected by the type and size of the data file. The transmission rate of common files can reach 500 MB/s, and the transmission rate of massive small files and ultra-large files can reach 200 MB/s. Therefore, you can preferentially select the Teleport-based DES to achieve fast and efficient data transmission.
    • For disk-based DES, the data upload rate depends on the I/O performance of your disks. The transmission rate of a common USB flash drive is 30 MB/s, and the transmission rate of a SATA disk is 100 MB/s.
  • Teleport can import data that complies with the NFS/CIFS/FTP protocol to OBS, migrating massive data to the cloud.
  • Service status tracking

    DES provides complete process regulations of service orders. You can track the data transmission process based on the service order status information on the management console. The statuses of a Teleport-based DES order are different from those of a disk-based DES order. For details, see Figure 1 and Figure 2.

  • Mis-operation prevention

    A signature file is the unique identifier for matching a DES order with a migration medium. DES system identifies a signature file and automatically matches the migration medium with a service order to prevent mis-operations.

    After a service order is successfully placed, the system generates a unique signature file. You need to save the signature file to the root directory of the Teleport or disk, and mail the device to a Huawei DC. After the administrator receives and mounts the Teleport or disk to the server, the system automatically identifies the service order that matches the signature file information on the device. After the signature file matches the service order, the system triggers data upload based on the access keys (AK/SK) entered by you. Mis-operations are therefore prevented, because there is no manual intervention during the data upload.

  • Report generation

    You can obtain a report about your DES order details. After data uploading is complete, a report is generated for you to confirm that all data is transmitted.
