Data Express Service (DES) is a TB-scale data transmission service. It provides physical storage devices (such as Teleport, external USB hard disks, SATA disks, and SAS disks) to make it easier for you to transmit terabytes of data to HUAWEI CLOUD. DES offers up to 1,000 Mbit/s transmission speed, almost 10 times faster than would be possible over Internet, at only one fifth of the Internet cost. DES does not occupy the public network bandwidth or the bandwidth of main businesses.

DES allows you to transmit data by Teleport or by disk. Select the transmission mode based on the data volume to be transmitted.

• Data volume < 30 TB: Use disks.
• 30 TB < data volume < 500 TB: Use Teleport.
• Data volume > 500 TB: Use the Direct Connect service.

For Teleport-based DES, you will receive a Teleport sent by a Huawei data center. For disk-based DES, you need to prepare disks by yourself. See Table 1 for more information.

DES saves your effort and money in writing code or buying any hardware for data transmission. You only need to create service orders on DES Console and use Teleports or disks as the storage medium to transmit data to HUAWEI CLOUD securely, quickly, and efficiently.
