What Is DES?

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.

Application Scenario

Migration Medium

How to Obtain the Migration Medium

By Teleport

  • Migration of 30 to 500 TB of data. If the data volume is larger than 500 TB, you are advised to use the Direct Connect service.

  • Users having no large-capacity storage media
  • Urgent data migration that requires fast speed and short time

Teleport. The capacity of a single Teleport is 60 TB.

Huawei data centers mail Teleports to you.

By Disk

Migration of less than 30 TB of data

External USB hard disks, SATA disks, and SAS disks

For details about the specifications, interfaces, and file systems supported by each type of disks, see What Are the Requirements for Disks by Disk-based DES?.

You need to prepare disks for transmission.

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.
