Product Overview

Data Express Service (DES) is a TB- or PB-scale data transmission service. It uses physical storage media (such as Teleport, external USB flash drives, SATA disks, and SAS disks) to transmit a large amount of data to HUAWEI CLOUD. DES provides a data transmission speed at 1000 Mbit/s, 10 times faster than high-speed Internet transmission but at only one fifth of the cost. It helps to address issues facing massive data transmission such as high network costs and long transmission time. DES does not occupy your public network bandwidth or compete with main services for bandwidth resources.

Currently, DES supports two data transmission modes: by Teleport and by disk. Teleport suits TB- and PB-scale data migration, while disks are preferred for data migration at TB level. Select a transmission mode based on the amount of data to be transmitted. For details, see Table 1. For Teleport-based DES, you will receive a Teleport sent by a Huawei data center (DC). For disk-based DES, you need to prepare disks by yourself.

Table 1 Application scenarios

Transmission Mode

Application Scenario

Migration Medium

How to Obtain the Migration Medium

Teleport-based DES

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

Teleport. The capacity options of a single Teleport are 60 TB and 120 TB.

DC mails Teleports to customers.

Disk-based DES

TB-scale data migration

External USB flash drives, SATA disks, and SAS disks

For details about the specifications, interfaces, and file systems supported by each type of disks, see Disk compatibility.

You need to prepare disks.

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 media to transmit data to HUAWEI CLOUD securely, quickly, and efficiently.
