Data Express Service Product Introduction 1 Product Overview

1 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 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 highspeed Internet transmission but at only one fth 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.

ash drives, SATA disks,

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 1-1. 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.

● 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 of a single Teleport is 60 TB.

How to Obtain the Migration Medium

How to Obtain the Migration Medium

You need to prepare disks.

DES saves your eort 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

eciently.

Data Express Service Product Introduction 2 Functions

2 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. Teleport has safety lock, alarm recording, GPS tracking, and restricted area unlock functions.

– 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 data type, and le storage mode.

– For Teleport-based DES, the data upload rate is aected by the type and

size of the data le. The transmission rate of common les can reach 500 MB/s, and the transmission rate of massive small les can reach 200 MB/s. Therefore, you can preferentially select the Teleport-based DES to achieve fast and ecient data transmission.

aected by the device performance, data volume,

les and ultra-large

– For disk-based DES, the data upload rate depends on the I/O

performance of your disks. The transmission rate of a common USB 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.
