Overview
Background
Conventional on-premises storage servers cannot meet the storage demands for massive amounts of data. The main reasons are as follows:
- Storage capacity is subject to hardware devices. If the storage capacity becomes insufficient, you need to purchase disks and expand the capacity manually.
- The initial deployment requires high investments and a long construction period, but it quickly lags behind as enterprise services change so fast.
- Network information vulnerabilities, technical vulnerabilities, and unintended operations may result in security risks.
In contrast, OBS provides massive, stable, and secure cloud storage capabilities. With OBS, you do not need to worry about the storage capacity because it can be expanded infinitely. OBS can store unstructured data of any type and size. OBS ensures high stability and security for your data, featuring a multi-level reliability architecture, server-side encryption, log management, and permission control. In terms of the cost, OBS is available upon service subscription, eliminating the need for the investment in physical server deployment and maintenance.
Huawei Cloud provides diverse migration solutions to help you migrate data from your on-premises storage servers to OBS in a cost-effective, secure, and efficient manner. You can select a suitable migration solution according to your data volume, time arrangement, and budget.
Migration Solutions
Table 1 describes the migration solutions provided by Huawei Cloud.
Solution |
Data Volume |
Requirement |
Time Required |
Pricing |
---|---|---|---|---|
Using OBS Tools to Migrate Data (online) |
Not larger than 1 TB |
The public network bandwidth must be idle and manual operations on clients or scripts are required to start data upload. |
About 1 day for 1 TB data with the bandwidth of 100 Mbit/s |
Data transmission is free. Only the storage space used on OBS is charged. |
Using CDM to Migrate Data (online) |
Less than 8 TB at a time |
Cloud Data Migration (CDM) must be subscribed to. |
One day for 1 TB to 8 TB (depending on the network condition and read and write performance of the data source) |
Fees are charged based on CDM instance specifications and the running duration. For details, see CDM Pricing Details. |
Using Disk-Based DES to Migrate Data (offline) |
Less than 30 TB at a time |
Users must prepare disks by themselves. |
For details, see How Long Does It Take to Migrate My Data to Huawei Cloud After I Have Created a DES Order? |
Fees are charged based on the number of disks and the running duration. For details, see DES Pricing Details. |
Using Teleport-Based DES to Migrate Data (offline) |
30 TB to 500 TB at a time |
Huawei data centers mail Teleports to users. |
For details, see How Long Does It Take to Migrate My Data to Huawei Cloud After I Have Created a DES Order? |
Fees are charged based on the number of disks and the running duration. For details, see DES Pricing Details. |
Using a Direct Connect Connection to Migrate Data (real-time) |
More than 100 TB data that needs real-time online transmission every month |
A Direct Connect connection must be deployed. |
Depends on the bandwidth of the Direct Connect connection. |
Fees are charged based on the distance and bandwidth of the connection. For details, see Direct Connect Pricing Details. |
