What Are the Differences Between OMS and MgC in Storage Migration?

Positioning |
OMS is an online data migration service. It is used to migrate data from object storage services of other cloud service providers to Object Storage Service (OBS) of Huawei Cloud. |
MgC is a one-stop migration platform. MgC migration workflows support not only object storage migration, but also file storage migration. It also provides standard workflow templates tailored to different migration scenarios. |
Migration performance |
Generally, OMS can migrate 10 TB to 20 TB of data per day. It allows you to create migration task groups for large-capacity and large-scale object migration to maximize concurrency performance. A maximum of five concurrent migration tasks are allowed for you in a single region. |
MgC allows you to migrate data using dedicated, scalable migration clusters and up to 20 Gbit/s of bandwidth. You can specify the number of concurrent subtasks in a storage migration workflow in MgC based on the number of online migration nodes. There cannot be more than 10 concurrent subtasks for each online migration node. |
Migration speed |
Shared resources, bandwidth, and quotas limit the migration speed to 500 Mbit/s. |
Migration speed is influenced by both the available migration bandwidth and the IOPS performance of the source and target storage systems. The maximum migration speed is calculated by multiplying the migration speed of a single node by the total number of nodes. |

You need to pay for the migration cluster resources used. For example, you use a migration cluster that consists of one master node, N list nodes, and N migration nodes. |
