Does CBH Support Capacity Expansion?
Yes. For details, see Expanding CBH Instance Capacity. Before you start, pay attention to the following points:
- Before the expansion
To prevent data loss in case of an expansion failure, back up data in the mapped CBH system before the upgrade. For details, see How Do I Back Up CBH System Data?
Ensure that the current version of the CBH system is 3.2.16.0 or later if you want to upgrade the instance from standard to professional. Otherwise, the enhanced functions remain unavailable after the capacity expansion. If the CBH system version is earlier than 3.2.16.0, upgrade the system version first. For details about how to view the CBH system version, see About System.
- During the expansion
It takes about 30 minutes for capacity expansion. During this period, the CBH system is unavailable, but services running on the managed hosts are not affected. To avoid data loss, you are not advised to log in to the CBH instance for any operations during the expansion.
- After the expansion
Only data disks are expanded. Thus, system disks are not affected. After the capacity is expanded, the system expands the CPU, memory, and bandwidth for you, which does not affect the use of the original EIP.
