You can set up a stateful failover system on one CVM platform. Setting up a stateful failover system might take a long time, because the local and peer disk partitions must be initialized during the setup process. The time it takes to set up a stateful failover system depends on the disk size and network speed. For example, it requires about 20 minutes to initialize 100 GB of disk space over a Gigabit network, and using a 10 Gigabit network can speed up initialization.
