[detailed description of the problem]

Can a cluster install two SAC at the same time?

[solution]

1. Yes, but it is usually a SAC

2. When you install multiple SAC in a cluster, you need to take special care. If there are machines An and B, you can first deploy the cluster on A with SAC, including the nodes on machine B. Then the cluster is found on the SAC of machine B. This allows you to access the same cluster on both SAC.

[solution]

1. Yes, but it is usually a SAC, and a SAC can manage all real instances in the sdb cluster as well as all pgsql and mysql instances

2. You can install multiple SAC in a cluster, but it is not recommended. If you need to install more than one SAC, you need to do special care. If there are machines An and B, you can first deploy the cluster on A with SAC, including nodes on machine B. Then the cluster is found on the SAC of machine B. This allows you to access the same cluster on both SAC.
