Galera cluster maria DB

Question

What will be the best practice to deploy Gallera cluster having two physical servers (Server A and Server B).

first Option

1. Galera Arbitrator (Where it should be configured in A or B or in any other system)

2. Can i have like one DB node 1 in server A and the other two DB nodes 2,3 in Server B.

Will the cluster works if the server B goes down with both node 2,3 unavailable.

Answer 1

＆＃34;最佳＆＃34;是为3个物理服务器提供三个个不同的位置。 （一个可能是garbd。）

如果将两个节点（常规和/或garbd）放在同一个物理位置，则很容易受到地震，飓风，洪水等的影响。
