Hi, Dear sir Jon,

Thank you very much for your kindly replying and guiding.
And now I know a way to use mysql-cluster to build two geographical data centers.

And my other question is: since, mysql-cluster's data node's heartbeat
permits max time upto around 49 days, otherwise it is going to declare cluster dead, and nowaday's two cities' network is not so slow as over 1 days, then is it possible for me to build only one geographical data center by using mysql-cluster, which's data nodes',management nodes and SQL nodes are located in different cities?

That is: is it possible for me to build only one mysql-cluster' data center whose data nodes are located in several faraway cities? such as:two data nodes in a same city but two other data nodes in other same city, and the cluter's-first-dead-related data-node's heartbeat between two cities are set to as long as enough for data nodes' communication? since
a four data nodes cluster permits only 2 data nodes up to survive.

Many thanks to Jon's teaching!

Best regards,
0086-156 6865 8383 or 0086 180 500 42436
