VMware Data Services Manager supports MySQL and PostgreSQL databases, open-source relational database management systems (RDBMS).
VMware Data Services Manager supports multiple database versions of PostgreSQL and MySQL.
For information about supported versions, see Hardware and Software Requirements.
You can create, edit, manage, and monitor databases in VMware Data Services Manager. You can also clone, recover, and restore databases.
Database Clusters
VMware Data Services Manager supports PostgreSQL database clusters. Database clusters promote redundancy and help in business continuity. A database cluster that consists of a Primary database and one or more Replica databases enables manual and automatic promotion of a Replica database if and when a Primary becomes unavalilable.
Note: VMware Data Services Manager does not support replicas for MySQL.
