EMS uses a relational database to store device and application
information and present it to system users through the GUI and CLI
clients. When you initially discover devices, EMS populates the database;
therefore, this allows you to manage each device and its associated MIB
attributes without having to rediscover each device. You can also view
real-time events and traps which are logged to the database.
There are two database configuration options available for you to use:
Embedded Database
■
database within EMS. EMS uses this database by default. Embedded
databases are used primarily for smaller deployments.
External Database
■
larger deployments. You can either install the external database on the
EMS server itself or on a dedicated external database server. Before
installing the external database, review the minimum hardware
requirements. For a list of those requirements, see

The internal embedded database is not compatible with Server Failover .
If you wish to use Server Failover you will need to use an external
database.
