Parameter

Application Server

Mediation Server

Database Server

Clients

Add Application Servers if there will be more than 10 combined Java clients and Mediation Servers.

Distribute the Mediation Server if there are more than 5 Java clients.

 

Routers

 

As a general rule, distribute the Mediation Server when the number of large routers exceeds 50.

 

As a general rule, add Mediation Servers when the number of large routers exceeds 75.

 

Traps (Includes Syslog Messages that Generate Events in Redcell)

 

Distribute the Mediation Server if sustainable traps will exceed 100 per second.

 

Add Mediation Servers if sustainable traps will exceed 200 per second.

High volumes of inserts and deletes demand more database performance as event rates increase.

Syslog Messages (Total Received)

 

Use a dedicated Mediation Server for collection of more than 2,500 syslog messages per second. Add an additional Mediation Server when syslog messages exceed 10,000 per second.

 

Performance Data

 

Use a dedicated Mediation Server for collection of performance data.

Use a separate database server for storing performance data.

Physical Location

 

Distribute the Mediation Server if the managed devices are remote. The Mediation Servers should be located as close to the managed devices as possible, preferably in the same subnet.

 

Resynchronization

The processing requirements for resynchronization of a device are highly variable and depend on a number of factors including the model, protocol, and the number of ports and interfaces. Add Application Servers if there are a large number of subcomponents per device, especially virtual routers and subinterfaces.

The time required to resynchronize a device varies, depending on a number of factors including the model, protocol, and the number of ports and interfaces. Add Mediation Servers if a large number of subcomponents per device exist, especially virtual routers and subinterfaces.

 

Backup and Restoration

Uses disk space for temporary storage of configuration files. The processing requirements for configuration file backup depend on the size of the file. Add Application Servers and/or reduce the number of devices in a group for scheduled backups when the configuration files are large.

Uses disk space for temporary storage of configuration files.

Uses disk space for storage of configuration files.

Firmware Deployment

Uses disk space for temporary storage of firmware.

Uses disk space for temporary storage of firmware.

Uses disk space for storage of firmware.

Group Operations

 

The Mediation Server should be distributed if Group Operations are performed on many devices.

 

Service Applications

Large VPNs, especially Mesh VPNs, affect Application Server performance. The impact of MPLS Manager and Policy Manager is less than VPN Service Center.

Large VPNs, especially Mesh VPNs, affect Mediation Server performance. The impact of MPLS Manager and Policy Manager is less than VPN Service Center.

VPN Service Center uses significant database disk space for storage of large, complex VPNs. The impact of MPLS Manager and Policy Manager is less than VPN Service Center.

Session-Based Load Balancing

Cluster Application Servers for session-based load balancing.

 

 

High Availability

Clustering eliminates single point of failure for Application Servers.

Use paired Mediation Servers to eliminate single point of failure.

Use Oracle Real Application Clusters (RAC) for database replication, synchronization and fail-over.

Hard drive space requirements listed here, and other hardware requirements are based on expected maximum use for average installations and are only intended to be an approximate guide.

[spacer]

For production systems, Oracle must be on its own server. See also Oracle Version Support for more about hardware requirements for an Oracle installation.

[spacer]

Size your database server’s disk based on anticipated traffic. Oracle's archive logs can grow rapidly. (In one test these archive logs grew to 12 GB in two weeks). If the file system fills up with the archives, Oracle stops, and may need to be restarted to clear an archive error.

[spacer]

Also: Ensure that your database, whether embedded or Oracle, resides on a separate disk, not just a separate partition.
