Archive Manager 5.9.3 - SDK Guide

Extended properties

Certain message types may contain extended properties and can be added to the message SourceProperties property. For example, we can add the property “Task.StartTime” to the message. These extended properties require special formatting and encoding. A method was provided at the instance level to attach the properties to a message.

IMessage message = new Message();
MessageSourceProperties messageProperties = new MessageSourceProperties();
messageProperties.Add(new MessageSourceProperty("Task.StartTime", DateTime.Now, SourcePropDataType.DateTime));
archiveManager.EncodeSourceProperties(messageProperties, message);

Deployment models

Several different deployment options are available for Archive Manager, depending on organization size and type. The following information can be used to determine a basic specification for an Archive Manager solution, although each organization must be assessed for its own unique qualities and needs.

When estimating a configuration for a site, it is important to know:

•
The number of sites and the number of users at each site
•
The number of mail servers
•
The bandwidth between each site

Single-site model

The single-site model is suitable for single-site organizations as well as for organizations with high-speed and low-use WAN connections.

Hardware sizing can be roughly estimated from the number of users. For detailed recommendations, see the Hardware recommendations chapter of this guide.

Sizing is also affected by the Archive Manager message policies applied to Exchange after Archive Manager is implemented. Specifically, hardware requirements will increase if messages are kept on the mail server for only short periods (for example, <15 days), since users will access the Archive Manager system far more extensively than if messages are kept 30 or 60 days.

* 
NOTE: Large organizations and sites with comprehensive disaster recovery (DR) requirements need to consider clustering Microsoft SQL Server and Internet Information Services (IIS) if the archived information is deemed critical to the organization. The information within Archive Manager is a copy of current information and possibly all email information outside of the configured retention policy period; this may affect the requirements.
