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.

Multi-site model

The multi-site model can be used in organizations where WAN links are high speed and low utilization and the remote connected sites have 100 or fewer users.

To lower the bandwidth requirements even further from the default installation, Archive Manager can be configured to ‘Dataload’ email messages from the remote sites at preset times of the day.

If the remote sites already have email servers, the servers should be set up to journal locally in order to minimize bandwidth usage of the journaling process. In these cases, the Archive Manager Dataloader can be configured to retrieve the journaled messages from those sites overnight, thereby spreading network traffic over 24 hours instead of eight working hours.

Archive Manager provides the option of installing the Organizational form for ‘Stubbed’ messages. By not installing the form for Microsoft Outlook, the bandwidth requirements of Archive Manager are reduced further as email is not retrieved from the Archive Manager database when browsed via Microsoft Outlook; the email is retrieved only when a link in the message is selected.
