Novell Doc: GroupWise 7 Installation Guide - Agent System Requirements

7.2 Agent System Requirements

32-bit/x86 processor or 64-bit/x86 processor
Any of the following server operating systems for the POA and the MTA:
- Novell Open Enterprise Server 1 or Open Enterprise Server 2 (NetWare or Linux version), plus the latest Support Pack
- NetWare 5.1, NetWare 6.0, or NetWare 6.5, plus the latest Support Pack for your version of NetWare
- SUSE® Linux Enterprise Server 9 or SUSE Linux Enterprise Server 10, plus the latest Support Pack
  
  The X Window System is required by the GUI GroupWise Installation program. A text-based Installation program is also available.
  
  The X Window System and Open Motif are required by the GUI GroupWise agent server consoles. By default, the agents run as daemons without user interfaces.
- Windows Server 2000 or Windows Server 2003, plus the latest Service Pack for your version of Windows
Adequate server memory as required by the operating system
Approximately 25 MB for the agent software (varies by platform)

The amount of memory actually used by the POA depends on the number of active users, as illustrated by the table below:

Table 7-1 Memory Usage Examples

Concurrent Users	Actual Memory Usage at Peak Time
100 active users (100-250 users in post office)	80 MB
250 active users (250-500 users in post office)	160 MB
500 active users (500-1000 users in post office)	250 MB
1000 active users (1000-2500 users in post office)	500 MB

The POA typically performs best with abundant cache memory available. On the server where it runs, at least 2 GB of memory is recommended.
