ECG007.0897 WHITE PAPER (cont.) 1...1 Memory Memory is one of the most valuable resources in a Novell NetWare server. Memory is used for both disk cache as well as program execution. The detail memory requirement for NetWare 4.1 server can be found in Novell Application Notes, January 1995. In that calculation, the administrator needs to take a number of variables into consideration such as Total Disk Capacity, Total Number of Clients, Volume Block size, and so on. GroupWise5 Memory Requirements: The memory requirements are upper limits for a high-usage messaging system. The memory required on a server for GroupWise 5.2 varies depending on many factors. This document should not be used as an absolute tool for calculating memory requirements. A GroupWise system will run with less than the maximum amount of memory required, but performance will be increased with additional memory. Memory amounts stated are for GroupWise and not total system memory. Factors that may cause variances in calculations and performance are: • Number of post offices and domains • Number of TCP Handlers and MF worker threads • Number of client/server connections being supported • Number of active client connections vs. idle connections • Message traffic between post offices and domains • Separate processors for POA, MTA and ADA • Dedicated Client/Server and MF worker processors • IP or direct connections between MTAs • High volumes of admin related traffic (user adds/deletes, NDS Sync, etc) • High volumes of large messages (i.e. large attachments, remote updates, etc.) Rule of Thumb for Memory Requirements The largest amount of memory for GroupWise 5.2 is used while running the Post Office Agent (POA.) The Message Transport Agent (MTA) and the Administrative Agent (ADA) have smaller requirements. For the POA, three main groupings determine the memory requirements: • Base memory for code, data and quick finder: 8,000,000 bytes • Number of TCP handlers & MF workers: n* 2,000,000 bytes • For C/S, number of concurrent connections: n* 50,000 bytes Recommendation of Memory Requirements The table below outlines the memory requirements for post offices with 100, 250, 500 and 1000 users. The memory requirements reflect the Post-Office Agent, Message Transport Agent and Administrative Agent. The memory requirements reflect peak usage at a time when all users are active. This information does not include requirements for the network operating system.
