32 Chapter 3 Server engineering guidelines213345.01Table 3 lists the server capacity options.CPU utilizationCPU utilization with all applications running and under peak traffic load must notexceed an average of 50%. In the event that CPU utilization exceeds this limit ona regular basis Nortel Networks recommends that you upgrade the server to onewith a higher CPU specification.MemorySufficient memory must be provisioned to minimize the amount of paging-to-diskactivities which has a detrimental impact on real-time performance.LAN traffic guidelinesThis section provides guidelines to provision basic LAN capacity for the differenttypes of messaging that occur in the TAPI environment.
