ECG007.0897 WHITE PAPER (cont.) 2...2 PERFORMANCE CONCLUSIONS This section presents conclusions and recommendations for performance management, based on the performance tests and data analysis carried out by Novell and Compaq engineers. System Processor Research clearly shows that the CPU was found to be the most important server subsystem affecting overall system performance of the GroupWise Server. The conclusion is that the faster the processor, the better the performance gains for the system. Therefore, Novell and Compaq engineers recommend the fastest processor that can be purchased within the budgetary limitations of your project. Furthermore, the performance of the Pentium Pro Processor clearly shows that its superior features help contribute to the improvement in performance over the Pentium Processor rated at the same clock speed. Memory In addition to the IntranetWare's memory requirement, please add the following memory to the system total memory: Table 5.

The recommendation is to use numerous smaller drives in an array rather than a few larger drives to achieve the best overall system performance providing comparable storage capacities. Hardware striping is recommended due to performance gains, as well as more system resource efficiencies than when using software striping. Hardware striping is achieved by Compaq's Smart-2 Array Controller, which also has built-in data protection features, adding another benefit over software striping.

ONCLUSIONS
This section presents conclusions and recommendations for performance management, based on
the performance tests and data analysis carried out by Novell and Compaq engineers.
System Processor
Research clearly shows that the CPU was found to be the most important server subsystem
affecting overall system performance of the GroupWise Server. The conclusion is that the faster
the processor, the better the performance gains for the system. Therefore, Novell and Compaq
engineers recommend the fastest processor that can be purchased within the budgetary limitations
of your project. Furthermore, the performance of the Pentium Pro Processor clearly shows that its
superior features help contribute to the improvement in performance over the Pentium Processor
rated at the same clock speed.
Memory
In addition to the IntranetWare’s memory requirement, please add the following memory to the
system total memory:

Disk Subsystem
Novell and Compaq engineers recommend disk striping to benefit from the gain in I/O
performance. The recommendation is to use numerous smaller drives in an array rather than a
few larger drives to achieve the best overall system performance providing comparable storage
capacities.
Hardware striping is recommended due to performance gains, as well as more system resource
efficiencies than when using software striping. Hardware striping is achieved by Compaq’s
Smart-2 Array Controller, which also has built-in data protection features, adding another benefit
over software striping.
