For the performance analysis investigation, Novell and Compaq engineers used a standard benchmark tool to examine the following GroupWise Server system resource areas: • System Processor (CPU) Performance • Memory • Disk Subsystem • Bus Architecture (PCI versus EISA) • File Systems • Networking - Compaq ProLiant 5000 | Novell GroupWise Performance Management on Compaq Servers - Page 8

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 - Compaq ProLiant 5000 | Novell GroupWise Performance Management on Compaq Servers - Page 12

memory to load the volume; therefore, we strongly recommend using the services. You can improve the performance of your disk subsystem under load conditions by having your hardware logical drive span multiple physical drives using "striping." Striping allows the data to be written "across" a series - Compaq ProLiant 5000 | Novell GroupWise Performance Management on Compaq Servers - Page 14

With Compaq Smart-2 controller technology, this - Compaq ProLiant 5000 | Novell GroupWise Performance Management on Compaq Servers - Page 15
Array Accelerator has a read/write cache ratio that can be customized to fit your GroupWise Server activity using the Compaq Array Controller Configuration Utility. The configuration utility assigns 4 MB of cache memory to read/write operations. Ratios of 0% Read/100% Write, 25% Read/ 75% Write, 50 - Compaq ProLiant 5000 | Novell GroupWise Performance Management on Compaq Servers - Page 16

Novell GroupWise Performance
Management on Compaq Servers
This Compaq White Paper provides the results of a performance analysis conducted by
Novell and Compaq engineers on the GroupWise Server for Novell IntranetWare. The
information here is based on technical knowledge acquired by both Novell and Compaq
engineers while testing these products in a closely controlled environment.
This paper is for system integrators and network administrators with knowledge of
Compaq Server products, Novell GroupWise, and IntranetWare. It is a supplement to the
“Compaq Hardware Reference” document and the “Novell GroupWise 5.2”
documentation. The results and conclusions of this paper provide
•
an understanding of how Novell GroupWise works, including performance impact
with various hardware configurations.
•
suggestions for improving your GroupWise Server for IntranetWare performance.
•
recommendations for selecting the appropriate server hardware for your GroupWise
Server for IntranetWare.
