files stored on the volume, or the application you used, you can increase or decrease the volume block size to improve the performance. The Novell/Compaq test team found that setting the volume block size to 64 KB yields the best result. The following graph shows the performance comparison. - Compaq 307560-001 | Novell GroupWise Performance Management on Compaq Servers - Page 13

You can improve the performance of your disk subsystem under load conditions by having your hardware logical drive span multiple physical drives - Compaq 307560-001 | Novell GroupWise Performance Management on Compaq Servers - Page 14

Read/Write Ratio The 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 - Compaq 307560-001 | Novell GroupWise Performance Management on Compaq Servers - Page 16

This improvement in performance can be explained by the additional read-related , the networking subsystem is less likely to cause performance problems than the subsystem areas previously discussed.

To compare and evaluate 10-Mb/s Ethernet and 100-Mb/s Ethernet, parallel test environments were set up in the integration testing labs at Compaq. The results, shown in Table 3, compare a 10-Mb/s Ethernet LAN with that of a 100-Mb/s Ethernet LAN.

For added reliability, the ProLiant 5000 offers support for redundant 10/100 TX PCI UTP Network Interface Controllers (NICs - Compaq 307560-001 | Novell GroupWise Performance Management on Compaq Servers - Page 20

the system performance is the Read Ahead Cache which is the amount of memory allocated to the GroupWise Server specified in bytes. Novell and Compaq engineers recommend using the default read-ahead cache due to the 15-20% performance gain show in the following figure.

The recommendation is to use numerous smaller drives in an array rather - Compaq 307560-001 | Novell GroupWise Performance Management on Compaq Servers - Page 23
in the array, the lower portion of each drive reserved for fault tolerance support. Set the Smart Array Controller read/write ratio to an appropriate level. In ProLiant 5000 can sustain 1000 users. These tests prove that Compaq is a viable solution for GroupWise needs. More detailed information

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.
