Novell NetWare 6 performance tuning guidelines for ProLiant servers

tips and tricks

Use the following tips to improve the performance of your disk subsystems:
If the number of dirty buffers remains constant and the number of current disk
requests remains high, the disk subsystem might be a bottleneck. Consider installing a
faster disk drive and a controller.
If the number of dirty buffers is frequently above 50% of total cache buffers, add
more memory for cache.
Monitor the swap activities (listed in table 5) taking place. To view the swap file,
type the following console command:
table 5. virtual memory swap file (sizes in millions of bytes)
volume name: SYS
swap file
size: 22
used: 0
min: 2
max: 4116
Summary
total swap file
size: 22
used: 0
min: 2
max: 4116
If necessary, create a swap file (one per volume) by typing the following console
command:
SWAP ADD SYS1 MIN=4, MAX=8, MIN FREE=3000
MIN = minimum swap file size (default = 2)
MAX = maximum swap file (default = free volume space)
MIN FREE = minimum free space to be preserved on a volume outside the swap file
(default = 5).
To remove a swap partition, type the following console command:
The Swap file is a storage location for data moved to the disk by the virtual memory
manager. To monitor Swap file activities using the NRM tool, follow these steps:
1. Open the NRM and select View Memory Config listed under the Manage Server
category.
Note: For detailed instructions on how to invoke the NRM, refer to the NetWare
Remote Manager section of this document.
