Optimizing Array Controller Performance

To improve system performance, keep these tips in mind before creating NetWare
volumes or partitions:

• If you selected a fault-tolerance option, such as mirroring or distributed data

guarding, when using the System Configuration Utility, do not select mirroring
while using INSTALL.NLM. The fault-tolerance capabilities of the MSA500
controller provide performance improvements and automatic data recovery
features.

• Novell recommends creating volumes with a 64-KB block size and using the

Block Sub-Allocation feature of NetWare. Using a large block size decreases the
amount of RAM required to mount the volume, while Block Sub-Allocation
allows NetWare to allocate disk space more efficiently.
