COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
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 Compaq System Configuration Utility, do
not select mirroring while using INSTALL.NLM. The fault tolerance
capabilities of the Smart Array 3200 Controller provide performance
improvements and automatic data recovery features.
■ Novell recommends that you create volumes with a 64-KB block size
and that you use 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.
■ Use of linear memory provides the best performance in the NetWare
environment. When you use the Compaq System Configuration Utility to
configure your server with NetWare, the memory options default so that
linear memory is used. To verify the setting, run the Compaq System
Configuration Utility and view the Compaq Memory settings. Make sure
that a linear option has been selected under the Base Memory option.
Using the Compaq Drive Array Optimization
Utility (CPQDAOPT)
Compaq recommends that you use the Compaq Drive Array Optimization
Utility (CPQDAOPT.NLM) to optimize the drive arrays on your server before
creating partitions. CPQDAOPT assists you in optimizing performance and can
increase drive array performance by 20 to 40 percent. CPQDAOPT provides a
formula specific to your configuration. Use this information as you create a
partition using INSTALL.NLM. If you installed NetWare using SmartStart, it is
not necessary to run this utility.
