Basic Tuning
This section contains basic tuning information as it pertains to installation and configuration of the
hardware, operating system and Oracle8 server.
The Tuning sections of this paper which follow
contain information for tuning your DSS system.
Installation Issues
Flashable ROM
Apply the latest Compaq System ROMPaq and Option ROMPaq to the ProLiant Server.
Compaq System Configuration
During configuration of the ProLiant Server using the latest Compaq System Configuration
utility, several settings are recommended.
System
Primary Operating System = Windows NT version 4.0 or later
Specifies the Primary Operating System for initial configuration options.
Compaq Memory
Base Memory = 640 Kbytes, Linear
Contiguously maps all memory so that Compaq Built-In Memory is not available at FA0000,
but is instead added into extended memory.
The previously reserved memory area at FE0000 is
now available for use.
Array Configuration Utility
Controller Characteristics- Operating System = Windows NT 3.5x or later
This sets the drive geometry for the controller to be 32 sectors per track and the striping factor
to be 256 for RAID-0 and RAID-1.
The drive geometry for the controller is 32 sectors per track
and the striping factor is 32 for RAID-5.
Log Drives: Array Accelerator Status - Logical Drive # = Disabled
Non-Log Drives: Array Accelerator Status - Logical Drive # = Enabled
This increases performance of the controller by writing data to RAM on the controller instead
of directly to disk.
The RAM on the controller is mirrored and backed up by batteries for
increased reliability. The memory for the accelerator is either 4MB or 16MB, depending upon
the version of the controller board.
The accelerator cache can be configured at 100/0 percent,
75/25 percent, 50/50 percent, 25/75 percent or 0/100 percent for the amounts of memory that
will be reserved for the read-ahead/write-posting functionality of the accelerator.
