Fat Vs. Ntfs; Compaq System Configuration Utility Considerations - Compaq 117755-003 - ProSignia - 740 Configuration Manual

Configuration and Tuning of Sybase System 11 for Microsoft Windows NT on Compaq Servers
Y
Reliability and recovery procedures are very similar to those of Windows NT fault tolerance.
Your system remains running, but you will have to take the system off-line and upon a failed
drive replacement you will have to manually remirror the devices.
Y
Again, mirroring through Sybase SQL Server induces an additional processing overhead on
the system, resulting in a lower performance.

FAT vs. NTFS

Our testing showed only a slight difference in performance between FAT and NTFS file systems
in a Sybase SQL Server environment. It is recommended that NTFS be used for both transaction
log and database files for optimal performance, ease of disk management and data recoverability.
Be aware that the Windows NT C2-level security features are only available on NTFS volumes.
A complete list of advantages and disadvantages of FAT and NTFS file systems is available in
the Microsoft Windows NT, Concepts and Planning Guide.

Compaq System Configuration Utility Considerations

Compaq System Configuration
SMART and SMART-2 SCSI Array controller. This selection allows the configuration utility to
choose the best physical characteristics, such as striping block size, number of sectors per track,
etc., for a given environment.
Once you choose the MS Windows NT option as your selection for the operating system, you will
be presented with the following options:
Y
MS Windows NT 3.1

Choose this option only if you're running Microsoft Windows NT version 3.1.
Y
MS Windows NT 3.5x

This option provides with best performance under Microsoft Windows NT version 3.5x.
Y
MS Windows NT 3.5x - Maximum Boot Size

This option provides you with maximum boot partition size available under Microsoft
Windows NT version 3.5x. The partition limitations outlined below still apply.
WARNING:
Compaq System Configuration utility causes the controller to apply different physical
characteristics to the drive array. As a result, you may lose data on such a drive array. If you
have existing data on such a drive array, and need to change these controller characteristics, we
strongly suggest you back up your data completely before doing so.
Current partition limitations are as follows:
Y
Windows NT 3.5x limit the boot partition to 4GB, regardless of the file system.
