Storage Engine Architectural Overview

The original code was inherited from Sybase and designed for eight-megabyte Unix systems in 1983.These new formats improve manageability and scalability and allow the server to easily scale from low-end to high-end systems, improving performance and manageability.
There are many benefits of the new on-disk layout, including:
• Improved scalability and integration with Windows NT Server
• Better performance with larger I/Os
• Stable record locators allow more indexes
• More indexes speed decision support queries
• Simpler data structures provide better quality
• Greater extensibility, so that subsequent releases will have a cleaner development process and new features are faster to implement
