8. The 32-bit Challenge Today, customers are experiencing unprecedented challenges in their computing environment Increased complexity in mixed IT environments Ever increasing user counts Power, space and heat restrictions It is becoming increasingly difficult to sustain Mission- Critical databases on 32-bit architectures Difficulty in scaling to handle increasing database sizes Difficulty in managing large concurrent user counts There is a limited future for 32-bit processors, 32-bit Operating Systems, and 32 bit databases All current and future hardware and software development is oriented towards 64-bit platforms Today, customers are experiencing unprecedented challenges in their computing environment Increased complexity in mixed IT environments Ever increasing user counts Power, space and heat restrictions It is becoming increasingly difficult to sustain Mission- Critical databases on 32-bit architectures Difficulty in scaling to handle increasing database sizes Difficulty in managing large concurrent user counts There is a limited future for 32-bit processors, 32-bit Operating Systems, and 32 bit databases All current and future hardware and software development is oriented towards 64-bit platforms

9. 32-bit Addressing 32-bit processors have address registers that are 32-bits wide (can address up to 4GB RAM) Each individual process gets its own virtual address space that can be up to 4GB This virtual address space is divided – system and user space, by default 2 GB each The user space can be extended to 3 GB with the 4 GB Tuning feature /3GB flag = 4GB Tuning Feature – reduces system space to 1GB, allowing 3GB for user space – also /USERVA Add to boot.ini file and reboot to take effect 32-bit processors have address registers that are 32-bits wide (can address up to 4GB RAM) Each individual process gets its own virtual address space that can be up to 4GB This virtual address space is divided – system and user space, by default 2 GB each The user space can be extended to 3 GB with the 4 GB Tuning feature /3GB flag = 4GB Tuning Feature – reduces system space to 1GB, allowing 3GB for user space – also /USERVA Add to boot.ini file and reboot to take effect

10. 32-bit Systems With PAE And AWE PAE - Physical Address Extension Allows 36-bit memory addressing Allows the x86 processor to address up to 64GB of physical RAM Add /PAE switch in the boot.ini file and reboot server AWE – Address Windowing Extension AWE – a set of APIs that allow programs to address memory locations outside of their 4GB virtual addressing range With AWE programs reserve memory as non-paged (will not page out) These methods add a translation layer to memory access – slower than direct memory access PAE - Physical Address Extension Allows 36-bit memory addressing Allows the x86 processor to address up to 64GB of physical RAM Add /PAE switch in the boot.ini file and reboot server AWE – Address Windowing Extension AWE – a set of APIs that allow programs to address memory locations outside of their 4GB virtual addressing range With AWE programs reserve memory as non-paged (will not page out) These methods add a translation layer to memory access – slower than direct memory access

11. Performance Implications Of 32-bit Memory Memory split into two parts is not as efficient as memory in one segment Overhead is introduced, memory access is substantially slower 32-bit systems with 8 GB of RAM may not perform much better than systems with 4 GB of RAM Memory above 4 GB can only be used for Buffer cache Buffer cache does not support user connections; all user connections must be supported from low memory (<= 3GB) AWE overhead may take up an additional 1 GB of low memory, leaving only 1-2 GB for managing user connections SQL Server connections are lightweight, so 4,000+ connections are possible, even with limited memory Memory split into two parts is not as efficient as memory in one segment Overhead is introduced, memory access is substantially slower 32-bit systems with 8 GB of RAM may not perform much better than systems with 4 GB of RAM Memory above 4 GB can only be used for Buffer cache Buffer cache does not support user connections; all user connections must be supported from low memory (<= 3GB) AWE overhead may take up an additional 1 GB of low memory, leaving only 1-2 GB for managing user connections SQL Server connections are lightweight, so 4,000+ connections are possible, even with limited memory
