The 32-bit ChallengeThe 32-bit Challenge

Today, customers are experiencing unprecedented challenges in their computing environment

Increased complexity in mixed IT environmentsEver increasing user countsPower, 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 sizesDifficulty 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

32-bit Addressing32-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 4GBThis virtual address space is divided – system and user space, by default 2 GB eachThe 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 /USERVAAdd to boot.ini file and reboot to take effect

32-bit Systems With PAE And AWE32-bit Systems With PAE And AWE

PAE - Physical Address ExtensionAllows 36-bit memory addressingAllows the x86 processor to address up to 64GB of physical RAMAdd /PAE switch in the boot.ini file and reboot server

AWE – Address Windowing ExtensionAWE – a set of APIs that allow programs to address memory locations outside of their 4GB virtual addressing rangeWith 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

Performance Implications Of 32-bit MemoryPerformance 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 slower32-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 connectionsSQL Server connections are lightweight, so 4,000+ connections are possible, even with limited memory

Both CPU affinities and thread priorities can be set and manipulated via registry parameters on a thread-by-thread basisUser-thread support

Users may now run the database in user-thread mode, which employs database-scheduled fibers instead of O/S scheduled threadsFor CPU intensive apps, this will provide a performance boost and reduce CPU utilization

• x64 for mainstream / commodity• Competes against existing high-end x86 platforms• Targets servers using up to 4p/8core• Pricing not significantly greater than traditional x86 based

systems• Based on 64-bit Extension to the x86 instruction set

• Itanium for scale-up• Optimized for most demanding DB & LOB workloads• Targets servers using 4 -128* processors• Scalable up to 128* processors and 2 terabyte of physical

memory• Pricing more competitive to x64 and x86 systems, and

price/performance comparable to x86 and x64• Based on EPIC (Explicitly Parallel Instruction Computing)
