Claims
- 1. A system for selecting configurations of computer components, comprising:
a general purpose computer executing application software; a configuration sizer tool that provides a user interface to determine a system configuration for a particular class of computer product in response to user performance and requirement specifications; and a price-performance module in the configuration sizer tool that evaluates the performance of candidate system configuration and normalizes to the price for the system configuration.
- 2. The system of claim 1, wherein the price-performance module determines performance based on response time estimates.
- 3. The system of claim 2, wherein the response time estimates are based upon processor latency added to the time to perform a database read times the number of physical database reads per transaction.
- 4. The system of claim 3, wherein processor latency is calculated dependent upon queue length, processor service time, and number of central processing units (CPUs).
- 5. The system of claim 4, wherein the latency is determined by the equations:
- 6. The system of claim 5, wherein processor service time is determined based on the number of physical reads, logical reads, and physical writes per transaction according to the following equations:
- 7. The system of claim 6, wherein the cache hit ratio is determined by the following equation:
- 8. The system of claim 5, wherein processor utilization is estimated based upon multiplying the transaction processor time by the transaction rate as determined by the equation:
- 9. The system of claim 3, wherein the time to perform a database read is calculated according to the following equations:
- 10. The system of claim 1, wherein the configuration sizer tool includes a configuration sizer and a configuration sizer framework.
- 11. The system of claim 10, wherein the configuration sizer is specific to an SQL server.
- 12. The system of claim 1, wherein the price and performance characteristics for candidate system configurations are provided in hardware definition files.
- 13. A method of selecting system configuration comprising the steps of:
providing a configuration sizer tool to develop recommended configurations for a class of products in response to performance and requirement specifications from a user; calculating performance characteristics for candidate systems that satisfy the required performance and requirement specifications of the user; normalizing the performance characteristics to system price; and displaying the candidate systems to the user in order of normalized price/performance.
- 14. Computer executable code stored on machine readable media for selecting configurations of computer components, the computer executable code comprising:
a configuration sizer tool that provides a user interface to determine a system configuration for a particular class of computer product in response to user performance and requirement specifications; and a price-performance module in the configuration sizer tool that evaluates the performance of candidate system configuration and normalizes to the price for the system configuration.
- 15. The computer executable code of claim 14, wherein the price-performance module determines performance based on response time estimates.
- 16. The computer executable code of claim 15, wherein the response time estimates are based upon processor latency added to the time to perform a database read times the number of physical database reads per transaction.
- 17. The computer executable code of claim 16, wherein processor latency is calculated dependent upon queue length, processor service time, and number of central processing units (CPUs).
- 18. The computer executable code of claim 17, wherein the latency is determined by the equations:
- 19. The computer executable code of claim 18, wherein processor service time is determined based on the number of physical reads, logical reads, and physical writes per transaction according to the following equations:
- 20. The computer executable code of claim 19, wherein the cache hit ratio is determined by the following equation:
- 21. The computer executable code of claim 18, wherein processor utilization is estimated based upon multiplying the transaction processor time by the transaction rate as determined by the equation:
- 22. The computer executable code of claim 16, wherein the time to perform a database read is calculated according to the following equations:
- 23. The computer executable code of claim 14, wherein the configuration sizer tool includes a configuration sizer and a configuration sizer framework.
- 24. The computer executable code of claim 23, wherein the configuration sizer is specific to an SQL server.
- 25. The computer executable code of claim 14, wherein the price and performance characteristics for candidate system configurations are provided in hardware definition files.
