Platform Performance (CPT Demos) 43rd Edition

Arc18CapacityPlanning0901 release

Selecting the right hardware will improve user performance, reduce overall system cost, and establish a foundation for building effective GIS operations. Selecting the wrong hardware can contribute to implementation failure - spending money on a system that will not support your business needs. Figure A1-7.1 shows the changes in platform performance over the past 10 years.

This section will introduce the CPT Hardware tab, use the CPT to evaluate hardware platform best buy decision, and use the CPT Platform Capacity Calculator and CPT Calculator tab for platform sizing. 

CPT Hardware tab
Figure A1-7.2 shows the CPT Hardware tab that includes a list of Desktop and Server SPEC CPU platform benchmark baseline values used as a lookup table by the CPT Calculator, Design, Test, and Favorites tabs. The SPEC benchmark values are used to adjust baseline service times to selected platform service times for capacity planning analysis.

Published vendor benchmark values are used to identify relative throughput and performance for selected hardware platforms. Platforms are arranged by vendor and year in two lookup lists. Desktop candidates are located at the top of the list. Server candidates are located at the bottom of the list. Project platform candidates are located in the middle of the list and included with the Desktop and Server list selections.

Primary platform values are entered in the WHITE cells (Processor, # of Cores, Core/Chip, MHz, SPECint_rate2006 baseline). COLORED cell values are generated from the WHITE cell entries (Hardware Platform Selection, Per core SPECint_rate2006 value, Total chips). Additional columns include vendor and processor WATT information.

The SPEC Web site is the primary source for the platform performance metrics. Information from the SPEC Web site is entered into the CPT Hardware tab for capacity planning. Copy of the SPEC benchmark information is provided in a HardwareSPEC Excel workbook for easy access. 

HardwareSPEC Excel Workbook
The Esri Capacity Planning Tool release site shares a HWSPEC workbook with an Excel table of platform relative performance values from published SPECinteger_rate benchmarks. The HardwareSPEC (HWSPEC) workbook contains a SPEC2006 tab and a SPEC2017 tab. Relative performance of older platforms are published by hardware vendors on the SPECint_rate2006 benchmark site. Relative performance of newer platforms are published by hardware vendors on the SPECint_rate2017 benchmark site. The date the performance benchmarks are captured from the SPEC Web site is shown on each of the HWSPEC tabs. A hot link to the SPEC site is included on the top of the Capacity Planning Tool (CPT) hardware tab in column A.

SPECint_rate2017 benchmarks
Figure A1-7.3 provides a view of the HWSPEC SPEC2017 benchmark tab. Hardware vendors complete the SPEC2017 performance benchmarks for new platform releases and publish results on the SPECint_rate2017 web site. The SPEC2017 benchmark values are downloaded and included in an excel table in the HWSPEC SPEC2017 tab. The HWSPEC SPEC2017 tab also includes additional columns sharing the SPECint_rate2006 values provided by a lookup from the HWSPEC SPEC2006 tab. 

SPECint_rate2006 benchmarks
Figure A1-7.3 shares a view of the HWSPEC workbook SPEC2006 benchmark tab. Hardware vendors SPEC2006 performance benchmarks are available for older platform releases shared on the SPECint_rate2006 web site. The SPEC2006 benchmark values are downloaded and included in an excel table in the HWSPEC SPEC2006 tab. The HWSPEC SPEC2006 tab also includes additional columns sharing the SPECint_rate2017 values provided by a lookup from the HWSPEC SPEC2017 tab. For capacity planning purposes, all of the SPEC published relative platform performance metrics are combined and shared on the SPEC2006 tab.

HWSPEC workbook tabs include an additional column (baseline/core) included with each table. This column identifies the processing performance of an individual core, a value that is used to estimate relative platform processing performance for a single sequential display (estimate of the relative platform speed). The relative processing performance per core values will be used in this chapter for comparing user display performance and adjusting user productivity during peak loads. 

Adding a new platform to the CPT Hardware tab
New hardware platform benchmark values are published on the SPEC Web site each month throughout the year, so the platform you need for your design analysis may not be included in your version of the CPT. You can locate the new benchmark values on the SPEC Web site and then add them to your CPT Hardware tab.

Figure A1-7.4 highlights the entries you will need to make to the CPT Hardware tab.

To add a new Server to the CPT Hardware tab, first create a new row template by copying one of the existing Platform rows and Insert Copied Cells to create a new row in the Project Platform Candidate section. Enter the processor name, # of Cores, Core/Chip, MHz, and the SPECint_rate2006 baseline value for the new server (Type new entries in the white cells only). The colored cells include formulas and will be completed as you enter the new values in the white cells.

Once you have completed your entries, the new server will be available for selection in all CPT Platform Selection dropdown lists. 

CPT used to evaluate best buy
CPT is designed to automate the system architecture design analysis. The system architecture design analysis translates user business requirements to appropriate hardware platform solutions. Once you know your business requirements, the CPT can be used to identify your optimum platform selection.
