Figure A1-8.1 Platform Performance Baseline

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 A1-8.1 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 for platform sizing.


CPT Hardware tab

Figure A1-8.2 CPT Hardware tab provides a lookup table used by the CPT models to complete the capacity planning analysis
Figure A1-8.2 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 WATTs 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

Figure A1-8.3 HardwareSPEC Excel Workbook includes a snapshot copy of the vendor published SPEC Web Site benchmark values
Figure A1-8.3 provides a view of the HardwareSPEC workbook. The Esri Capacity Planning Tool release site shares a HardwareSPEC workbook with an Excel table of platform relative performance values from the published SPECrate_integer benchmarks.

The HardwareSPEC workbook contains a SRint2006 tab and an Amazon machine tab. All the new platform benchmarks are now published on the SPECrate_integer2006 site (SRint2006 tab). The last date the benchmark tab was updated is shown on the SPEC2006 tab. A hot link to the SPEC site is included on the top of the Capacity Planning Tool (CPT) hardware tab in column A.

The HardwareSPEC workbook tabs include an additional column (baseline/core) that I add to the 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 to comparing user display performance.

Adding a new platform to the CPT Hardware tab

Figure A1-8.4 CPT Hardware tab with a new Dell server added to the Project Platform Candidate lookup list
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 A-8.4 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.

Establishing business needs

Proper hardware selection depends on a clear understanding of your business needs. Figure A1-8.5 will show how to select the optimum platform for publishing ArcGIS 10.3 REST mapping services.

Figure A1-8.5 CPT Calculator tab configured for use in evaluating server platform candidates.

  • Single server direct connect platform architecture for evaluation purposes.
  • Large remote site with peak of 5 concurrent users, 6 Mbps network connection with 10 milliseconds latency.

Platform pricing analysis

Figure A1-8.6 Overview of the best buy hardware platform selection analysis.
Figure A1-8.6 provides an overview of the platform pricing analysis.

Hardware and Software pricing analysis

  • Hardware/virtual server pricing based on configured server provided by hardware vendor.
  • Software pricing based on number of cores provided by software vendor.
  • Total cost per core was computed to normalize pricing values.

Xeon E5-2697v3 platform has the lowest hardware cost per core without considering software pricing.

Warning: Selecting a server platform without evaluated what you need to satisfy your business requirements can lead to the wrong hardware selection.

CPT Web and ArcGIS for Server memory guidelines

Web and ArcGIS for Server memory guidelines are generated based on recommended peak active concurrent service instance (SOC) configurations supported by the selected platform configuration. The general guideline is 3 GB memory per server core. 3 GB memory would support up to 15 concurrent 100 MB active SOC service instances, well above the recommended target configuration of 3-5 active service instances per core for peak system throughput.

Warning: Sufficient memory must be available to support the peak number of active concurrent SOC processes. Additional memory may be required for GIS Server sites that support a high number of active concurrent SOC processes (more than 15 service instances per core)

Memory recommendations are provided on the CPT Calculator tab in cells I9 and I10, and on the CPT Design tab on each platform tier in column C. Average process size is provided on each tier in column P along with a cell to enter a custom process size if required.

CPT virtual server host platform memory guidelines
