City of Rome Year 1 (CPT Demos) 40th Edition

Arc17CapacityPlanning0701 release

This section shares the CPT analysis supporting the City of Rome Year 1 system architecture design. The City of Rome case study brings together what has been discussed in the earlier chapters and demonstrates the value of the system design analysis in making informed design decisions.

Pre-design efforts
Figure 11.2 shows the efforts completed in preparation for the system design. Business needs must be understood before you are ready to complete the system design.

Business needs analysis
 * Enterprise vision. Have a clear vision and long term goal for enterprise GIS operations.
 * Existing Business Architecture. Understand how the business works and what technology is being used to support operations.
 * Workflow loads analysis. Review the business processes to identify where and what is required to support business needs.

City of Rome is planning to implement an ArcGIS Enterprise initial operational capability to enhance their current operations. Following the ArcGIS Enterprise deployment, the City will leverage the ArcGIS Water Solutions maps and apps to enhance City water utility operations.

Phase 1 of the case study will implement an ArcGIS Enterprise solution with the existing business environment.
 * Model the existing City of Rome operations
 * ArcGIS Enterprise IOC architecture
 * Vector tile basemap architecture
 * Citrix host hardware platform upgrade
 * ArcGIS Enterprise hardware upgrade baseline

Phase 2 will implement a Water Utility solution for City of Rome
 * Water solutions user needs analysis
 * Water solutions system design

"Best practice: CPT will be used to complete the system design analysis."





Phase 1: City of Rome existing operations


CPT Workflow Loads Analysis: Existing operations
The user needs summary identifies the system design requirements in business terms. Requirements show the types of user workflows (ArcGIS technology patterns) needed to support the identified business operations, the peak number of concurrent users that will be working with this technology, where these users are located, and how they are connected to the central data center. It is also helpful to identify these users by department to aid in the review and requirements authorization process.

Figure A1-11.2 shows a user needs summary for the City of Rome existing operations. The spreadsheet identifies the City of Rome departments that will participate in the ArcGIS deployment. General ArcGIS technology patterns are identified for each deployment phase. Design requirements are established by identifying the number of concurrent users that will be using each identified ArcGIS technology pattern during the peak loads on the system. The spreadsheet shows where the users will be located and how they will be connected (over the network) to the central data center.



Once City of Rome completes and approves their user needs requirements summary, the CPT Calculator can be used to translate each of the ArcGIS technology patterns into user workflows that represent the identified business needs. Meetings with users of each ArcGIS workflow pattern can be used to inform the system design architect on the complexity and application requirements for each of the user workflows. The CPT Calculator software technology performance factors section can be used to generate appropriate performance targets for each of the ArcGIS technology workflow patterns.

Figure A1-11.3 shows the CPT Calculator being used to generate performance targets for the City of Rome existing operations. Software technology performance factors are selected for a medium complexity ArcGIS Desktop ArcMap 2D workflow which will represent performance targets for the local viewer clients.

Each organization's solution will be different.
 * Several decisions must be made during the design process before a final representation is collected in the capacity planning tool.
 * The process and discussion leading up to the final design should be documented as a record of decisions made during the design process.
 * Design documentation should clearly define the basis for the final workflow representation.



CPT Design requirements analysis: Existing operations
Figure A1-11.5 shows the results of our City of Rome CPT Design requirements analysis. The City of Rome user needs summary: Existing operations is used as a reference to configure the Design requirements. User workflows and site locations are configured to represent existing operations.

Peak concurrent users or throughput rates are entered for each user workflow in columns C and D. 

CPT Design network suitability analysis: Existing operations
Figure A1-11.6 shows the results of the City of Rome existing operations network suitability analysis.

Data center and remote site bandwidths were identified by the network administration and provided in the City of Rome technical architecture: Existing operations diagram. While configuring the requirements analysis and selecting the network bandwidth, the CPT Design tab completes the network suitability analysis. Network utilization (column I) shows less than 50 percent capacity for all locations, and display performance (column V) looks good for workflows at all site locations.

Estimated network cost is generated from the network pricing model and shown below the network selections (column H). City of Rome network service charges for their existing operations is $7,836/month.



CPT Design platform configuration: Existing operations
Figure A1-11.7 shows how the CPT Design tab was configured for the generic 4-tier platform architecture.

The City of Rome platform architecture diagram is used to identify the minimum number of server machines for each platform tier. A minimum of two virtual machines will be deployed for each server to support high-availability requirements.

Generic 4-tier platform architecture selection
 * WTS platform tier. ArcGIS Desktop ArcMap virtual sessions deployed on the Citrix virtual host platform tier (column I selection).
 * Web platform tier. Four (4) Internal and Public web servers deployed on the Server virtual host platform tier (column I selection).
 * GIS platform tier. Four (4) Internal and public GIS Server sites deployed on the Server virtual host platform tier (column I selection).
 * DBMS platform tier. Four (4) Production and Publication geodatabase servers deployed on the Server virtual host platform tier (column I selection).

"Best practice: The generic 4-tier generic platform configuration can be used to generate a proper virtual host platform recommendation."

"Warning: Accurate number of machines (fixed nodes) on each virtual tier is needed to generate proper virtual host platform memory recommendations.'"



CPT Design software configuration: Existing operations
Figure A1-11.8 shows the CPT Design generic 4-tier software configuration for the City of Rome existing operations.

For the generic platform tier configuration, the software assignment for each software component can be assigned from the top default configuration (LAN row, columns J through Q). All workflow software components are selected as default, assigned from the LAN default selection.

The generic 4-tier software assignment will assign workflow processing loads to the proper virtual server tier, and those loads will be sent to the selected virtual host platform tier. Platform sizing analysis will select the proper virtual host platform processor solution, while the proper number of machines on each virtual tier is needed to generate the final memory recommendations.

"Best practice: The generic 4-tier generic platform configuration simplifies software configuration."



CPT Design platform solution: Existing operations
Figure A1-11.9 shows the recommended platform solution for City of Rome existing operations.

Once the CPT Design tab is configured properly, and workflow software components assigned to the appropriate platform tier, excel completes the system architecture design analysis for the configured business state.

Resulting platform solution informs the Figure 11.11 City of Rome existing high-availability virtual server platform solution.

Citrix virtual host tier (52 concurrent ArcMap client sessions)
 * Three (3) Xeon X5687 8 core (2 chip) 3600 MHz platforms

Phase 1: ArcGIS Enterprise IOC


CPT Workflow Loads Analysis: ArcGIS Enterprise IOC
Figure A1-11.10 shows a user needs summary for the City of Rome ArcGIS Enterprise IOC. The ArcGIS Enterprise deployment will enable GIS Desktop users to leverage ArcGIS Pro applications on their local workstations, and be able to publish feature services to Portal for ArcGIS.

The user needs assessment peak load estimates assume all ArcGIS Desktop viewers are using ArcGIS Pro, and all ArcGIS Desktop editors will be using ArcMap. All ArcGIS Desktop clients are licensed for both products, so a mix of editors and viewers using ArcGIS Pro is acceptable. Most of the system of record editing workflows are supported by legacy ArcMap applications, and will not be able to leverage ArcGIS Pro for the initial deployment.

The new (PortFsvc) workflow represents new ArcGIS Pro published services deployed through Portal for ArcGIS following the ArcGIS Enterprise deployment. City estimates roughly 10 percent increase in the available internal Web services, represented by the PortFSvc workflows.



Figure A1-11.11 shows the CPT Calculator being used to generate performance targets for the City of Rome ArcGIS Enterprise IOC. Software technology performance factors are selected for a medium complexity ArcGIS Pro 2D workflow which will represent performance targets for the local viewer clients.

CPT Design requirements analysis: ArcGIS Enterprise IOC
Figure A1-11.13 shows the results of our City of Rome CPT Design requirements analysis. The ArcGIS Enterprise IOC user needs is used to update the CPT Design workflows.

CPT Design workflow changes
 * DeskMapMed workflows are replace by DeskProMed workflows.
 * New PortalFsvc workflow added to each internal site (peak load 10 percent of the WebIntHvy services).

Once the new workflows and peak concurrent loads are updates, excel updates the network suitability analysis. The RED cells indicate network contention, and the network bandwidth must be upgraded to support the additional traffic. 

CPT Design network suitability analysis: ArcGIS Enterprise IOC
Figure A1-11.14 shows the results of the City of Rome ArcGIS Enterprise IOC network suitability analysis.

Network bandwidth recommendations for low bandwidth connections (i.e. less than T3 = 45 Mbps) are typically twice the peak traffic (network utilization less than 60 percent). Higher bandwidth connections perform better at higher utilization rates. Selected bandwidth upgrade is a trade-off between performance and service provider cost.

ArcGIS Pro cannot be deployed on the existing Citrix host platform configuration, and remote users must access geodatabase servers across the WAN. The WAN traffic during peak loads is causing the identified network contention.

Recommended network bandwidth upgrades Data Center WAN = 310 Mbps Operations = 24 Mbps Freeberg = 155 Mbps Willsberg = 135 Mbps

Estimated network cost is generated from the network pricing model and shown below the network selections (column H). City of Rome network service charges to support the ArcGIS Enterprise IOC deployment is $12,289/month (Existing operations cost is $7,836/month.

Impact on display performance with the new ArcGIS Pro deployment is shown on the Workflow performance summary: ArcGIS Enterprise IOC.

This ArcGIS Enterprise deployment option would introduce a significant performance and operational cost impact. We will examine ArcGIS Enterprise deployment options for reducing this cost and improving display performance.

CPT Design platform solution: ArcGIS Pro Citrix remote clients deployment
Figure A1-11.32 shows the recommended platform solution for City of Rome ArcGIS Pro Citrix remote clients deployment.

The following steps should be followed to configure the ArcGIS Desktop VDI tier and the supporting Citrix virtual host platform. "Best practice: Xeon E5-2690v4 28 core (2 chip) 2600 MHz with NVIDIA Tesla GRID video card is the recommended VDI Host platform for 25 concurrent ArcGIS Pro clients."
 * Select VDI (virtual desktop infrastructure) with 6 core/node for WTS tier virtualization architecture (column I).
 * Select new Xeon E5-2690v4 28 core (2 chip) 2600 MHz Citrix virtual host platform (Column B). WTS VDI platform tier must be same selection.
 * Set WTS tier fixed nodes to 50 (column H). Total remote ArcGIS Desktop clients is 52, and clients will use a mix of ArcMap and ArcGIS Pro applications.  ArcGIS Pro loads are significantly heavier than ArcMap due to more efficient project workflow and concurrent batch processing jobs. City estimates peak load would be represented by 50 concurrent ArcGIS Pro users.
 * With WTS fixed nodes > 0 and no batch jobs, column AF identifies required Citrix virtual host platforms (2 host platforms).
 * Set Citrix virtual host tier fixed nodes = 2. Cost of the NVIDIA Tesla video cards with 25 virtual desktops/node for the Citrix virtual host tier is shown in column AF just below the Citrix virtual host tier.
 * Estimated additional ArcGIS Pro concurrent batch jobs supported with the current configuration is identified in the Citrix virtual host tier in column AF (top cell).
