CPT Design requirements analysis: Water Utility deployment
The City of Rome Design includes local and public internet clients, plus clients from eight (8) remote sites. The CPT requirements analysis will be configured to support all user locations.

Figure A1-11.37 Phase 2 Operations and Water Utilities user needs summary is used as a reference to configure the Design requirements. User workflows and site locations include the Phase 1 ArcGIS Enterprise IOC workflows and the additional Phase 2 Water Utility operations.

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

Figure A1-11.40 (section 1) shows results of the City of Rome CPT Design requirements analysis for the first 5 locations. 
 * City of Rome City Hall LAN
 * Operations
 * Freeberg
 * Willsberg
 * Perth

Figure A1-11.41 (section 2) shows the results of the City of Rome CPT Design requirements analysis. Following locations are included in this analysis:
 * Wawash
 * Jackson
 * Petersville
 * Rogerton
 * Public Internet clients

While the CPT Design requirements are configured, Excel compares peak site traffic with available bandwidth and completes a network suitability analysis (RED cells identify traffic bottlenecks). Network bandwidth must be updated to support Phase 2 business requirements. 

CPT Design network suitability analysis: Water Utility deployment
Data center and remote site bandwidths were identified by the network administration and provided in the City of Rome technical architecture: Water Utility deployment 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.

Figure A1-11.42 (section 1) shows the results of the network suitability analysis and recommended network bandwidth upgrades. Following locations and network connections are included in this analysis:
 * Data Center LAN = 1000 Mbps (29% peak utilization)
 * Data Center WAN = 310 Mbps (49% peak utilization)
 * Operations = 45 Mbps (47% peak utilization)
 * Freeberg = 45 Mbps (68% peak utilization)
 * Willsberg = 45 Mbps (63% peak utilization)
 * Perth = 12 Mbps (9% peak utilization)



Figure A1-11.43 (section 2) shows the results of the network suitability analysis and network bandwidth upgrades. Following locations and network connections are included in this analysis:
 * Additional Data Center WAN sites
 * Wawash = 24 Mbps (65% peak utilization)
 * Jackson = 18 Mbps (43% peak utilization)
 * Petersville = 45 Mbps (52% peak utilization)
 * Rogerton = 45 Mbps (52% peak utilization)


 * Data Center Internet clients = 2500 Mbps (47% peak utilization)

Estimated network cost is generated from the network pricing model and shown below the network selections (column H). City of Rome network service charges following the Phase 2 Water Utility deployment is $18,908/month. 

CPT Design generic 4-tier platform configuration: Water Utility deployment
Figure A1-11.44 shows how the CPT Design tab was configured for the Phase 2 generic 4-tier virtual server platform architecture. The GeoEvent server is configured on a dedicated physical tier to minimize deployment risk.

The City of Rome Figure 11.43 phase 2 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 virtual server to support high-availability requirements.

Generic 4-tier platform architecture selection
 * WTS platform tier. ArcGIS Desktop deployed on the Citrix virtual host platform tier, with VDI and 6 core/node for the virtual desktop configuration (column I).
 * GeoEvent platform tier. GeoEvent server role is configured on a dedicated physical server tier.
 * Web platform tier. Supports separate internal and external Web and Portal sites deployed on the Server virtual host platform tier (column I selection).
 * GIS platform tier. Supports separate internal and external ArcGIS Server publishing and hosting sites deployed on the Server virtual host platform tier (column I selection).
 * DBMS platform tier. Supports production and publication geodatabase servers, internal and public relational data stores, and public geospatial big data store all deployed on the Server virtual host platform tier (column I selection).

"Best practice: The generic 4-tier generic platform virtual server 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 generic 4-tier software configuration: Water Utility deployment
For the generic virtual server 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 virtual server workflow software components are selected as default, assigned from the LAN default selection.

The generic 4-tier software configuration will assign workflow processing loads to the proper virtual server tier, and those loads will be sent to the selected virtual host platform tier. CPT Design 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.

Figure A1-11.45 (section 1) shows the CPT Design generic 4-tier virtual server software configuration for the City of Rome Water Utility deployment. Following sites and workflows are included in this analysis:
 * Data Center LAN = 11 local workflows
 * Data Center WAN sites
 * Operations = 8 workflows
 * Freeberg = 4 workflows
 * Willsberg = 4 workflows
 * Perth = 4 workflows



Figure A1-11.46 (section 1) shows the CPT Design generic 4-tier virtual server software configuration for the City of Rome Water Utility deployment. GeoEvent Server role will be deployed on a separate dedicated physical server tier to minimize deployment risk. Following sites and workflows are included in this analysis:
 * Data Center WAN sites
 * Wawash = 4 workflows
 * Jackson = 4 workflows
 * Petersville = 4 workflows
 * Rogerton = 4 workflows
 * Data Center Public Internet clients = 6 web service workflows and GeoEvent ingestion workflow transactions.

GeoEvent workflow SOC load is assigned to the GeoEvent platform tier. The GeoSpatial data store is part of the virtual DBMS platform tier.

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

CPT Design generic 4-tier platform solution: Water Utility deployment
Figure A1-11.47 shows the recommended platform solution for City of Rome Water Utility 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 200 (column H). Total remote ArcGIS Desktop clients is 209, 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 200 concurrent ArcGIS Pro users.
 * With WTS fixed nodes > 0 and no batch jobs, column AF identifies required Citrix virtual host platforms (8 host platforms). CPT Design high availability configuration is N+1; City decides 8 host servers supporting 200 ArcGIS Pro clients (25 virtual desktops per node) is adequate to meet their high availability requirements.
 * Set Citrix virtual host tier fixed nodes = 8. 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 ($160,000).
 * 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 - 103 concurrent batch jobs).

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.
