Designing and Deploying a Citrix Based Enterprise GIS Bob Milton California State Office
FY 2009 Architecture Data Center in Sacramento 5 Citrix servers, 64 bit OS Upgrading to Xeon 5500 In June Dell/EMC Storage Area Network 15 Tb of GIS data SqlServer 2005 AD Kerberos Pass-through Authentication Access controlled through AD groups 40 concurrent users (Average) 300+ Users
Life Cycle Existing Bureau lifecycle Servers => 5 years Desktops => 3 years Citrix Server Objective Match or exceed Desktop performance Recommended Lifecycle with Citrix: Servers => 3 years Desktops => 5 years
Sizing Current version of ArcGis is 32 bit, and not well threaded Many GIS operations will fully saturate a core, which affects other pre-existing threads on that core Example: Editors performing 5 minute edit operations between saves Someone launches several exports to pdf Citrix Server
Sizing Typical Load 2 duo cores Typical Load + 5 new exports to pdf 2 duo cores Existing threads spread among the cores Pre-existing threads are impacted Citrix Server
Sizing ESRI Recommendations: …. it is recommended to use Intel Xeon 5470 3330 MHz 8 core (2 quad-core chips) with 48 GB RAM ……. and can provide capacity for up to 120 concurrent Citrix users ….. My Recommendation: Unless you segregate your users Dont Do it! Citrix Server
Sizing Either Design for overcapacity (Its cheap!) Or Segregate your users between Real time processing needs (editing) from near Batch processing needs (Display, Query, Analysis) Citrix Server

Distance Matters!

Citrix Design Terminal Service Profile Provide a consistent user Profile Deploy Enterprise Settings Stored in profile Exception: Test Servers X:\Documents and Settings\userid \\blm\dfs\ca\so\eGIS_Profiles\userid FileserverCitrix Farm X:\Documents and Settings\userid\ Application Data\ESRI\ArcCatalog Test
Standardizing Builds Objectives Keep all servers in a build identical Minimize the number of active builds Some uncooperative apps may have to be on a separate build Do Not Manually Change Production Servers
Standardizing Builds Microsoft Deployment Toolkit 2008 Operating system deployment Virus OS Patches Scheduled jobs Installs and configures the OS including installing Citrix.
Standardizing Builds Citrix Installation Management Automation Can quickly build new servers (including virtual) Same order and procedure every time Standardization All servers built from the process are guaranteed to be the same Systems build documentation Build steps are used to document the system configuration
Agent Deployment & Launched through Start Menu Or Desktop Icons (Seamless Application Window) Start > All Programs > Citrix > Arcgis Launching Apps: Browser Deployment http://ilmcasoctws.blm.doi.net/ Launching Apps:
Configuration Management and Testing All system changes are managed through CM Request for change (ex: ArcGis extension) Test (A virtual server is created for each test) Approve or Deny (duplicates, doesnt work, causes problems) Deploy Users access the test server through: Start > All Programs > Citrix > Test
Managing printers and plotters Use Native drivers for plotters, and primary GIS printers Manage Drivers The local print server, local client, and all Citrix servers should use the same driver Use old Citrix print naming convention. (The new naming convention includes the session id in the print name which is then stored in the.mxd.
Folder/File Design Statewide Folders \\blm\dfs\ca\gisimage Office Folders \\blm\dfs\ca\oo\gisimage User Folders \\blm\dfs\ca\oo\loc\MyCitrix Field Offices manage their Folders All folders are physically in Sacramento
Implementation Started in the fall of 2004 Complete migration of all GIS data and work to a Citrix base EGIS architecture Staggered Office by Office Implementation (16 Field Offices, 30+ Remote Offices) Target, 1 office cutover per week Migrated office as is. No data Cleanup
Field Office setup Citrix client, User folders, print drivers) Backup Field Office Data Restore to Data Center User Orientation, Citrix FAQ File Replication, Turn off shares, Redirect Dfs links and M:\ drive mapping Field Office Citrix Deployment 1WEEK1WEEK 1 Hour No Change to data pathing No broken.mxds
Design Considerations Open Architecture Publish command prompt, explorer, etc User acceptance window Staggered implementation
