Segment Distribution
In a Client Server configuration, if all you have to work with is two (2) tiers –a Client and a Server – then you will have to be creative as to how you distribute the six application segments between the two platforms.

Virtualization
New Emerging Technology– Servers– Applications – Desktops
Platform virtualization, which separates an operating system from the underlying platform resources – Full virtualization – Hardware-assisted virtualization – Partial virtualization – Paravirtualization– Operating system-level virtualization

Citrix Printing / Plotting Issues
Print streams can be very large for plotters 10-400 MB.
Low-bandwidth connections (T-1 or less) will be more problematic –but it still can work if printing bandwidth is managed properly.
Printing administration can be an issue with WTS/Citrix especially with large organizations.
PS4 dynamic printer names do not work with ArcGIS (because the printer name is stored in the mxd map document).
PS4 Universal Print Driver does not work well with most plotters.
Printer driver compatibility is very important.
Printing problems may impact the overall Citrix server performance.
Enterprise Server-based Printing Process
RDP / ICAProtocol
Citrix / Terminal Server
Citrix Printing Solutions
Avoid using client side printing – recommend using a print server in the data center. Offload print driver rendering from TS/Citrix server to a separate print server.
Try to use a print subsystem that uses compression.
Test all print drivers – a long driver mapping time reveals a driver specific problem. Tightly control drivers on Citrix application servers.
Citrix Presentation Server configuration is important to look at.
Use Universal Print Driver (UPD) for normal (non-plotter) printers or those where native print driver does not work.
Consider third-party solutions to help with printer administration. (i.e. direct print to plotters, i.e. ThinPrint or ZEH)
Look at printing bandwidth management. (Citrix Universal Printer Driver & Third-party solutions, i.e. ThinPrint or ZEH)

Top 10 Benefits of a GIS Citrix Farm1. Guarantee best performance – Good corporate LAN “citizen”
• Enables remote GIS users to access GIS desktop system across slower WAN connections
• Smaller footprint for GIS desktop users on faster Corporate LAN – (GIS fat-client comparable to Video Conference footprint on corporate network)
• Even possible to connect over 56K dial-up connections2. More stable across WAN connections (latency tolerant)
• Application can disconnect and then reconnect without losing Citrix session• Less affected by latency issues across WAN
3. Lower cost for hardware requirements and system administration• No need for costly high-end workstations for each GIS user
4. Easy to scale over time5. Centralized management / configuration of Client GIS software6. Easier detection and resolution of software bugs and performance issues7. Easier to distribute upgrades or bug fixes8. Faster turn-a-round for development & QA integration testing of custom GIS
extensions: • Development Test Production
9. Any authorized GIS user can access all three environments at the same time from their local workstation
10. Remote Monitoring/Control - Shadowing
Citrix XenApp vs. MS Windows Terminal Server Alone
A Citrix solution offers the following:Citrix enables published applications within a seamless window
XenApp 4.5/5.0:– Improved Performance for Raster Images (Progressive Display)– Application Isolation: i.e. ArcGIS 9.0 & 9.1 on same server– Better Virtual Memory Space Management– Prevent a Single Application from Consuming a CPU– Universal Print Driver Support– Enhanced Security Options
Other XenApp components:– Web Interface to Launch Published Apps– Advanced load management of Citrix servers (LM)
• TS Load-balancing is network-based and limited to 32 nodes• TS Load-balancing requires the Enterprise Edition to really be effective
– Automated software installation across servers (IM)– Server monitoring & statistic collection (SM)– ICA Client provides Secure Proxy Connection to the Citrix Servers– Advanced session shadowing– Centralized license management– Centralized printer management– ICA Client - Smallest network bandwidth (Win2000 only)

How Many Concurrent GIS Users Can a XenApp Server Support?32-bit vs. 64-bit Windows Server OS
32-bit Windows Server OS• 15-20 GIS users 2 core server w/ 4 GB RAM
• 30-40 GIS users 4 core server w/ 16 GB RAM(using Enterprise version of Windows Server OS & /PAE switch)
64-bit Windows Server OS (Requires 64-bit Drivers)
• 40-60+ GIS users 8 core server w/ 32 GB RAM• 80+ GIS users 16 core server w/ 64 GB RAM
Today’s Intel & AMD based servers are so fast and powerful that the primary hardware issue for Citrix servers
is the amount of Memory not CPU capacity or speed.

4 GB (2^32) address space– 2 GB kernel mode address space
