Background
2003: Day of Reckoning
– NT end of life announced
– Processing/memory requirements exceeding
hardware capabilities
– Rapid increases in IT problem ticket volumes
• Failing hardware
• System response time issues

The Challenge:
• PC Operating System (OS) at end of life
• Applications that are no longer supported
on old OS
• 2400 PCs that won’t support new OS
• Organization wants it all upgraded in 18 months
– Pent-up demand for new desktop systems
– Low tolerance for long upgrade cycle
– Funding considerations and timing

Usability Lab Overview
• 3 Configurations Presented
– Dell GX270 PC (current replacement standard)
– HP Blade PC
– Server-based computing platform
• Usability Lab Process
– 60 participants from across Mayo Clinic Arizona
– Participants tried each device for 15 minutes
– Able to access MS Office, IDX, Apollo, Intranet
– Completed short survey on experience with each
configuration

Where Did This Lead Us?
• All 3 technologies tested are viable in our
computing environment
– Perceptions of platforms differ, but all appear to have a
place in the organization (not “one size fits all”)
– Many differences related to setup issues that can be
addressed at implementation
• Other replacement device considerations
– Costs (acquisition, implementation, TCO)
– Timeline required to implement each platform
– Maturity of candidate technologies and vendors
– Internal capability to support each candidate technology

What is Virtual Mayo?
• Components of desktop upgrade
– Migration from Windows NT to Windows XP
– Replacement of sub-Pentium PC hardware
– Standardization on MS Office 2003
– Incorporates migration from eDirectory to Active
Directory
• Migration to Thin PC computing
• Creation of a virtualized desktop
Your applications,
your settings,
on any PC or thin client,
delivered on demand

“The Road Less Traveled”
“Citrix just won’t work
with our apps!”
Location-specific
Application settings
Poorly written apps:
“I own the whole box”
Virtual Desktop
16-bit apps

Apps written for
“Fat client”

“Perceptions…”
We tried Citrix
4 years ago –
and it failed!
You know,
MS Office
won’t run on
Citrix…
Multiple users
will make the
servers run
very, very
slow
IT won’t
be able
to
support it
Sounds
risky…PCs
are “proven”
I won’t be able to
map my own drives
or printers!

Building the Clinical Desktop
“Guiding Principles”
– Consistent user experience between XP and
Virtual Mayo environments
– Lock down settings where warranted
– Initial focus on a working desktop – keep end goal
of virtualization in mind
– Anything we roll out has to work well – rather have
it “right” than “fast”
17

Architecture
• Redundancy, redundancy, redundancy
– Split server farm across two subnets
– Redundant NICs
– Network load balancing solutions
• Seconds count
– Web front end
– High end thin client units
– Importance of “smooth roaming”

Internal Marketing Messages
• Thin clients rebranded as “ThinPC”
– Familiarity with PC terminology
– De-emphasize differences
• Virtual environment benefits emphasized
– Improved support model, reduced end-user downtime
– Future plans for application delivery
– Appeal to management – less variation among devices
and desktops
• Within IT – Focus on new technologies and
expansion of staff skills
19

Implementation
• Pilot rollout in clinical and hospital locations
– Lots of positive feedback
– Limited negative feedback (mostly application
issues)
– Opportunity to identify and address additional
issues – no substitute for “real world” experience
20

Implementation
• Strategy
– Swap PC for Thin Client in shared use areas
– Pre-configuring images
– Final server image rollout via Altiris
– Goal of all Thin Clients deployed by December 2005
21

Future Plans
• Citrix Presentation Server 4
– Application Isolation
– IP Address Virtualization
– CPU & Memory Optimization
– Printing
• Focus on virtualizing all applications before
considering fat client installation
• Shared virtual desktops with other Mayo
Foundation sites
