Our IT Team and Who We Serve
2-person IT team for virtualization
Broad set of use cases
– USF Students
– USF Professors
– Practicing Physicians in the Clinic
– Operating Rooms
– Procedure Rooms
![Page 4: unidesk_vdi_usf_health_presentation](https://reader033.vdocument.in/reader033/viewer/2022042819/55cc9b69bb61eb2d208b461a/html5/thumbnails/4.jpg)
Why VDI?
In Healthcare, desktops MUST perform well
– Clinicians want “instant-on,” “follow-me” high performance experience
Give clinicians and staff faster, more secure access to key healthcare apps
– Apps change constantly, desktops require frequent re-config
– Both harder to do on physical PCs
Reduce cost, IT effort needed to deliver desktops and keep Windows and
applications up to date
– See above
BYOD enabled by VDI lets us support clinician needs for mobility
Growing quickly – need to be able to scale desktops on-demand
Privacy, security, and compliance of getting data off the edge

Our Implementation Approach
Make IT the guinea pigs
– Large in-house development team, CIO, and rest of IT went to
virtual desktops first
– If it worked for us, it can work for clinicians
Try to satisfy most difficult non-IT use cases first
– Operating and Procedure rooms

2 Big Takeaways From Research & Initial Rollout
Storage performance doesn’t scale on spinning disk
– I/O performance and availability not acceptable
– Configuration and troubleshooting too difficult
Virtualizing ~100 apps and managing our different desktop
configs were too hard for our small IT team
– AllScripts EMR and GE Centricity plug-ins for PACS, radiology
– Visual C++, Visual Studio, .NET for in-house developers
– Firefox, Google Chrome, Office, SAS, Pharos, ArcGIS for staff
– Too many Windows images to patch

Management Solution: Unidesk
Provision non-persistent desktops and persistent desktops
– Operating and Procedure rooms have non-persistent desktops
– IT, Clinical, General Staff users have persistent desktops
One Gold Windows OS layer (shared VMDK) for easy patching
– No needed for multiple images for each cloned parent VM
Application layering – package once, apps act as if locally installed
– Apps stored as unique VMDKs, shared by many desktops
– AllScripts EHR, developer tools interoperate with all dependent apps
– Easy! Takes only a few minutes per app, same as installing on a regular PC
Rollback “Personalization” layer for instant break/fix
Installs quickly as vSphere appliances
Integrates with VMware Horizon View
– Adds layered VMs to View pools for access through View clients
Small storage footprint
– Pure Storage enhances Unidesk’s shared VMDK architecture so each
persistent and non-persistent desktop uses only 4 GB of storage
The Magic of “Layers”

Learnings and Future Plans
VDI with Pure Storage, Unidesk, and VMware Horizon
View is a success
Seeing a 10.3:1 storage reduction and great performance
with Pure Storage
Unidesk eliminates need for clone replicas and
re-composes, so we’re saving space, making end users
happier with persistent desktops, and scaling with 1 gold
image and simple app layering
Continuing our rollout, focusing on clinical users next
