Wrestling with Shadows:
The Tragedy and Triumph of Classroom Virtualization

John Nickel
Colby Deitz
What is Virtualization?
The process of running several operating systems on a single
piece of hardware
Numerous virtualized computers, servers, and applications
“live” in one location
What is Virtualization?

Traditional Architecture

Virtual Architecture
One Machine, Many
Parts
Make VM’s

VM vSphere 5.1

Connect to VM’s

VMware View Client

Gather VM’s

VMware Horizon
View Administrator
Spring 2013 Pilot
Distributed to 35 classrooms in 2 buildings


Were specifically chosen

Goals:


Make more effective use of limited resources



Streamline support of classroom spaces
Spring 2013 Setup
Counting down…
What did we know?

What did we expect to happen?

Successfully implemented in our
Technology Commons

Hard to anticipate the results – this
had never been done before

Would be most visible test of
virtualization at WCU

Knew that some would take to it,
some wouldn’t
What was the result?
Where did it fall short?
Video playback
Stuttering, choppy video
Effected all multimedia
What is “acceptable” is subjective

USB Redirection
Trouble using USB drive on VM
Mostly an education issue, as
opposed to a hardware/software
issue

Impaired professor’s ability to conduct class the way they were expecting to
Faculty Reaction
Ranged from quiet and apathetic to loud and opposed


Both individuals and departments

Overall attitude of discontent
Numbers don’t lie, but
they’re not everything
How did we react?
Utilized the “full” partition
Stopped work on projects to focus on tickets
Assembled a team from all areas of IT


Tested every part of our virtual environment
What did we learn?
Virtualization is not the be-all-end-all for everyone
Need to be aware of our clients and their different use-cases
There needs to be a tangible benefit to IT (if not, then why do it?)
Software/curriculum needs
Student’s don’t react the same as faculty
Students
Don’t provide much feedback
Accept something is the way and
adapt
More fluid – accepting of change
If they can do their work, they’re
happy

Faculty
Quick to say when something
isn’t working the way they
want/need it
Greater need for technology to
work a certain way


If not, then it can stop class
in it’s tracks



Can be harder to workaround things
A new day dawns…
Shining brighter with
vCat
Shedding light
Greater emphasis on educating our clients
Scheduled several drop-in sessions over 2 weeks for training
and questions
Sent email notifications to all faculty, deans, and department
heads
Illumination
Found our professors have a greater need for multimedia, and not the
programs found on vCAT


Not a failure, showed us something we never realized before



Can leverage virtualization where it should be used

Not mandating they give up traditional methods, presented as a tool
Onwards and Upwards
Spring 2013 wasn’t fun or flattering for us
Listened, made changes, and acted appropriately


Beginning of Spring, it seemed like everything exploded



Beginning of Fall, everything just worked

Starting to pursue application virtualization
Don’t win every fight, but with perseverance and planning you can win the
war
Thank you for your time!

Wrestling With Shadows

  • 1. Wrestling with Shadows: The Tragedy and Triumph of Classroom Virtualization John Nickel Colby Deitz
  • 2. What is Virtualization? The process of running several operating systems on a single piece of hardware Numerous virtualized computers, servers, and applications “live” in one location
  • 3. What is Virtualization? Traditional Architecture Virtual Architecture
  • 4. One Machine, Many Parts Make VM’s VM vSphere 5.1 Connect to VM’s VMware View Client Gather VM’s VMware Horizon View Administrator
  • 5. Spring 2013 Pilot Distributed to 35 classrooms in 2 buildings  Were specifically chosen Goals:  Make more effective use of limited resources  Streamline support of classroom spaces
  • 7. Counting down… What did we know? What did we expect to happen? Successfully implemented in our Technology Commons Hard to anticipate the results – this had never been done before Would be most visible test of virtualization at WCU Knew that some would take to it, some wouldn’t
  • 8. What was the result?
  • 9. Where did it fall short? Video playback Stuttering, choppy video Effected all multimedia What is “acceptable” is subjective USB Redirection Trouble using USB drive on VM Mostly an education issue, as opposed to a hardware/software issue Impaired professor’s ability to conduct class the way they were expecting to
  • 10. Faculty Reaction Ranged from quiet and apathetic to loud and opposed  Both individuals and departments Overall attitude of discontent
  • 11. Numbers don’t lie, but they’re not everything
  • 12. How did we react? Utilized the “full” partition Stopped work on projects to focus on tickets Assembled a team from all areas of IT  Tested every part of our virtual environment
  • 13. What did we learn? Virtualization is not the be-all-end-all for everyone Need to be aware of our clients and their different use-cases There needs to be a tangible benefit to IT (if not, then why do it?) Software/curriculum needs Student’s don’t react the same as faculty
  • 14. Students Don’t provide much feedback Accept something is the way and adapt More fluid – accepting of change If they can do their work, they’re happy Faculty Quick to say when something isn’t working the way they want/need it Greater need for technology to work a certain way  If not, then it can stop class in it’s tracks  Can be harder to workaround things
  • 15. A new day dawns…
  • 17. Shedding light Greater emphasis on educating our clients Scheduled several drop-in sessions over 2 weeks for training and questions Sent email notifications to all faculty, deans, and department heads
  • 18. Illumination Found our professors have a greater need for multimedia, and not the programs found on vCAT  Not a failure, showed us something we never realized before  Can leverage virtualization where it should be used Not mandating they give up traditional methods, presented as a tool
  • 19. Onwards and Upwards Spring 2013 wasn’t fun or flattering for us Listened, made changes, and acted appropriately  Beginning of Spring, it seemed like everything exploded  Beginning of Fall, everything just worked Starting to pursue application virtualization Don’t win every fight, but with perseverance and planning you can win the war
