3. Judson ISD pain points with providing increased
computer access to students
Cost
Laptops and desktops have high per seat acquisition cost
ap ops a d d s ops a g p s a a qu s o os
Maintenance
Computers have many common parts that fail or need
maintenance
Increasing computer technician staff not an option
Extended warranties can be very costly
Network Access
Many classrooms have limited network drops
Cabling and new switches are very expensive
Electrical Capacity
Many older schools have trouble supporting more than a
p p p
couple of computers per classroom
Often no easy way to increase electrical capacity
A/C is very expensive for schools and adding more full
co pute s substantially a ses /C demand
computers substa t a y raises A/C de a d

4. Solutions & Possibilities
Thin clients
Good in practice, but we have no spare server room space and eventually
p , p p y
would need more network staff (another option we could not choose)
Server rooms are VERY costly, need lots of electricity, and A/C
Often the cost for thin clients hardware was not significantly less than a
low cost desktop
l t d kt
Laptops
Typically a higher acquisition costs when equipped with similar
components as a d kt
t desktop
High total cost of ownership (TCO)
Repairs take longer
Parts more proprietary
More theft prone
Load Linux variant on old computers
Cheap/free solution – no OS cost
We have no Linux management tools and none offer functionality we
require at no cost
Still require expensive network ports and high electricity (higher than
modern CPU)
Increase number of service calls and need for repair technicians

5. What Judson ISD selected: The nComputing
X Series
What it is?
Modified thin client
It virtualizes the host OS and
shares the host’s resources
How does it work?
Install a PCI card in host machine
Connect up to 3 terminals (multi
boxes) per PCI card via cat 5 cable
Connect monitor, keyboard, and
monitor keyboard
mouse to each multi box

6. Deployment details
What Judson ISD did and where we did it
Decided to focus X Series deployments in three areas:
Elementary school classrooms
Middle school classrooms
Each classroom end up with 4 student
workstations
Library student stations
How many have we deployed in year 1?
418 sets – which created an additional 1,254 computer seats
How many h
have we d l
deployed i year 2?
d in
343 sets – which created an additional 1,029 computer seats

7. What are the benefits of X Series solution?
Lower Acquisition Costs
Energy cost savings ( Green computing )
Less electrical capacity needed in facilities
Less A/C Needed
Less e-waste created
75% less network ports/drops needed
Less ports and drops can equate to at least $1200 savings per X
Series set.

12. Less Electrical Capacity Needed
Many schools lack electrical infrastructure to support large
numbers of computers
Often impractical or cost prohibitive to bring in increased
electrical service
One X Series set with 1 green dual core and 3 terminals use
about the same electricity as a single Pentium 3 system with
y g y
a CRT monitor.
This allows a schools to double number of computer seats in
classrooms, while reducing electrical needs by 50%
This means a 4 computer classroom can replace outdated
systems with modern ones:
h d
And cut acquisition costs 50%
Cut energy usage 73%

13. Less A/C Needed
Less power consumption equates to less heat generated
per computing seat
Heat output is cut the same percentage as energy usage
This means heat output compared to traditional PC’s can
reduce heat output by 73% or higher.
p y g
This translates into large savings on A/C bills or on
retrofit of A/C systems to service hot rooms
Less $$ is spent on building A/C per computing seat

14. Less e-waste Created
e-
Long term, there is much less e-waste for disposal, i.e.
there are 3 less CPU’s
Less to dispose of means:
Less pollution
Lower disposal costs

15. Less Network Ports Needed
Less ports and drops can equate to at least $1200
savings per X Series set, if drops needed for
increased computer access.
How is this money saved?
Network switches can be very costly at more than $150 per port
Copper prices have been rapidly rising (a key component of
network cables)
Labor to install cabling is expensive (from $75 to $200 per drop)
Switches are not always very “green” – and can
green
consume a lot of electricity, as well as generate a lot
of heat, so reducing numbers of switch ports can
help schools become greener

18. X Series Learning in Action

19. Other
Technical Issues
We learned we needed an audio solution per seat
Put in inexpensive amplified speakers and headphones
There is not enough output on multi box audio port
Students should be logged in under different user
gg
accounts when using web applications
Test all software you want to use prior to deployment to
avoid unexpected surprises
Licensing Issues
Check with operating system vendor and software
vendors for their requirements
Using Linux can save substantial licensing costs

20. Summary
Funding adequate technology is difficult in good years, but
finding lower cost computing solutions is even more
important now.
i t t
Deploying X Series sets can cut your deployment costs for
computing seats by 50% or more
X Series are not as green as trees, but they are much more
efficient in energy usage e-waste and air conditioning than
usage, e-waste,
traditional computers.
By replacing older PC s with X Series, you can cut energy
PC’s Series
usage by 70% or more.
You or someone in your organization will increasingly need
ou o o o you o ga a o a gy d
to demonstrate how you are savings $$ and being greener in
IT. X Series fit into this strategy.
Make sure X Series fit your needs and test, test, test prior to
deployment.
