Judson ISD implemented several green computing initiatives to reduce their environmental impact and energy costs, including virtualizing servers, deploying desktop virtualization with nComputing X-Series devices, purchasing more energy efficient computers and monitors, automating computer shutdowns, and establishing equipment recycling programs. This allowed them to reduce acquisition costs by 50%, lower annual energy costs per computing seat from $29.78 to $7.44, and save over $155,000 per year through automated shutdowns alone.

San Antonio, Texas, 9/17/2009

2. About Judson ISD
• 4th largest public school district in Bexar County, Texas
(San Antonio area)
• About 21 000 students and 3 000 employees
21,000 3,000
• 30 IT staff members
• Over 6,800 desktops and laptops
• Additional 2,550 virtual desktops (includes library desktops, which are not included on slide 11)
• 59 physical servers, 39 virtual servers
• More info at http://www.judsonisd.org

3. Green Computing – the Misnomer
• Can computing really be “green”?
• Technology is not particularly green
by
b most measures
t
• While technology can offer enormous
productivity and efficiency gains….
• It can have a huge negative impact on
the environment:
• Materials use
• Energy consumption
• H t creation (and need for
Heat ti ( d df
cooling)
• Discarding of old devices
g

4. Making Technology Greener
• B t t h l
But, technology can be made much greener by
b d h b
managing its negative impacts on the environment
• Look at how it makes sense for your organization to
limit or improve:
• Materials consumption
• Energy use
• Heat creation (and need for cooling)
• Di
Discarding of old d i
di f ld devices

5. Reasons for IT to be Greener
• Economics – Save $$$
• Reduce electricity consumption
• IT now responsible for paying its
ibl f i it
utility bills
• Social responsibility
• Concern for environment
• Can be good for public relations
• Cooling already at capacity

6. Major Green Economic Driver
• Energy Costs
• Energy costs often not seen
by IT
• But are a major
organizational expense
• In San Antonio, CPS Energy
estimates 50% increase in
bills in just 10 years
• Bills projected to rise at an
even faster rate after 2020
• Many utilities now offer
rebates for conserving

7. Green Computing Initiative (GCI) at Judson ISD

8. Judson ISD Green(er) Computing Steps:
1. Running virtual servers with VMWare, which reduces: number of
physical servers, power consumption, cooling, and data center
space requirements.
2. Remote management of desktops, servers and network equipment
3. Consolidating and virtualizing storage on SAN
4. Upgrading to more energy efficient servers
pg g gy
5. Purchasing Energy Star rated and EPEAT certified computers
6. Utilizing energy efficient LCD monitors and phasing out CRT
monitors
7. Eliminating almost all ink jet printers and providing a much smaller
quantity of shared laser printers and networked copiers

9. Judson ISD Green(er) Computing Steps:
8. Automating shutdown of most district computers
9. Recycling toner cartridges
10. Establishing procedures for redistribution, reuse, and recycling of
gp , , y g
technology assets
11. Recycling of disposed technology assets with company which
certifies that is uses responsible environmental practices and tries
p p
to reuse as many parts as possible
12. Pushing large volumes of student data to Judson ISD parents via
web applications, decreasing paper usage

13. Intensive desktop virtualization using nComputing X-Series
devices, saving the district money on acquisition, energy, cooling,
and network wiring g

10. Desktop Virtualization at Judson ISD
• Chose non-traditional approach
Ch t diti l h
• Virtualized a host PC locally and increased PC access by 300%
• Why go the route we did?
• Needed to offer increased computer access, but cost was the key factor
• We chose the…
• lowest deployment cost option
• most staff supportable option
ff bl i
• most green option
• What we chose
• nComputing X300
C ti
• What it is?
• Modified thin client
• It virtualizes the host OS and shares the host’s resources
• What we deployed –
• Deployed 761 X Series sets for an additional 2283 computing seats.

11. How desktop virtualization benefitted JISD
• Lower Acquisition Costs for 3,044 Seats
Acquisition for a PC only deployment
q y p y $ 2,374,320
Possible additional network growth $ 776,220

12. How desktop virtualization was greener
• Th
There was much less physical hardware deployed
hl h i lh d d l d
• Resulting in:
• less natural resources, packaging, etc are used at the onset
• less materials that need recycling and end up in land fills at the end
of the life cycle
• Purchased greener host computers
g p
• EPEAT gold/Energy Star computers with LCDs
• Much more energy efficient than older computers
• X S i virtual machines use 1 watt electricity per seat
Series i t l hi tt l t i it t
• At least 70% less HVAC capacity was needed
• 75% less building electrical capacity was needed per
computing seat
• Network port needs trimmed by 75%
