Solutions & PossibilitiesSolutions & Possibilities

Thin clientsGood in practice, but we have no spare server room space and eventually p , p p ywould need more network staff (another option we could not choose)

Server rooms are VERY costly, need lots of electricity, and A/COften the cost for thin clients hardware was not significantly less than a l t d ktlow cost desktop

LaptopsTypically a higher acquisition costs when equipped with similar

t d ktcomponents as a desktopHigh total cost of ownership (TCO)

Repairs take longerParts more proprietaryParts more proprietaryMore theft prone

Deployment detailsDeployment details

What Judson ISD did and where we did itDecided to focus X Series deployments in three areas:

Elementary school classroomsMiddle school classrooms

Each classroom end up with 4 student workstations

Library student stationsHow many have we deployed in year 1?

418 sets – which created an additional 1,254 computer seats

h d l d iHow many have we deployed in year 2? 343 sets – which created an additional 1,029 computer seats

What are the What are the benefits benefits of of X Series X Series solution?solution?Lower Acquisition CostsEnergy cost savings ( Green computing )Less electrical capacity needed in facilitiesLess A/C NeededLess e-waste created75% less network ports/drops needed

Less ports and drops can equate to at least $1200 savings per X Series set.

Less Electrical Capacity NeededLess Electrical Capacity Needed

Many schools lack electrical infrastructure to support large numbers of computersnumbers of computersOften impractical or cost prohibitive to bring in increased electrical serviceelectrical serviceOne 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 ya 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of computer seats in classrooms, while reducing electrical needs by 50%This means a 4 computer classroom can replace outdated

h dsystems with modern ones:And cut acquisition costs 50%Cut energy usage 73%Cut energy usage 73%

Less A/C NeededLess A/C Needed

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

Less eLess e--waste Createdwaste Created

Long term, there is much less e-waste for disposal, i.e. there are 3 less CPU’sLess to dispose of means:

Less pollutionLower disposal costs

Less Network Ports NeededLess Network Ports NeededLess 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 portCopper prices have been rapidly rising (a key component of network cables)network cables)Labor to install cabling is expensive (from $75 to $200 per drop)

Switches are not always very “green” – and canSwitches are not always very green and can consume a lot of electricity, as well as generate a lot of heat, so reducing numbers of switch ports canof heat, so reducing numbers of switch ports can help schools become greener

X Series Learning in Action

OtherOther

Technical IssuesWe learned we needed an audio solution per seatPut in inexpensive amplified speakers and headphonesThere is not enough output on multi box audio portStudents should be logged in under different user ggaccounts when using web applicationsTest all software you want to use prior to deployment to avoid unexpected surprises

Licensing IssuesCheck with operating system vendor and software vendors for their requirementsUsing Linux can save substantial licensing costs

Summary

Funding adequate technology is difficult in good years, but finding lower cost computing solutions is even more i t timportant now.Deploying X Series sets can cut your deployment costs for computing seats by 50% or morecomputing seats by 50% or moreX Series are not as green as trees, but they are much more efficient in energy usage e-waste and air conditioning thanefficient in energy usage, e-waste, and air conditioning than traditional computers.By replacing older PC’s with X Series you can cut energyBy replacing older PC s with X Series, you can cut energy usage by 70% or more.You or someone in your organization will increasingly need ou o o o you o ga a o a g y dto 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.
