Laptops with Linux: Definitely cheaper and it might be better
Laptops with Linux: Definitely cheaper and it might be better Alex Inman Director of Technology Whitfield School St. Louis, MO alex.inman@whitfieldschool.org Overview Motivation Design Rationale Results Project Motivation ● Whitfield Technology Plan Mission Statement – We believe that Whitfield School is a world-class institution which trains students to be leaders in a rapidly changing, global community. Thus it is our mission to provide members of our community with the appropriate tools and experiences to create leaders in such an environment. Leadership Global community Rapid change Common tools Why 1:1 Computing? ● Rapid Change – – ● Globalization – ● Commodification of information Need for synthesis and knowledge creation Need to access larger team and audience Leadership – Need for true technological literacy Project Motivation ● Manage Costs 14.00% 14.00% TCO Factors Gartner Group 17.00% 55.00% Capital End users operation Technical support Administration Project Justification ● Reduce Digital Divide – – – Goal #4: Seek opportunities to use technology to access diverse resources and communities as a means to participate in a wider community of learners Create replicable model for other schools Be a mentor or host (ASP) for other schools in transition Project Design Rationale ● Reliability – ● Stable Linux – ● Tough ThinkPad (“ruggedized” for students) Reduce malware risks and downtime Secure Citrix – Tighter, accessible anywhere and FAST! Higher reliability = Lower TCO Rationale ● Manage the TCO – – – – – Tough ThinkPads = fewer spares Linux OS reduces cost of machine (purchased w/o Windows OS) Linux/Citrix combo requires less beefy machine extending life to 4 years (from 3) Citrix reduces software costs (concurrent use model) Lower unit cost = lower insurance Rationale ● Widen Community of Learners – – – Tool provides greater access to people and resources 1:1 computer allows students to develop literacy while following personal interests Reducing TCO will hopefully lead to increased diversity in 1:1 schools Results ● Reliability – – – Per 100 laptops, we re-imaged 13 laptops/year versus 40/year at peer schools (hardware and software failure) Per 100 laptops, we had 5 insurance claims/year versus 28/year at peer schools with different hardware Citrix has remained available 99.996% of the time Results ● Manage TCO – – Acquisition cost down Day to day maintenance down ● ● – Fewer re-image sessions Almost no trouble shooting due to spyware Software cost down ● ● We employ more open source Concurrent licenses for Windows apps through Citrix (except Microsoft) Results ● TCO Breakdown (to date) Cost Windows Model Linux/Citrix Model Laptops Insurance Software Servers Image labor Difference Annual Savings with full roll-out Compared to peer schools $84,648.00 $15,540.00 $20,824.00 N/A $1,500.00 $56,628.00 $7,380.00 $19,560.00 $9,000.00 $487.50 $122,512.00 $92,568.00 $29,944.00 $119,776.00 Results ● TCO Breakdown (with potential improvements) Cost Windows Model Linux/Citrix Model Laptops Insurance Software Servers Image labor Difference Annual Savings with full roll-out $84,648.00 $15,540.00 $20,824.00 N/A $1,500.00 $56,628.00 $7,380.00 $19,560.00 $9,000.00 $487.50 $122,512.00 $92,568.00 $29,944.00 $119,776.00 Areas of Likely Improvement Results ● TCO Breakdown (with estimate improvements) Cost Laptops Insurance Software Servers Image labor Annual Savings with full roll-out Windows Model Linux/Citrix Model $338,592.00 $62,160.00 $133,080.00 N/A $3,000.00 $226,512.00 $29,520.00 $58,725.00 $22,500.00 $1,200.00 $536,832.00 $337,257.00 $199,575.00 Areas of Likely Improvement Results ● Internal Satisfaction – – – – 95% of faculty believe program is consistent with mission 96% of faculty and 92% of students believe 1:1 computing brings their learning to a higher level Students report spending 52% of their time in the Linux environment and 48% of their time using Windows programs through Citrix 93% of students report they are at least somewhat comfortable with the Linux terminal command line! Results ● Widen Community of Learners – – – – – 79% of faculty and 83% of students believe the program allows us to bring in more outside resources 74% of faculty and 85% of students believe the program allows us to interact more with people outside the immediate Whitfield community Sharing with others such as State of Indiana, Okoboji School District, and Episcopal, VA Sharing and learning from you!
