growing concerns
Growing Concerns…
  • Long-term funding of technology hardware
  • Ability to keep up with our current replacement schedule for laptops and desktops
  • Providing learners the ability to access resources at any time regardless of the hardware they are using
  • BYOD
  • Increased energy costs
  • Growing cost of supporting the number of devices within our environment
vdi desktop virtualization whatever you call it is happening
VDI, Desktop Virtualization – Whatever You Call It – Is Happening

Whatever shape it takes, whatever technology solutions win out, however IT manages to deploy it, desktops will become far more highly virtualized over the next several years. The shift to a more cloud-like computing environment is real, the growth of IT-based-services is real, the path to a new paradigm is real and being blazed.

rapid growth of mobile devices
Rapid growth of mobile devices

According to Gartner, 80 percent of businesses will support a workforce using tablets within the next year and by 2014, 90 percent of organizations will enable corporate applications on personal devices. The rapid mobilization of today’s workforce explodes the traditional concept of a single corporate PC where the PC actually resides on a desktop.

five computing trends through 2015
Five computing trends through 2015
  • The cloud promises to deliver a range of benefits, including a shift from capital-intensive to operational cost models, lower overall cost, greater agility and reduced complexity.
  • Hybrid Cloud Computing will be a necessity.
  • As cloud computing adoption proliferates, so does the need for consumption assistance. This would involve a service provider to play an intermediate role in cloud computing.
  • Cloud-Centric Design becomes a necessity.
  • Cloud Computing influences future data center and operational models

guiding question
Guiding Question…

How can we provide 24/7 access to technology resources for all staff and students regardless of the device that they are using?

vdi research
VDI Research
  • Have been researching potential long-term solutions since 2010
  • Tested VDI solutions like Citrix, VMWare and nComputing
  • Multiple Proof-of-Concepts performed across all levels
  • Detailed performance analysis and ROI comparison
  • Interviewed multiple vendors to find the right fit
  • Reached out to other K-12 districts for input/feedback
what is a potential long term solution
What is a potential long-term solution?
  • VDI – Virtual Desktop Infrastructure
  • Re-purpose existing desktops/laptops and extend their useful life as long as possible
  • Long-term migration to zero client devices as old desktops break
what is vdi
What is VDI?

Virtual desktop infrastructure (VDI) is the practice of hosting a desktop operating system within a virtual machine (VM) running on a centralized server. VDI is a variation on the client/server computing model, sometimes referred to as server-based computing.

what are the potential benefits of a vdi solution
What are the potential benefits of a VDI solution?
  • Repurpose aging Desktops/Laptops to work like “new” devices
  • Extend the hardware lifecycle of Desktops & Laptops
  • Save money and repurpose bond dollars
  • Meet growing demand for BYOD
  • Break/fix & user cost reduction
  • Improved application deployment time
  • Reduce energy costs over time
  • Prevent Trickle-Down Deployments or “Desktop Shuffle”
anyone else using vdi technology
Anyone else using VDI technology?
  • Common place in business world
  • Dallas County Schools (DCS)
  • Tyler ISD
  • Fort Worth ISD
  • Northwest ISD
  • Southlake Carroll ISD
  • Mansfield ISD
  • Aledo ISD
  • Longview ISD
  • Clear Creek ISD
  • Pearland ISD
  • Many others that are on the verge of implementing some sort of VDI solution
current environment
Current Environment
  • 3000 Desktops / 4000 Laptops
  • Cost of Desktop w/ monitor $1,100
  • Average Cost of Laptop $1,000
  • Electricity is .085 cents per Kilowatt
  • $24 Dollars per hour for PC Technician support of devices
replacement schedule desktops laptops vs vdi 4500 devices
Replacement Schedule (Desktops/Laptops) vs. VDI – 4500 Devices

Fine Print

**I don’t have a crystal ball and technology changes on a daily basis

**Who knows what we might be considering 3 to 5 years from now

**Potential long-term savings is based on today’s prices and can change at any time

specific products purchased

why did we choose a vblock solution
Why did we choose a vBlock Solution?
  • Time to production
  • Purposeful engineering for entire vBlock architecture
  • Single point of contact for any issues that arise (VCE)
  • Compatibility Support Matrix defined for all products
  • All product updates are fully tested and certified across all components…which leads to peace of mind!
deployment approach
Deployment Approach
  • Educating & Marketing – Why are we doing this?
  • PHASED approach to ensure success!
  • - Focus on older Dell 755/760 PCs, Latitude D530 Laptops, and netbooks
  • - Deploy in generic areas first to provide more time to test with peripherals before expanding out (general purpose labs, libraries, elementary classrooms, etc.)
  • Provide VMs for BYOD and At-Home Use for staff/students
where have we deployed vmware view
Where have we deployed VMware View?
  • Initial rollout for start of 2012-13 school year:
  • All elementary classrooms (~300)
  • All elementary labs (~225)
  • All libraries (~100)
  • Generic computer labs at CHS (~90)
  • Fall/Spring rollout:
  • Expand to older laptop mobile carts @ all campuses
