What is VDI?
“Any technology that
delivers a user desktop but
breaks the direct
relationship between the
user and at least one
primary component of the
Operating System
hardware”
How to Fail at VDI
Why A Virtual Desktop
• Mobility & Ubiquitous Delivery • Device Agnostic • Multiple Points of Entry Accommodate Varied Work
Styles
• Security • Containment within Enterprise
• Non-Persistency
• Auto-Healing / Refreshed Daily
How to Fail at VDI Business Decisions • Not knowing the business problem you’re solving with a Virtual Desktop • Believing desktop and server virtualization are the same • Doing too much
Operational Decisions • Overlooking the user environment • Holding on to bad habits • Collaboration and buy-in
Technology Decisions • Understanding requirements
• Understanding PoC ≠ Production
• Understanding End User Computing
How to Fail at VDI Business Decisions • Not understanding the business problem you’re solving • Believing desktop and server virtualization are the same • Doing too much
How to Fail at VDI Operational Decisions • Forgetting the user environment
• Hanging on to bad habits
• Collaboration
How to Fail at VDI Technology Decisions • Understanding requirements
• Understanding PoC ≠ Production
• Understanding End User Computing
Desktop = Layered Approach
• Operating System
• Applications
• User Profile and Setting
Legal Desktop = Layer Cake
• Initial capital investment • Infrastructure
• Servers • Storage • Networking • WAN Optimization
• Licensing
• Requires proper design & planning • For best performance • For High Availability • For Disaster Recovery
VDI Considerations
End User Computing
• Personalization
• Fast Logins • Outlook Cached Mode
• Windows Indexing and Search
• Windows 7 Aero Interface
• Multimedia & Graphics
• Flash • WMP
• Printing
VDI Case Study L.A.Hoffman
• Create a Virtual Desktop & Desktop management function with advanced
functionalities and meet current performance capabilities
• The VDI Desktop should be available from any endpoint, with emphasis on mobile
computing
• The VDI Desktop should be a persistent image for ease of transition
• The VDI should incorporate persona management
• The VDI should perform as well as older desktop technology
• The VDI should have a TCO that meets or exceeds the prior generation desktop
environment
VDI Case Study
Goals & Objectives
• Creates a new security infrastructure
• Dual environments during rollout period
• Storage & deduplication performance (boot storms and patch installations)
• Bandwidth requirements & bringing network management experience closer to the
Desktop
• Driving down the cost of computing & storage needs
• Material upgrade of staff skills
• Convergence of Desktop & Infrastructure teams & skills
• Immaturity of DR and other services
• One Central VDI installation means centralizing other services (Mail, Home drives,
‘local’ shared drives, etc)
VDI Case Study
Challenges
• 1100 desktops rolled now, moving to 2400
• Storage and performance issues resolved by moving to Flash with
deduplication. Array size is 10U, under 25% of a cabinet.
• Achieving great density – 55 desktops per server (3gb RAM per)
• Retraining of Desktop support team to meet new needs
• Evaluating next gen infrastructure, i.e. converged compute/storage
which holds promise to crush compute and rack space even further
VDI Case Study
Status
VDI Case Study
Boot Storm Impact
• Focus on the financial benefits versus the costs – implementation costs are only now
becoming sensible
• Technical knowledge requirements are non trivial
• All new processes & procedures for desktop management need to be thought out –
actual experience can deviate from textbook/course discussions, i.e. Patching/New
software rollout should be phased.
• Strong planning discipline is key as there are many moving parts
• Think through the impact on Tier 1 and 2 skills & service delivery
• VDI is beginning to make sense – but only if you have scale to justify the costs &
talent to deliver
