  • Today’s Discussion Avoid client virtualization pitfalls Overcome user challenges Migration considerations Address performance and scalability considerations Success stories Next steps
  • Client Virtualization: Challenges and Solutions Roy Francis VDI Service Architect FusionStorm rfrancis@fusionstorm.com View slide
  • Client Virtualization: Top 10 Mistakes10: Not Calculating Network Impact – Virtual desktops require more bandwidth – Virtual apps may not 9: No Profile Strategy – When organizations do not properly plan the profile strategy they are asking for failure – Especially true for Client Virtualization 8: Lack of Application Virtualization Strategy – Primary factor that often dictates the need for additional desktop images are application sets 7: Improper Resource Allocation – Fine line between maximizing the number of users a single server can support and providing the user with a good virtual desktop computing experience 6: Not Optimizing Antivirus – Simply adding AV to the virtual desktop can cause severe performance issues View slide
  • Client Virtualization: Top 10 Mistakes5: Not Managing Boot Storms – A virtual desktop startup has the single largest impact to any virtual desktop implementation4: Ignoring Virtual Desktop Optimizations – However, when delivering an operating system into a virtual desktop, many organizations do not go far enough to optimize the desktop for the virtualized environment3: Not Enough Cache – Simply adding more RAM to the Server won’t solve the problem2: Default Settings Used on Management Server1: Improper Storage Design – Without a properly designed storage subsystem, a user’s virtual desktop will slow down to the point of becoming unusable because storage becomes a bottleneck
  • ROI Review Savings on IT budgets, as reported by 20% businesses that have implemented desktop virtualization and are tracking ROI. How did they get there?
  • Performance Monitoring~70% What does that mean? First, not all customers have performance monitoring in their environment – but those that do; ~70% of the savings in IT budgets was created and reported through proper performance monitoring and management. Most of the Top-10 mistakes made couldn’t have been reported without proper performance monitoring in place.

  • Recommended Process Approach a CV project like any other major project Conduct Manage & Assess Plan Design Pilot Implement POC Support•Understand Business •Define Architecture •Develop detailed •Validate the •Migrate users in •Roll-out to Target •Manage and Monitor & End-User •Define staffing and design and technology Target Pilot Group Users user experience Requirements education operational plans •Ensure •Conduct multiple through best of•Identify investment requirements •Develop support plan feature/functionality pilots to validate breed tools requirements •Define Support plan exists solution readiness •Support end users through proper help desk training and incident management & response Most customers skip these key steps and move directly to a pilot.
  • What to Expect from the Roadmap Design?
  • Understand Desktop Virtualization Solutions
  • Infrastructure Costs
  • Application Integration& User Workspace Design Security Policies on what users can do Single Desktop Image Design Is Application Streaming viable? What else in the user environment needs to be controlled, managed and automated?
  • Validated Networking Design Core Switching and Routing Advanced Networking Components o Application Load Balancing o Site Load Balancing o Branch Site WAN Optimization o Datacenter WAN Optimization
  • What We Hear in the Field “Client Virtualization is just like Server Virtualization” – Beyond the possibility of using a server virtualization platform, this is a whole different ballgame “You can use your existing desktop licenses for virtual desktop deployment” – If you have Software Assurance, VDA is a benefit – If you don’t have SA, VDA is $100/device/year (subscription based on licensing agreement) “VDI can be rolled out in a month” – Most organizations take 6-12 months to assess, plan, design and pilot their solution
  • What We Hear In The Field “Presentation Virtualization or Terminal Services is ‘old school’ technology” – We continue to see customers adopt Microsoft RDS and Citrix XenApp since it is mature and proven technology. – CDW has deployed 5,000 seats of XenApp 6 + NetScaler “There is no ROI in Client Virtualization technology” – This is actually somewhat true. Calculating an accurate ROI first requires starting with an accurate TCO; something which is fairly difficult to calculate. This should include: • Desktop refresh costs • Desktop OS costs (including SA) • Help Desk/Service Desk costs • Desktop/Application administrative and break/fix personnel costs – A Client Virtualization solution, just like Server Virtualization requires significant upfront investments, but due to the lack of major power/cooling benefits, the ROI takes longer to achieve, and is usually 3-6 years out.
  • VDI Performance Pain 50% of all desktop virtualization projects stall or fail for 2 reasons: 1) Unacceptable End User Performance 2) Cost Overruns “Traditional management tools and desktop assessments are failing to deliver VDI performance, user acceptance and scalability.”
  • Audience Poll What is your biggest client virtualization pain? – User experience / performance – Cost control / ROI – Deployment complexity – Lack of client virtualization management tools – Client virtualization expertise

  • VDI Performance Assurance   Monitor   Deep Visibility Monitor VDI Service, Right-Size  Users, into not Silos for Great Sessions Preemptive Not Just ROI Detection VMs & Alerting
  • Monitor the VDI Service, Not Silos Monitor VDI Service, not SilosUsers care about the “service” IT operations teams focus on infrastructure silos VDI is slow The DNS servers are responding well to queries. VDI is not working The User / IT Management Disconnect VDI freezes The CPU usage of often the VMware servers is ok. This disconnect is a threat to the success of transformational IT initiatives & the promise of agility, scalability, and cost savings!
  • Monitor the VDI Service, Not Silos Monitor VDI Service, not Silos Know when user access is slowing
  • Get 360o Visibility Monitor VDI Service, not Silos Know which tiers are working and which are not. Virtual Server Monitoring Solutions cannot give you 360 o visibility. They focus on the virtualization platform only.
  • Monitor Every Layer, Every Tier Monitor VDI Service, not Silos There is an alert indicating The issue looks fine. vCenter an VMs within the virtual desktop. does not show any alert. The hypervisor looks fine.
  • Monitor Every Layer, Every Tier Monitor VDI Service, not Silos Oops – there is 26% retransmission from the virtual desktop
  • Automatic Root-Cause Diagnosis Monitor VDI Service, not Silos Root-cause The effect of the problem Deep visibility into every layer, every tier, & service-based correlation enable rapid/accurate diagnosis of performance issues.

  • Preemptive Detection & Alerting Preemptive DetectionIt is important to have the right metrics & Alerting Broad Coverage Deep Insights - LUN queue length Storage Application Virtual - VM CPU Ready Physical Cloud - TCP Retransmissions DatabaseNetwork - Memory leaks - Profile sizes Look for domain expertise in VDI, collect the right metrics. Virtualization Otherwise, it will be a case of “Garbage in, Garbage out”!
  • Auto-Baseline Key Metrics Preemptive Detection• Auto-compute time-of-day baselines & Alerting• Alert administrators when metrics violate baselines Preemptive detection & alerting lets administrators see and fix problems before users notice
  • A Preemptive Alerting Example Real-World Scenario Preemptive Detection & AlertingThe domain server goes down, pulling down the VDI service. Why?Event history provides a clue … The domain 5 hours earlier, a pro- server has failed active alert about and rebooted. memory leak!
  • VDI Performance Assurance   Monitor   Deep Visibility Monitor VDI Service, Right-Size  Users, into not Silos for Great Sessions Preemptive Not Just ROI Detection VMs & Alerting
  • Monitor Users, Not Just VMs Monitor Users, not just VMs • Workload of the VM is user-dependent • When a user complains, need to know which physical server and VM they are on • Need to know who the top users are for capacity planning • User information required for billing, capacity planning Poor user experience impacts VDI success. So focus on monitoring users, not just VMs!
  • Monitor Users, Not Just VMs Monitor Users, not just VMs When a user calls, search for the user Know which ESX/Xen server he/she is logged on to
  • Monitor Users, Not Just VMs Monitor Users, not just VMs See all the other users logged on to the same ESX/Xen host. See performance issues at the user level so you can fix and right-size your VDI environment for user satisfaction.
