1 Hawai i Medical Service Association (HMSA): Delivering Faster-than-Physical Virtual Desktops Stuart Shirai, Manager Network and Telecom Information Systems, HMSA Mark Choi, Infrastructure Engineer, HMSA Seth Knox, Director of Marketing, Atlantis Computing

2 About Hawai i Medical Service Association (HMSA) Blue Cross & Blue Shield of Hawai i Healthcare Insurance Provider Founded in 1938 More the 600,000 Members Non-Profit - $2 billion in Revenue 1,700 Employees 2

3 VDI Business Drivers BYOD Employees want to use devices we don t want to support Avoiding Desktop Refresh Previous Desktop Refreshes were painful and costly Security HIPAA Covered Entity with DLP requirements Enabling OS Migration Simplify and accelerate our Windows 7 migration 3

4 BYOD & Millennial Workforce Retention Use to high speed instant gratification Don t like standard Win XP physical PCs Bring variety of their own devices We can t support all the devices without VDI Can I use my MacBook to access my desktop? Now the answer is YES 4

5 Avoiding the Desktop Refresh Managed Two Desktop Refreshes 2003 and month periodic projects Supply Chain Stressed supply chain to breaking point Limited warehouse space and island state shipping issues Cost $ Million to refresh 80% of PCs ($1,397 Per PC) IT contract man hours and lost productivity during refresh I vowed never to do another desktop refresh. 5

6 Desktop Virtualization as the Solution Enables BYOD Program Enables access from any device (ipad, Phone, Mac ) Eliminates Desktop Refreshes Repurpose PCs - Extends the life of existing physical PCs Security Lowers risk profile of data loss and improves HIPAA controls OS Migrations Lays groundwork for OS migrations (i.e. Win XP to Win 7) My goal was to render the physical endpoint irrelevant. 6

7 User Experience Requirements Users wouldn t accept reduction in user experience for VDI Equal or better than physical PC performance Mobility between devices Critical to achieve user acceptance and project success Our CFO is on VDI with his MacBook and loves it! 7

8 VDI Workload Not like a server workload The VDI Storage Problem IO Profile - 80% write, 20% read, random small blocks Traditional SAN/NAS Expensive with limited IOPS Couldn t achieve desired performance Scalability Shared storage doesn t scale well Buy large storage array that scales out in big units I saw others making the mistake of treating desktops like servers. 8

10 Why Traditional SAN/NAS Wasn t an Option User Experience - IOPS requirements Physical PC with spindle ~ 150 IOPS/desktop Typical VDI deployment with SAN/NAS IOPS per desktop Atlantis ILIO + Fusion-io up to 1,000 IOPS per desktop Physical PC with SSD ~ 2,000+ IOPS per desktop Total IOPS Target 1,000 IOPS Per Desktop NAS Cost Per IOPS - NAS $1,000 per disk for 85 IOPS (RAID DP) = $11.70/IOPS NAS Cost Per Desktop (150 IOPS) NAS = $1,755 per desktop (storage only) 10

11 Software Virtual Machine (VM) Atlantis ILIO Introduction No agents or changes to desktop images Available on VMware vsphere Supports VMware View, ThinApp, Persona, Linked-Clones Integrates with all existing VMware infrastructure 90% Storage Reduction Increases Density 6x more users per server with Fusion-io Supports stateless and persistent deployments Migrate seamlessly from persistent to stateless VDI deployments 11

12 Atlantis ILIO Impact on Server Density Density Before Atlantis ILIO 40GB Virtual Desktop Image 1200 GB 40GB = 30 desktops per fusion-io Density After Atlantis ILIO 90% reduction to 4GB Virtual Desktop Image 1200 GB 4GB = 300 Desktops per Fusion iodrive2 Dell R810 Max density is CPU bound at % or 400GB remaining for growth 40GB Atlantis ILIO Software 4GB VM VM Density Density Fusion iodrive2 1.2 TB 12

13 Persistent to Stateless Migration Phase 1 - Start with Persistent Virtual Desktops Easier to get started Uses existing desktop management processes Users can install applications Implement user virtualization with AppSense Phase 2 - Migrate to Stateless Over Time Implement Application Virtualization Phase 21 - Stateless Persistent USER DATA APP APP/OS (Persistent) OS 13

14 Phase 1 Persistent VDI with User Virtualization User Virtualization Atlantis ILIO Software vsphere 5 Fusion iodrive2 1.2 TB Phase 1 - Persistent USER DATA APP/OS (Persistent) Shared Storage (Tier 2) 14

15 Phase 2 App Virt with User Self-Service Portal Planning User Self-Service Portal Select and install corporate approved applications Evaluating VMware Horizon SCCM

16 High Availability (HA) of User Profile with AppSense User profiles saved on network share using AppSense software User profile on shared storage New persistent desktops available on standby host Host Failure User receives a new desktop with their profile on logon Standby Host Only loss is user-installed applications (acceptable) Simple High Availability at Low Cost.

17 User Experience Results Boot Time 7 seconds MS Office Application Launch Time < 1 second Video conferencing Still needs to improve not optimized for VDI yet 17

18 Cost Analysis with Fusion-io & Atlantis ILIO CAPEX Costs Include Dell R810 Server Fusion iodrive 1.2TB Card (1 per host) Atlantis ILIO Licenses Cost $1,200 Total CAPEX Cost Per Desktop (Dell Server, Fusion-io, Atlantis ILIO) $1,157 Atlantis ILIO Cost Savings Before Atlantis ILIO - $1,157 After Atlantis ILIO - $480 $1,000 $800 $600 $480 Cost Savings Per desktop - $677 $400 Total Cost Savings (59%) $677 x 1,700 desktops = $1,150,900 $200 Remember the Physical PC cost Desktop refresh was $1,397 per PC $0 Before Atlantis ILIO After Atlantis ILIO 18

19 Lessons Learned & Best Practices 1. Keep users happy with performance project success depends on it 2. Plan for BYOD even if you aren t implementing a formal program 3. Self-Service Apps enable users to deploy their own apps 4. Reduce the security risk reduce your risk profile with VDI 5. Beware of the storage mistake size storage for IOPS & use Atlantis ILIO to cut cost and improve user experience 19
