Transcript of Deconstructing the brian paradox
- 1. Deconstructing the Brian Paradox VDI is here ready or not The manic Logic of VDI Chetan Venkatesh CTO & Founder Brian Madden Guru Briforum 2010
2. What is Brians paradox
- VDI is poor on session density
- Inherent VDI limitations
-
- Large Storage footprint
-
- Large Datacenter footprint
-
- Expensive Infrastructure
- Given the limitations of VDI
-
- 90% of the world will use Client based Virtualization
-
- VDI will remain a niche use case
3. DESKTOP COMPUTING MODELS CIRCA 2009 Physical Desktop Physical Desktop on Virtual Storage TS baseddesktop & remote applications Virtual Desktop on VDI Virtual Desktop on Type 2 ClientVirtual Desktop on Type 1 Client 4.
- VDI 65%
- TS-5%
- Client based Virtualization-20%
- Physical Desktops 10%
- * In the typical Fortune 500 Enterprise
- @Based on informal poll of 10 F500 CIOs by Chetan
DESKTOP COMPUTING MODELS CIRCA 2015* @ 5. 3 themes to explore
- How personal computing has changed
- Moores law and its impact on the Datacenter
- Deployment models
6. Personal Computing is different now! cp/m Ms-dos netware Windows 95-2000-XP Linux KDE/Gnome Mac OSX iphone iPad Android 7. Users dont care aboutour version of Personalization* * At least not the way we think about it today 8. The web changes personalization FB Connect/OpenSocial Roaming Profile/Appsense/Res Entitlements Policies Security Application subscriptions profile 9. The web changes Apps Thats a cool App! Im going to subscribe to it 10. And makes the Desktop less important Rich Profile &Context of what I like & what I trustRigid set of policies On what I can doSocialCloud Enterprise Cloud 11. Vectors for 2015
- Rich Content & social applications will hasten the demise of relic PCsfrom being the primary computer
-
- Consumption oriented devices will be the users primary personal computer i.e. tablets, netbooksand smart phones
-
- Windows will become middleware simply a connection between users and enterprise apps. Windows is a place to run apps
> + 12. Vectors for 2015
- Users will develop a far more sophisticated definition of personality and force Enterprise to adopt it
- Social Graph gleaned from:
- Twitter for Enterprise/Salesforce
- Enterprise wikis
- Google Docs
13. Vectors for 2015
- Users will no longer care about Application installation & management
-
-
- iTunes, Android market & Citrix Dazzlewill be interfaces to application provisioning
-
14. An uncharitable comparison = PC PC +Client hypervisor (type 1|2) NOTHING HAS FUNDAMENTALLY CHANGED
- No CAPEX Proposition
- Marginal OPEX value
- Frankenstein PC
15. The PC era is dead.We need closure with it, its architecture and all attempts toFrankenstein it with Client Virtualization 16. Moores law & the datacenter 17. The 3 Forces shaping IT
- Users
-
- Users want a coherent and flexible Compute paradigm
- The web
-
- The web is the master repository of my personality
- Moores law
-
- Moores law has more amplitude in the datacenter
18. Dematerialization & liquidity
- Dematerialization is the transformation of physical objects into mental/thought/logical objects
- Dematerialization creates liquidity and opportunities for arbitrage
Dematerializationaka virtualization 19. A NEW ARCHITECTURE FOR DESKTOP COMPUTING
- The Rackis the new computer
-
- It is now the NEW fundamental element of compute
- 10GEthernet is the new BUS
-
- Connecting specialized pools of compute, storage & memory
- The Hypervisor is the kernel
-
- VMs are simply threads/processes to be scheduled across the rack (or racks)
- The software mainframe is thenew OS
-
- Memory Page Sharing, Primary Storage Deduplication, CDP, data mirroring, DR are new primary subsystems of the new Datacenter OS. Manyof these are astronomical in cost/complexity to do on the PC.
20. Key points to think about
-
- Where should we run the desktop VM?
-
-
- As a type 2 VM on a windows PC?(ala moka5, Vmware Fusion & w/station)
-
-
-
- As a type 1 VM on a bare metal PC(ala Citrix XenClient?)
-
-
-
- In the datacenter as Hosted Virtual desktops?(VDI)
-
? Datacenter = compute liquidity
- Shared resources = better flexibility
- Dial up/down resources
- Live migrate VMs, users, capacity
- Arbitrage comes from the ability to move between clouds
21. 2 Key Questions
- If there was parity in performance & experience between a VDI and a client hosted desktop, what would IT want to give him/her?
- if VMs are pure execution containers, and all the content (OS/Apps/user data) are centralized (oraccessible from everywhere) - where would Enterprise IT run the VM and why?
Datacenter
- Fine grained control
- Tighter Security
- Dynamic Capacity
- Disaster recovery and & Business Continuity
22. Common VDI myths
- Expensive Servers
- Expensive Storage
- Expensive Datacenter
-
- Power/cooling/real estate
23. Expensive Servers Desktop PC
- Cheap to acquire
- Relatively short haul
- Slow (65mph)
- Costs $0.23/Passenger Mile
VDI in the Datacenter
- Expensive to acquire
- Long Haul
- Fast(550mph)
- Costs $.07/Passenger Mile
24. Expensive Servers $7000/- CAPEX Cost 70 Users Per Server Thats $100 per user (Storage not included) $750/- CAPEX cost 1 User Per Desktop 25. Increasing Densities
- Moores law benefits Servers more than PCs
-
- New generation of processor = more users/server
-
- More users/server = more users/rack
-
- Morse users/rack = better cost amortization in the datacenter
-
- Net Net VDI is the most cost effective way to deliver desktops
- Corollary : Moores law will double the density of VMs per server every 18 months
26. Expensive Storage
- Yes VDI storage is expensive
-
- If you MUST use FC SAN
-
- FC Fabric to the Servers
-
- Do things the old fashioned way!
- Use VDI 2.0 Storage technologies
-
- Virtual SAN by aggregating local disk
-
- Intelligent RT Deduplication
-
- Windows aware Thin provisioning
-
- Use SATA drives and Storage Acceleration
27. Intelligent Storage choices $60.00/user Dedup, flex clone, flex cache Thin Provisioning, Dedup $70.00/user Intelligent placement, dedup Thin provisioning $140.00/user Inline dedup, caching accelerator $22.00/user 28. The math behind the CAPEX
- $10,000 /Server(Westmere + high density RAM)
- 70 Sessions / Server = $142.00/user
- $40/User Storage(netapp)
- $25/user in network & storage fabric costs
- Thin client $190/user
- Total = $397
29. Projecting for the next 5 years Year VMs/Server Cost/User #VMs/Rack 2010 70 $400 1120 2012 150 $330 2400 2014 300 $260 4800 2016 600 $150 9600 30. New deployment models 31. VDI is about at scale deployment
- Containerization
-
- Cisco/EMC vBlock like technologies
-
- Factory made VDI PODS
-
-
- Factory packaged & fully Self contained
-
-
-
- Servers+ Storage + Network Gear
-
-
-
- Just load your image & integrate with AD
-
-
- Time to install < 200 man hours for 10,000 Desktops
32. Containerization in thereal world
- Examples of Containerization
-
- Pano Express from Panologic
-
- Dell DANTE
-
- Dell flex Computing
-
- Cisco/Vmware/EMC vBlock 1 for VDI
33. New Technologies to come
- Hybrid CPU GPU architectures
-
- Better thread count and inherent parallelism( 5%)
