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%)

Network Attached Memory

• Shared memory that works like a SAN(10%)

Next Generation Hypervisors(10%)

• Memory deduplication

• Memory Compression

Storage Accelerators(X 5%)

• Smart VDI storage intelligence

Intelligent VDI switches(X 1%)

• Fast QOS switching

Smart load-balancers(X 1%)

• Efficient Multi Path IO from VM to storage

20,000 Desktops per Rack by 2016
