Deconstructing the brian paradox Deconstructing the brian paradox Presentation Transcript

  • Deconstructing the Brian Paradox VDI is here ready or not The manic Logic of VDI Chetan Venkatesh CTO & Founder Brian Madden Guru Briforum 2010
  • What is Brian’s 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
  • DESKTOP COMPUTING MODELS CIRCA 2009 Physical Desktop Physical Desktop on Virtual Storage TS based desktop & remote applications Virtual Desktop on VDI Virtual Desktop on Type 2 Client Virtual Desktop on Type 1 Client
    • 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* @
  • 3 themes to explore
    • How personal computing has changed
    • Moore’s law and its impact on the Datacenter
    • Deployment models
  • “ Personal” Computing is different now! cp/m Ms-dos netware Windows 95-2000-XP Linux KDE/Gnome Mac OSX iphone – iPad Android
  • Users don’t care about our version of “Personalization”* * At least not the way we think about it today
  • The web changes personalization FB Connect/OpenSocial Roaming Profile/Appsense/Res Entitlements Policies Security Application subscriptions profile
  • The web changes Apps That’s a cool App! I’m going to subscribe to it
  • And makes the Desktop less important Rich Profile & Context of what I like & what I trust Rigid set of policies On what I can do Social Cloud Enterprise Cloud
  • Vectors for 2015
    • Rich Content & social applications will hasten the demise of relic PCs from being the primary computer
      • Consumption oriented devices will be the users primary “personal computer” – i.e. tablets, netbooks and smart phones
      • Windows will become middleware – simply a connection between users and enterprise apps. Windows is a place to run apps
    > +
  • 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
  • Vectors for 2015
    • Users will no longer care about Application installation & management
        • iTunes, Android market & Citrix Dazzle will be interfaces to application provisioning
  • An uncharitable comparison = PC PC + Client hypervisor (type 1|2) NOTHING HAS FUNDAMENTALLY CHANGED
    • No CAPEX Proposition
    • Marginal OPEX value
    • Frankenstein PC
  • The PC era is dead. We need closure with it, its architecture and all attempts to Frankenstein it with Client Virtualization
  • Moore’s law & the datacenter
  • 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
    • Moore’s law
      • Moore’s law has more amplitude in the datacenter
  • Dematerialization & liquidity
    • Dematerialization is the transformation of physical objects into mental/thought/logical objects
    • Dematerialization creates liquidity and opportunities for arbitrage
    Dematerialization aka virtualization
  • A NEW ARCHITECTURE FOR DESKTOP COMPUTING
    • The Rack is the new computer
      • It is now the NEW fundamental element of compute
    • 10G Ethernet 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 the new OS
      • Memory Page Sharing, Primary Storage Deduplication, CDP, data mirroring, DR are new primary subsystems of the new Datacenter OS. Many of these are astronomical in cost/complexity to do on the PC.
  • 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
  • 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 (or accessible from everywhere) - where would Enterprise IT run the VM and why?
    Datacenter
    • Fine grained control
    • Tighter Security
    • Dynamic Capacity
    • Disaster recovery and & Business Continuity
  • Common VDI myths
    • Expensive Servers
    • Expensive Storage
    • Expensive Datacenter
      • Power/cooling/real estate
  • 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
  • Expensive Servers $7000/- CAPEX Cost 70 Users Per Server That’s $100 per user (Storage not included) $750/- CAPEX cost 1 User Per Desktop
  • Increasing Densities
    • Moore’s 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 : Moore’s law will double the density of VMs per server every 18 months
  • 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
  • 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
  • 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
  • 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 $150 9600
  • New deployment models
  • VDI is about at scale deployment
    • Containerization
      • Cisco/EMC vBlock like technologies
      • Factory made VDI PODS
        • Factory packaged & fully Self contained
        • Servers+ Storage + Network Gear
        • Just load your image & integrate with AD
      • Time to install < 200 man hours for 10,000 Desktops
  • Containerization in the real world
    • Examples of Containerization
      • Pano Express from Panologic
      • Dell DANTE
      • Dell flex Computing
      • Cisco/Vmware/EMC vBlock 1 for VDI
  • New Technologies to come
    • Hybrid CPU GPU architectures
      • Better thread count and inherent parallelism ( 5%)
    • Network Attached Memory
      • Shared memory that works like a SAN (10%)
    • Next Generation Hypervisors (10%)
      • Memory deduplication
      • Memory Compression
    • Storage Accelerators (X 5%)
      • Smart VDI storage intelligence
    • Intelligent VDI switches (X 1%)
      • Fast QOS switching
    • Smart load-balancers (X 1%)
      • Efficient Multi Path IO from VM to storage
    20,000 Desktops per Rack by 2016 <50$ per User for Datacenter Infrastructure
  • Closing thoughts
    • The move to the cloud is comparable to urbanization
      • Opportunity to create new shared infrastructures that make people more productive & efficient
    • VDI is not just the sum composite of knee jerk reactions to PC management
      • A long term transformational vector
      • The natural evolution of computing
      • Something that cant be ignored
  • Q&A & Discussion
