  • Hyperscale design is different

    The scope of hyperscale systems requires a fundamentally different management paradigm:

    • hardware faults are common,

    • manual steps are impractical,

    • small costs add up quickly

  • Enterprise vs. Hyperscale

    OVER TWO ORDERS OF MAGNITUDE: 10 servers vs. 1000 servers

  • Flat Edges

  • Nested Centralized vs. Flat Edges

  • Fully Redundant

  • Foolishly Redundant

  • Cloud Non-Redundant

  • Fault Zones

  • Fault Zones in Hardware

  • Fault Zones in Applications

  • Stacked = Fault Zones, but Local!

  • Cloud Ready Hardware

  • Cloud Ready Hardware

    • Flexible

    • Dense

    • Efficient

    • Modular

    • Swift: per core : 4+ spindles & 2 Gb RAM

    • Nova: per core : 1 spindle & 4 Gb RAM

  • Big & Powerful vs. Small & Dense
