  2. Agenda • What is Shared I/O? • Value of Shared I/O • Architecture for I/O Virtualization • User experience

  3. What Is Shared I/O?

  4. Dedicated I/O • Independent Operating Systems (OS) • Each OS owns a physical adapter • Each OS owns the system components to communicate to the adapter • Example: Chipset and PCI Express bus OS #1 OS #2 OS #3 I/OController I/OController I/OController

  5. Shared I/O • Independent Operating Systems (OS) • Each OS owns a virtualized I/O controller • Corresponds to a shared physical I/O controller • Virtualization Enablers control access to shared devices OS #1 OS #2 OS #3 Virtualization Enablers I/OController I/O Controller

  6. Characteristics Of Shared I/O • Multiple, independent operating systems • OSs do not coordinate with each other • Each OS has a virtual set of resources to control • Virtual resources behave and interact in manners resembling physical resources • Single resources accessed by one or more OSs • System resources, e.g., Chipset, act as access points to I/O • PCI Express acts as the connectivity from CPU and Chipset to I/O • I/O devices are simultaneously accessed by each OS • Virtualization Enablers control shared components • Isolate each OS for protection • Provide virtual view of physical shared resource • Manage functions for physical devices

  16. Shared I/O In Blades • Blades run independently • Software for OS, applications, etc. is unique for each blade • Blades have independent PCIe hierarchies • PCIe hierarchy is virtualized • Root Complex, BIOS, etc. utilize PCIe as if it was dedicated • Shared I/O components present virtualized components • Switches present multiple, virtual switches • Controllers present multiple, virtual controllers • I/O Sharing through hardware components • Switches and Controllers combine to enable sharing

  17. Each OS runs independently Virtual I/O adapters appear as physical components Virtualization Enableris a combination of software and hardware Hypervisor software PCIe Root Complex enablement, e.g., Address Protection and Translation Table (ATPT) technology Physical System is PCIe I/O solution Physical I/O comprised of Single PCIe fabric Dedicated I/O adapters Shared I/O In Virtual Machine Virtual Machine #1 Virtual Machine #2 OS #2 OS #1 Virtual I/O Virtual I/O Virtualization Enabler Physical System Physical I/O

  18. Similarities Each OS is independent Legacy OSs are fully supported PCIe I/O system Single PCIe adapter used by multiple OSs Virtual adapters appear as PCIe devices Differences Virtual Machine utilizes software Hypervisor for virtualization Blades utilize PCIe Switch for virtualization Virtual Machine may use traditional or Shared I/O enabled adapters Blades use Shared I/O enabled adapters Blade & Virtual Machine Relationship

  19. Blade & Virtual Machine Combination • Blade and Virtual Machine I/O Sharing are complementary • Component solutions for Blades benefit Virtual Machine • Management model can service both Blades and Virtual Machines OS #3 CPU CPU OS #2 Shared Ethernet NIC EnterpriseNetwork PCIe Virtualization Enablers CPU CPU OS #1 Shared I/OPCI ExpressSwitch OS #3 CPU CPU FCFabric Shared FibreChannel HBA OS #2 PCIe Virtualization Enablers CPU CPU OS #1 Blade Server Chassis

  20. Component Impact for Shared I/O

  21. User Experience

  22. Legacy OS and Applications • Shared I/O fully supports legacy OS and application software • Applies equally to Blades and Virtual Machines • Blade solution fully supports all Microsoft OS • No guest OS software introduced • Legacy software is fully contained • No new “intermediate” drivers or 3rd party software • Guest OS and applications function normally as in stand-alone server • Migration from single server to Shared I/O is seamless

  23. Devices And Drivers • Blades support legacy devices dedicated to a single blade • Virtual Machine enables software virtualization of legacy devices • Blades and Virtual Machine enable Shared I/O enabled devices to be shared by multiple OSs OS #3 Dedicated Ethernet NIC CPU CPU OS #2 EnterpriseNetwork PCIe Virtualization Enablers Shared Ethernet NIC CPU CPU OS #1 Shared I/OPCI ExpressSwitch OS #3 Shared FibreChannel HBA CPU CPU FCFabric OS #2 PCIe Virtualization Enablers Dedicated Fibre Channel HBA CPU CPU OS #1 Blade Server Chassis

  24. Management Model • Each OS manages its own virtual environment • Blades = Chipset, Virtual PCIe switch, and Virtual Adapters • Virtual Machine = Virtual Chipset and Virtual Adapters • Single control point manages common components • Blades = Switch Firmware for Switch and Shared I/O Adapters • Virtual Machine = Hypervisor for all hardware components • Blade and Virtual Machine management can stage • Blade management partitions Switch and Adapters into virtual PCIe systems • Hypervisor partitions virtual PCIe system and chipset into Virtual Machines
