  • Page 2: Abstract

    Abstract Virtual machine technology is the most widely understood and adopted form of server virtualization technology today. It is a powerful technology that can reduce overall costs, decrease power consumption, footprint requirements, and improve resource utilization. This technology brief describes how HP is using virtual machine technology and expanding into other areas of server virtualization such as physical-layer abstraction and management technologies for virtualization.

  • Page 3: Software-Layer Abstraction: Virtual Machines

    Figure 1. HP technologies for machine abstraction include Virtual Connect, integrated hypervisors, and integrated management. Software-layer abstraction: virtual machines In a virtual machine environment, a software layer abstracts the physical server hardware and creates one or more virtual machine instances, each with its own virtual drives, virtual network interface controllers (NICs), virtual storage controllers, virtual processors, OS, and application(s).
  • Page 4 Figure 2. In virtual machine technology, the software abstraction layer (hypervisor) abstracts the physical-layer resources. In x86 environments, there are several variations within software-layer abstraction of the server hardware, including these general categories: CPU binary translation. The hypervisor traps selected CPU instructions, such as CPU-privileged instructions and performs necessary translations to make the guest OS think it has complete control over the server hardware.

    and increases capacity expansion for customers who already use VMware’s data center virtualization and management suite, VMware Infrastructure (VI). HP SIM 5.2 and later incorporates an improved installation process and supports association and discovery for VMware ESXi. Enhanced hardware alerting and inventory management allows customers to actively receive information about the health of their ProLiant servers.

    The first implementation of the PVC is available in the integrated Citrix XenServer solution. HP is working with other partners to make use of this technology across the ProLiant portfolio as applicable.

  • Page 9: Flex-10 For Virtual Connect

    Flex-10 for Virtual Connect Flex-10 technology is the newest extension of HP Virtual Connect technology. It is a hardware-based, I/O abstraction solution that allows customers to partition a 10 gigabit (Gb) Ethernet connection, to regulate the size and data speed of each partition, and to prioritize each of those partitions. Customers can configure a single 10Gb network port to represent up to four physical NIC devices, or FlexNICs, for a total bandwidth of 10Gbps.

  • Page 10: Virtual Connect Enterprise Manager

    Virtual Connect Enterprise Manager Built on the Virtual Connect architecture integrated into every BladeSystem enclosure, VCEM is a separate application that provides a central console on a CMS to perform efficient administration of LAN and SAN connections. VCEM provides group-based management that enables administrators to rapidly configure, assign, move, and failover server-to-network connections and their workloads for up to 150 BladeSystem enclosures (2400 servers).

It integrates with vendors’ virtualization management tools, such as VMware vCenter Server (formerly known as VirtualCenter), and allows administrators to manage virtualization platforms from the same console used for physical server administration.

The combination of HP Virtual Connect and virtual machine technology provides IT administrators with new capabilities for simplifying day-to-day operations, changing server resources quickly, and increasing productivity.

  • Page 16: Appendix A: Background About Processor Ring Layers

    Appendix A: Background about processor ring layers An x86 processor includes four different ―ring‖ layers. These layers differentiate the type of instructions that the processor can execute, depending on what software is calling the instruction (Figure A1). In a typical multitasking OS, the OS operates in ―ring 0,‖ in which it has full access to all the processor and platform resources, such as memory mapping.
  • Page 17 Figure A2. In a virtual machine environment such as VMware ESX Server that uses binary translation, the guest OS operates in ring 1 or ring 3.

  • Page 18: Appendix B: Common Types Of Software-Layer Abstraction For Virtual Machines

    Appendix B: Common types of software-layer abstraction for virtual machines Binary translation With binary translation technology, the guest OS is not aware it is operating on virtualized hardware. The hypervisor manages the access of each guest OS to the physical hardware resources by masking the hardware from the guest OS.
  • Page 19 Hosted OS, kernel-layer abstraction Kernel-layer abstraction refers to a technique in which the abstraction technology is built directly into the OS kernel rather than having a separate hypervisor layer. This approach can still follow the requirements of hardware-assisted (AMD-V or Intel VT-x virtualization technologies) and paravirtualization, but removes the discrete hypervisor layer.
