  • IP Only Server

    White Papers // Nov 2016 // provided by IBM

    Present day servers must support a variety of legacy I/O devices and protocols that are rarely used in the day to day server operation, at a significant cost in board layout complexity, reliability, power consumption, heat dissipation, and ease of management. The authors present a design of an IP Only ...

  • SplitX: Split Guest/Hypervisor Execution on Multi-Core

    White Papers // Nov 2016 // provided by IBM

    Current virtualization solutions often bear an unacceptable performance cost, limiting their use in many situations, and in particular when running I/O intensive workloads. The authors argue that this overhead is inherent in Popek and Goldberg's trap-and-emulate model for machine virtualization, and propose an alternative virtualization model for multi-core systems, where ...

  • vIOMMU: Efficient IOMMU Emulation

    White Papers // Nov 2016 // provided by IBM

    Direct device assignment, where a guest virtual machine directly interacts with an I/O device without host intervention, is appealing, because it allows an unmodified (non-hypervisor-aware) guest to achieve near-native performance. But device assignment for unmodified guests suffers from two serious deficiencies: it requires pinning all of the guest's pages, thereby ...

  • Ginkgo: Automated, Application-Driven Memory Overcommitment for Cloud Computing

    White Papers // Nov 2016 // provided by IBM

    Continuous advances in multicore and I/O technologies have caused memory to become a very valuable sharable resource that limits the number of Virtual Machines (VMs) that can be hosted in a single physical server.While today's hypervisors implement a wide range of mechanisms to overcommit memory, they lack memory allocation policies ...

  • Applications Know Best: Performance-Driven Memory Overcommit With Ginkgo

    White Papers // Nov 2016 // provided by IBM

    Memory over-commitment enables cloud providers to host more virtual machines on a single physical server, exploiting spare CPU and I/O capacity when physical memory becomes the bottleneck for virtual machine deployment. However, over-commiting memory can also cause noticeable application performance degradation. The authors present Ginkgo, a policy framework for over-comitting ...

  • Adding Advanced Storage Controller Functionality Via Low-Overhead Virtualization

    White Papers // Nov 2016 // provided by IBM

    Historically, storage controllers have been extended by integrating new code, e.g., file serving, database processing, de-duplication, etc., into an existing base. This integration leads to complexity, co-dependency and instability of both the original and new functions. Hypervisors are a known mechanism to isolate different functions. However, to enable extending a ...
