ABSTRACT:
Server virtualization has become a key technology for IT infra-structure owning to its flexibility and efficiency. At the same time, it also poses new challenges for I/O performance, which has become a major issue of the current virtualization. Using special hardware or pci-passthrough technique can lead to good performance but increases the cost of hardware and/or forego VM replay and live migration: these features are significant for realizing fault tolerant system and server consolidation.
Meanwhile, there is a big change in processor design paradigms. Processor vendors are turning to putting more cores in a processor rather than increasing clock frequency. Furthermore, there is an increasing interest in combining full-featured large cores with simple but low-power small cores (known as the asymmetric multi-core processor (AMP))
Considering these trends in modern processors, taking advantage of small-cores rather than costly special hardware provides new possibilities to address the I/O performance problem cost-efficiently.
Thus, my thesis will explore how to use and design small-cores to off-load I/O processing from main cores power- and cost-efficiently in order to virtualize I/O devices without special hardware.
