Yet, the complex cloud storage stack is not completely offload-ready to today’s IO accelerators. We present LeapIO, a new cloud storage stack that leverages ARM-based co-processors to offload complex storage services. LeapIO addresses many deployment challenges, such as hardware fungibility, software portability, virtualizability, composability, and efficiency. It uses a set of OS/software techniques and new hardware properties that provide a uniform address space across the x86 and ARM cores and expose virtual NVMe storage to unmodified guest VMs, at a performance that is competitive with bare-metal servers.}, url = {http://approjects.co.za/?big=en-us/research/publication/leapio-efficient-and-portable-virtual-nvme-storage-on-arm-socs/}, }
