Today\u2019s cloud storage stack is extremely resource hungry, burning 10-20% of datacenter x86 cores, a major \u201cstorage tax\u201d that cloud providers must pay. Yet, the complex cloud storage stack is not completely o\ufb04oad-ready to today\u2019s IO accelerators. We present LeapIO, a new cloud storage stack that leverages ARM-based co-processors to o\ufb04oad complex storage services. LeapIO addresses many deployment challenges, such as hardware fungibility, software portability, virtualizability, composability, and e\ufb03ciency. 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 unmodi\ufb01ed guest VMs, at a performance that is competitive with bare-metal servers.<\/p>\n","protected":false},"excerpt":{"rendered":"
