SPDK (storage performance development kit, http://spdk.io) is an open source library used to accelerate the storage service (e.g., file, block) especially those service built on PCIe SSDs (e.g., 3D XPoint SSDs).

In this presentation, we would like to introduce SPDK user space vhost* solution (i.e., vhost-scsi/blk/NVMe), which can be used together with QEMU/KVM to accelerate virtio-scsi, virtio-blk and even emulated NVMe controller inside Guest OS for VMs. Relying on SPDK vhost* solution, the performance of I/Os inside VMs can be greatly improved compared (e.g., I/O IOPS increasing, I/O latency decreasing ) with an existing solution (e.g., original QEMU emulation solution, kernel vhost* solution). Moreover, SPDK vhost* solution is adopted by many cloud service providers (e.g., Alibaba).
