On behalf of the SPDK community I’m pleased to announce the release of SPDK 20.07!

This release contains the following new features:

  • SPDK CSI driver: Added CSI driver to bring SPDK to Kubernetes storage through NVMe-oF or iSCSI. Supporting dynamic volume provisioning and enabling Pods to use SPDK storage transparently. This feature is considered experimental. See SPDK-csi repository for more details.
  • Acceleration Framework: Added commands for compare, dualcast, crc32c, along with batching support for all commands in all plug-ins. See accel_fw for detailed information.
  • I/O abort: Added support for aborting I/O commands to NVMe, NVMe-oF and Bdev layers.
  • Env PCI drivers: Added env APIs to provide greater flexibility in registering and accessing polled mode PCI drivers.
  • RDMA library: Added rdma library providing an abstraction layer over different RDMA providers. Two providers available are verbs and mlx5 Direct Verbs.
  • spdk_dd: Added an application for copying data to/from files and SPDK bdevs efficiently.
  • bdevperf config: Added support for configuration files similar to FIO, to allow benchmarking more complex use cases. See bdevperf for more details.
