The Storage Performance Development Kit (SPDK) provides a set of tools and libraries for writing high performance, scalable, user-mode storage applications.
On behalf of the SPDK community I’m pleased to announce the release of SPDK v23.05!
Continue...Welcome to the second post in our series on SPDK as IPU firmware. The previous post laid the groundwork for using SPDK on an IPU. Now we’re going to focus on enabling inline, block-level encryption in a more efficient way. If it isn’t fresh in your mind, take a moment to review our example scenario from the last post. We’ll start from there.

For those not familiar with the term Infrastructure Processing Unit (IPU), these are PCIe cards attached to a host system that offload “infrastructure” work, usually for a cloud or hyper-converged service provider. In terms familiar to SPDK developers, these cards typically have some hardware that’s capable of presenting what appear to be physical NVMe or virtio-blk/scsi devices to the host system, but then may forward any I/O sent to that device over the network.

As the SPDK project continues to grow, the core maintainer team also needs to grow by adding contributors who are already demonstrating technical skill and leadership within the project. SPDK has seen increased interest in orchestration, especially the SPDK CSI Kubernetes plugin, so we are pleased to announce that Yibo Cai and Antti Kervinen are joining the core maintainer team with a specific focus on the spdk-csi project. Yibo and Antti will be responsible for helping define and refine the architecture and design for spdk-csi, as well as being primary reviewers for all incoming patches.
