raid5f: the SPDK RAID 5 implementation

Feb 12, 2024 • Artur Paszkiewicz

RAID 5 is a popular RAID level which, similarly to RAID 1 (mirroring), protects data in the array against failure of a member drive and can improve read performance by reading from multiple drives in parallel. It is often preferred over mirroring because it “wastes” less storage capacity - the array can have many member drives but the total available capacity is always reduced only by the size of one member. Meanwhile, RAID 1 exposes the capacity of only one member. That’s 50% in the most common two-way mirror case, which provides the same level of protection as RAID 5 - protection from failure of one drive.

SPDK As IPU Firmware - Part 1

Apr 20, 2023 • Ben Walker

Welcome to the first post in a new series on SPDK as IPU firmware. 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.

New Core Maintainers For SPDK CSI

Mar 23, 2023 • Ben Walker

The SPDK project has a team of core maintainers who are responsible for providing technical oversight for the SPDK project, including final review and merging of patches into the SPDK code base. 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.

120 Million I/O Per Second with a Standard 2U Intel® Xeon® System

Feb 1, 2023 • John Kariuki

In 2013, Intel started the Storage Performance Development Kit (SPDK) project to reimagine the storage software stack. Although NVMe was still in its infancy, organizations integrating NVMe SSDs recognized the challenges they faced as the performance and efficiency of the storage software became increasingly critical to overall system performance. When Intel kicked off the SPDK Open-Source Community in 2015, a global phenomenon was born that was laser-focused on demonstrating the outstanding performance and efficiency enabled by running software designed for NVMe devices. In the beginning, the community demonstrated that it’s possible to build systems capable of millions of IOPS (I/O operations per second) using standard hardware. However, when solid-state media based on technologies like the Intel® Optane™ arrived, a whole new class of NVMe SSDs with higher throughput and an order of magnitude reduction in hardware latency the community saw an opportunity to redesign the SPDK NVMe driver. In 2019, a new SPDK NVMe driver capable of over 10 million IOPS (using a single CPU core!) was released and accompanied by a blog with deep technical insights on the techniques SPDK employs to achieved great performance. But the SPDK community is about both performance and scalability, so in 2021 we demonstrated a system that scaled to 80 million IOPS. We’re kicking off 2023 with another mind-blowing accomplishment.

BPF tracing with SPDK

Sep 28, 2021 • Konrad Sztyber

Recently, in the v21.07 release, SPDK got support for BPF tracing. It consists of a set of scripts and static probes defined within the SPDK libraries giving the user yet another way to inspect SPDK-based applications. SPDK already had a tracing library, called libtrace, for a long time. BPF tracing isn’t supposed to replace it, but rather complement it. Both have slightly different capabilities - libtrace has significantly lower overhead, but is less flexible. BPF traces, on the other hand, are more costly (they require a kernel trap), but are more robust and can even be attached dynamically, without having to define the probes in code.

The adoption of NVM Express® SSDs in the data center is unleashing performance that was unprecedented just a few years ago. Since the inception of the SPDK project, the community has demonstrated that it’s possible to build systems capable of tens of millions of IOPS (I/O operations per second) using commodity hardware. Over the last couple of years, we have demonstrated systems capable of over 10 million IOPS (using a single CPU core!), but now we’re ready to significantly advance the state of the art. Yes, 80 Million IOPS.

SPDK Test Script Hierarchy

Mar 15, 2018 • Seth Howell

As the SPDK code base has been growing, so has the collection of test scripts used by the automated build pool to perform continuous integration testing. The SPDK test bed is comprised of a hierarchy of bash scripts which make calls to example applications (located under spdk/examples) and tools written for testing (located under spdk/test). By running these test scripts and aggregating the results, the SPDK automated test pool helps contributors identify code errors or continuous integration issues introduced by their patches.

Announcing the SPDK NVMf Target

Jun 7, 2016 • Jonathan Stern

Much has already been said about NVMe over Fabrics. It was first publicly demonstrated in 2014 and the 1.0 specification is finally complete. In essence, NVMe over Fabrics (NVMf) is the NVM Express* (NVMe) block protocol tunneled through an RDMA fabric, and it has enormous potential to enable the next generation of datacenter storage development. To support broad adoption of NVMf, the Storage Performance Development Kit (SPDK) has created a reference user-space NVMf target implementation for Linux, released for community involvement via GitHub under BSD license. In parallel, community-based Linux* kernel efforts have created both a host and a target under GPL license. All three of these implementations are now released with the final 1.0 specification as of June 8, 2016.

Why SPDK?

Apr 13, 2016 • Jonathan Stern

Solid-state storage media is in the process of taking over the data center. Current-generation flash storage enjoys significant advantages in performance, power consumption, and rack density over rotational media. These advantages will continue to grow as next-generation media enter the marketplace.

NVMe API Changes

Mar 3, 2016 • Ben Walker

Over the last month, the API of the NVMe driver in SPDK has changed significantly. First, on behalf of the SPDK team, I’m sorry for breaking any existing code! SPDK is still in its infancy, so dramatic API changes will be a fact of life for the next few months. By the end of the year, we’d like to have a plan in place to manage future API changes in a more formal way. Second, I’d like to take a few moments to explain what changes were made and why we made them. I’ll stick to a mostly high level overview of the API changes for now, but we hope to produce some additional blog posts that detail each one in the future.

Introduction to the Storage Performance Development Kit

Mar 2, 2016 • Ben Walker

The Storage Performance Development Kit (SPDK) provides a set of tools and libraries for writing high performance, scalable storage applications. It achieves high performance by moving all of the necessary drivers into userspace and operating in a polled mode instead of relying on interrupts. It is primarily designed to be leveraged by OEMs and cloud service providers to optimize their storage solutions. Generally, guidelines from the related networking project DPDK should be followed. Specifically, their guide for writing efficient code almost all applies to SPDK.
