Intel and Packet are working together to bring free infrastructure for testing and benchmarking with Intel® Optane™ SSDs to the developer community. This community lab is a perfect fit for the SPDK community that cares about getting the most from their storage applications. Interested in testing your SPDK application on the world’s most responsive data center SSD? Head over to Accelerate with Optane for more information, and, once you’re ready, request access. The lab will provide you with a highly capable bare metal server powered by Intel Xeon® Scalable processors, with three 750GB Intel Optane™ SSD DC P4800X and one 4TB Intel SSD DC P4500 for comparison purposes.

Come and join the 2nd annual SPDK Developer Meetup, this year hosted by NetApp in beautiful Sunnyvale CA! It’s an excellent opportunity for networking, learning and making forward progress on the code and generally making the community more productive. We’ll be covering all sorts of topics but a major theme this year will be NVMeOF (including FC support) so if you’re interested in these topics you won’t want to miss this meet-up.

Here is a recap of 2018 SPDK Summit at the beautiful Dolce Hayes Mansion, San Jose on May 15th and 16th. We had a successful event and achieved all of our goals. Thanks to the dedication and support of many contributors and great participation from SPDK community members.

All the videos from the 2018 SPDK PRC Summit are located here. Brief introduction about these videos are also included in the same folder.

Thank you all for attending the SPDK PRC Summit held at March, Beijing, China. We had a very successful SPDK summit this year with awesome content and presenters.

Today, the SPDK team is proud to announce the v18.04 release.

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.

SPDK Community meetings are open to everyone and all are encouraged to participate. Here are the details:

When submitting a new unit test, it’s not necessary to worry too much about how long the test takes because there’s no real hardware involved so the unit tests execute super-fast.

The SPDK team is proud to announce the v18.01 release.

The SPDK project has a team of core maintainers who are responsible for providing technical oversight for the SPDK project. I am pleased to announce that we are adding Shuhei Matsumoto and Changpeng Liu to the core maintainer team!

The SPDK team is proud to announce the v17.10 release, as well as the v17.10.1 release (see below for details on the changes between v17.10 and v17.10.1). This release adds a major new feature, Logical Volumes.

This week members of the growing SPDK Community met for the first ever SPDK Developer Meetup. Engineers from Massachusetts, Arizona, California, Washington, China, Japan and the United Kingdom all came together in Chandler, AZ, to meet for 2 days of discussions on everything from NVMe to vhost to the community test strategy, roadmap and upcoming improvements.

Performance Report section has been added under Documentation tab on www.spdk.io.

It’s going to be awesome! Although we’re now at capacity, please feel free to email Paul and we’ll make sure we do everything we can to accommodate you.

Come and join the very first SPDK Developer Meetup! It’s an excellent opportunity for networking, learning and making forward progress on the code and generally making the community more productive. There won’t be any presentations at this meeting, instead be prepared for the following types of activities:

The SPDK team is proud to announce the v17.07 release. This release incorporates a number of ease-of-use improvements and API cleanups.

Videos from the Intel Builders Developers Summit featuring SPDK and ISA-L held in Santa Clara on April 19th and 20th are posted here.

Please note these are static PDFs, but many of the presentations made extensive use of animations, so something may be lost in translation. There will be video available soon; links will be added in a separate post.

Today, the SPDK team is proud to announce the v17.03 release. This release features two significant new sets of components which will unlock a broader set of use cases for SPDK.

Meet with key contributors to SPDK, learn details about the latest and upcoming SPDK ingredients, and participate in roundtable discussions that will shape the SPDK community. The two day event also includes introductions to adjacent software libraries and opportunities for informal networking and private discussions.

Today we have released SPDK 16.12. This release contains the following major additions since our last release:

Much has already been said about NVMe over Fabrics. It was first publically 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.

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.

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.

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.
