Storage Performance Development Kit (SPDK)

Linters Docker Travis License Pulls Last Release GitHub stars GitHub Contributors

The Storage Performance Development Kit (SPDK) provides a set of tools and libraries for writing high performance, scalable, user-mode 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, which avoids kernel context switches and eliminates interrupt handling overhead.

This project contains Dockerfile for https://github.com/spdk/spdk

I Want To Contribute

This project welcomes contributions and suggestions. We are happy to have the Community involved via submission of Issues and Pull Requests (with substantive content or even just fixes). We are hoping for the documents, test framework, etc. to become a community process with active engagement. PRs can be reviewed by by any number of people, and a maintainer may accept.

See CONTRIBUTING and GitHub Basic Process for more details.
