CXL - SNIA on Data, Networking & Storage

How are Compute Express Link™ (CXL™) and the SNIA Smart Data Accelerator Interface (SDXI) related? It’s a topic we covered in detail at our recent SNIA Networking Storage Forum webcast, “What’s in a Name? Memory Semantics and Data Movement with CXL and SDXI” where our experts, Rita Gupta and Shyam Iyer, introduced both SDXI and CXL, highlighted the benefits of each, discussed data movement needs in a CXL ecosystem and covered SDXI advantages in a CXL interconnect. If you missed the live session, it is available in the SNIA Educational Library along with the presentation slides. The session was highly rated by the live audience who asked several interesting questions. Here are answers to them from our presenters Rita and Shyam.

Q. Now that SDXI v1.0 is out, can application implementations use SDXI today?

Using software to perform memory copies has been the gold standard for applications performing memory-to-memory data movement or system memory operations. With new accelerators and memory types enriching the system architecture, accelerator-assisted memory data movement and transformation need standardization.

At the forefront of this standardization movement is the SNIA Smart Data Accelerator Interface (SDXI) which is designed as an industry-open standard that is Extensible, Forward-compatible, and Independent of I/O interconnect technology.

Adjacently, Compute Express Link™ (CXL™) is an industry-supported Cache-Coherent Interconnect for Processors, Memory Expansion, and Accelerators. CXL is designed to be an industry-open standard interface for high-speed communications, as accelerators are increasingly used to complement CPUs in support of emerging applications such as Artificial Intelligence and Machine Learning.
