Abstract

For long, using software to perform memory copies has been the gold standard for applications performing memory-to-memory data movement or system memory operations. The newly released SNIA Smart Data Accelerator Interface (SDXI) Specification v1.0 attempts to change that.
 
SDXI v1.0 is a standard for a memory-to-memory data mover and acceleration interface that is extensible, forward-compatible and independent of I/O interconnect technology. Among other features, SDXI standardizes an interface and architecture that can be abstracted or virtualized with a well-defined capability to quiesce, suspend, and resume the architectural state of a per-address-space data mover.
 
This specification was developed by SNIA’s SDXI Technical Working Group, comprising of 89 individuals representing 23 SNIA member companies.
 
As new memory technologies get adopted and memory fabrics expand the use of tiered memory, SDXI Specification v1.0 will be enhanced with new accelerated data movement operations and use cases. This talk gives an overview of the SDXI’s use cases, important features of SDXI specification v1.0, and what features can be expected with new versions of the specification.
