Thinking of CXL® as “just a bus” does a disservice to its true value as an opportunity to virtualize system resources. NVMe Over CXL™ is an abstraction of memory resources that combines bulk storage and memory along with persistence to provide a highly efficient combined resource available over multiple APIs including NVMe, DAX, HDM, BAEBI, etc. Data center power is already at crisis levels, largely due to the inefficiency of data movement where far below 1% of data moved is actually used. NVMe Over CXL allows for a 97% or greater reduction in data movement through the fabric, saving power and enhancing system performance. An optional data persistence mode brings NVDIMM-N style backup to CXL, improved over traditional approaches by allowing the host to define regions of persistence.
