NVDIMM is a standard for allowing non-volatile memory to be exposed to as normal RAM, which can be directly mapped to guests. This simple concept has the potential to dramatically change the way software is written; but also has a number of surprising problems to solve. Furthermore, this area is plagued with incomplete specifications and confusing terminoligy.
This talk will attempt to give an overview of NVDIMMs from an operating system perspective: What the terminology means, how they are discovered and partitioned, issues relating to filesystems, a brief description of the functionality available in Linux, and so on. It will then describe the various issues and design choices a Xen system has to make in order to allow Xen systems to use NVDIMMs effectively.
