(the internal name is M1FS) file system or as API memory extension. Usage of MAX Data as POSIX FS does not require application modifications while API memory extension requires applications to be modified in order to utilize this functionality. MAX Data installed on Linux hosts to utilize ultra-low latency with persistent memory such as the Optane DC persistent memory (Optane DCPMM), NVDIMM or DRAM (when persistence not needed, for example for testing purposes) memory for Tier 1 and a NetApp AFF storage system for Tier 2. Optane DCPMM is the Intel brand name of products that use 3D XPoint technology and supported starting with MAX Data version 1.3. MAX FS is a Persistent Memory-based Filesystem (PM-based FS) that doesn't require application modification but also can be a Direct Access enabled File system (DAX-enabled FS) for applications with optimization for Persistent Memory using SPDK. DAX is the mechanism that enables direct access to files stored in persistent memory arrays without the need to copy the data through the page cache. MAX data have a per-server license and do not depend on CPU, Memory or storage capacity. MAX Data has two different licensing tiers: Basic and Advanced.
