The year of persistent storage class memory ( #SCM ) #Storage class memory (SCM)—sometimes also known as “ #persistentmemory,” or PM—provides byte-addressable persistent memory that lives on a system’s memory bus. While applications can treat SCM the same as they do existing system memory, they do so with the added benefit of persistence. It effectively blends SSD drive storage capabilities with memory bus DRAM semantics. In order to fully leverage SCM, the industry must agree on a set of interfaces, and re-architect applications to leverage them. The Storage Networking Industry Association, or SNIA, is the standards body for the storage industry. SNIA has been driving standards around persistent memory for several years, and the standards are beginning to mature. @Intel Corporation has leveraged these emerging standards into a reference implementation for working with persistent storage class memory. Both @Microsoft Corporation and the @Linux community have adopted and integrated Intel’s PEM libraries into their SCM offerings. Microsoft began supporting SCM in Windows Server in late 2017 and is shipping test builds of the next version of Windows Server today with more sophisticated support. Additionally, Microsoft now supports the technology in SQL Server 2016 SP1, in order to provide performance enhancements. Oracle Corporation is also supporting flavors of storage class memory.
