Intel Optane DC Persistent Memory promises up to 4.5TB per slot

At yesterday's data-centric press event, Intel revealed its upcoming Optane DC persistent memory. To be supported by most of the soon-to-be-released Cascade Lake based processors, the Optane DC persistent memory will be supported via regular DDR4 memory slots.

A system needs at least one real DDR4 module, everything else can be packed with Optane DC persistent memory, enabling up to 4.5TB of memory per DDR4 socket! Performance remains a bit of a mystery though.

Intel Optane DC persistent memory provides a new foundation for data center performance, delivering up to 36TB of system-level memory capacity when combined with traditional DRAM. Intel Optane DC persistent memory allows customers to transform critical data workloads – from cloud and databases to in-memory analytics and content delivery networks.
