Experience and Performance of Persistent Memory for the DUNE Data Acquisition System

Emerging high-performance storage technologies are opening up the possibility of designing new distributed data acquisition (DAQ) system architectures, in which live and their processing decoupled through a element. An example these is 3D XPoint, promises to fill gap between memory traditional offers unprecedented high throughput for nonvolatile data. In this article, we characterize performance persistent devices that use XPoint technology, context DAQ one large Particle Physics experiment, DUNE. This experiment must be capable storing, upon specific signal, incoming 100 s, with 1.5 TB/s, an aggregate size 150 TB. The modular nature apparatus allows splitting problem into identical units operating parallel, each at 10 GB/s. target able dedicate single CPU those storage.
