At the SC17 show, Micron Technology, Inc. announced a new 32GB NVDIMM-N offering twice the capacity of existing NVDIMMs, providing system designers and original equipment manufacturers with new flexibility to work with larger data sets in fast persistent memory.

Persistent memory delivers a balance of latency, bandwidth, capacity and cost by delivering ultra-fast DRAM speeds for critical data. What sets it apart from standard server DRAM is its ability to preserve information in the event of a power loss.

NVDIMM has emerged as a critical persistent memory technology due to its ability to deliver the performance levels of DRAM combined with the persistent reliability of NAND. It reduces the bandwidth gap between memory and storage.

VMware and Dell are collaborating with Micron to increase the performance for virtualized applications.
