Details
DRAM is used by Acuitys Dynamic Data Path Engine to provide read-ahead cache acceleration. Data is copied
from NVMe PCIe flash or disk (HDD or SSD) into DRAM to provide faster access to the data.

GlobalCache: Pivot3 Acuity also uses the DRAM inside each node as a high performance cache to provide an initial landing point for data as it is passed from the NVMe PCIe flash tier to the erasure coded persistent storage tier (HDD or SSD).
