NVM Express
Connections Two NVM Express ports are located on the serverboard (one for each processor).
These ports provide high-speed, low-latency PCI-Exp. 3.0 x4 connections directly from the CPU
to NVMe Solid State (SSD) drives. This greatly increases SSD data-throughput performance
and signicantly reduces PCI-E latency by simplifying driver/software requirements resulted
from direct PCI-E interface from the CPU to the NVMe SSD drives.
