NVM Express
Connections Two NVM Express ports are located on the serverboard. These ports provide
high-speed, low-latency PCIe 4.0 x8 connections directly from the CPU to NVMe Solid State
(SSD) drives. This greatly increases SSD data-throughput performance and significantly
reduces PCIe latency by simplifying driver/software requirements resulted from direct PCIe
interface from the CPU to the NVMe SSD drives.
