Chapter 2: Installation
NVM Express Connections
There are two Slimline SAS connectors located on the motherboard to support two PCIe
4.0 x4 NVMe connections. This connector provides high-speed and low-latency connections
directly from the CPU to NVMe Solid State (SSD) drives. This greatly increases SSD data-
throughput performance and signicantly reduces PCIe latency by simplifying driver/software
requirements resulting from direct PCIe interface from the CPU to the NVMe SSD drives.
