Intel RAID Key Header
The JRK1 header allows you to enable RAID functions for NVMe connections. Refer to the
table below for pin definitions.
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 significantly reduces PCIe latency by simplifying driver/software
requirements resulting from direct PCIe interface from the CPU to the NVMe SSD drives.
