TPM Header/Port 80 Connector
The JTPM1 header is used to connect a Trusted Platform Module (TPM), which is available from
a third-party vendor. A TPM is a security device that supports encryption and authentication in
hard drives. It enables the motherboard to deny access if the TPM associated with the hard
drive is not installed in the system.

NVM Express Connections
Two NVM Express ports are located on the serverboard (from CPU2). These ports provide
high-speed, low-latency PCIe 4.0 x4 connections directly from the CPU to NVMe Solid State
Drives (SSD). 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.
