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.
Please go to the following link for more information on TPM:
manuals/other/TPM.pdf.
NVM Express Connections
Two NVM Express ports are located on the motherboard (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 significantly reduces PCI-E latency by simplifying driver/software requirements resulted
from direct PCI-E interface from the CPU to the NVMe SSD drives.
PCI-E M.2 Connector
The PCI-E M.2 connector is for devices such as memory cards, wireless adapters, etc.
These devices must conform to the PCI-E M.2 specifications (formerly known as NGFF). This
particular PCI-E M.2 supports M-Key (PCI-E x2) storage cards only.
SATA Ports
The H11DSi-NT has eight available SATA 3.0 ports (CPU1-SATA0~3, CPU2-SATA0~3) on
two iPASS connectors that are supported by CPU1 and CPU2. These use an iPASS breakout
cable to support 4 ports per connector. There are also two SATA ports (P2-SATA0, P2-SATA1)
that are supported by CPU2 and also provides integrated DOM (Disc On Module) power.
