H12SSW-iN/NT Motherboard User's Manual
NVMe Ports ( NVMe 0/1)
The H12SSW-iN/NT has two dedicated NVMe ports (two ports on a slim SAS connector)
on the motherboard. These ports provide high-speed, low-latency PCIe 3.0 x4 connections
directly from the CPU to NVMe Solid State (SSD) drives. This greatly increases SSD data-
requirements resulting from direct PCIe interface from the CPU to the NVMe SSD drives.
SATA/NVMe Hybrid Ports (SATA 0-7/NVMe 2-3; SATA 8-15/NVMe 4-5)
Each SATA/NVMe hybrid port can support up to eight SATA 3.0 ports or 2x NVMe ports (PCIe
x4), for a total of 16 SATA ports or four NVMe ports.
TPM Header/Port 80 Connector (TPM Port)
The TPM 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.

PCIe M.2 Connector (M.2-C1, M.2-C2)
The PCIe M.2 connectors are for devices such as memory cards, wireless adapters, etc.
particular PCIe M.2 supports M-Key (PCIe x2) storage cards. M.2-C1 can support a speed
of PCIe x4, when one M.2 device is installed.
