4.2 Headers and Connectors

NVMe Ports (NVMe 0~11)
The H13SSW has twelve NVMe ports (2 ports per 1 MCIO x 8) on the motherboard. These
ports provide high speed and low latency 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.
SATA/NVMe Hybrid Ports (NVMe12~15, SATA 0~15)
Each SATA/NVMe hybrid port can support up to eight SATA 3.0 ports or two NVMe ports
(PCIe x4), for a total of sixteen SATA ports or four NVMe ports.
PCIe M.2 Connectors (M.2-C1, M.2-C2)
The PCIe M.2 connectors are for devices such as memory cards, wireless adapters, etc.
These devices must conform to the PCIe M.2 specifications (formerly known as NGFF). These
particular PCIe M.2 connectors support M-Key (PCIe x2) storage cards. M.2-C1 and M.2-C2
can support a speed of PCIe 3.0.
TPM/Port 80 Header
A Trusted Platform Module (TPM)/Port 80 header is located at JTPM1 to provide TPM support
and Port 80 connection. Use this header to enhance system performance and data security.
Refer to the table below for pin definitions. Please go to the following link for more information
on the TPM: http://www.supermicro.com/manuals/other/TPM.pdf.
