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.
These devices must conform to the PCIe M.2 specifications (formerly known as NGFF). These
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.
NVMe ports ( NVMe 0~7, 10, 11, 14, 15)
The H11SSW-iN/NT has twelve NVMe ports (2 ports per 1 Slim SAS connector). 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-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 (SATA 0-7/NVMe 8-9; SATA 8-15/NVMe 12-13)
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.
Disk-On-Module Power Connector (JSD1 & JSD2)
The Disk-On-Module (DOM) power connector at JSD1 provides 5V power to a solid-state DOM
storage device connected to one of the SATA ports. See the table below for pin definitions.

SATA (SATA0, SATA1)
The H11SSW-NT has two available SATA 3.0 ports (SATA0 and SATA1). These are standard
SATA 3.0 ports.
