A+ Server AS -1114S-WTRT User's Manual
SATA (SATA0, SATA1)
The H12SSW-NT has two available SATA 3.0 ports (SATA0 and SATA1) on the motherboard.
These are standard SATA 3.0 ports.
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 PCI-E 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 resulting from direct PCI-E 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 (PCI-E
x4), for a total of sixteen SATA ports or four NVMe ports.
PCI-E M.2 Connector (M.2-C1, M.2-C2)
The PCI-E M.2 connectors are for devices such as memory cards, wireless adapters, etc.
These devices must conform to the PCI-E M.2 specifications (formerly known as NGFF).
These particular PCI-E M.2 supports M-Key (PCI-E x2) storage cards. M.2-C1 can support
a speed of PCI-E x4, when one M.2 device is installed.
