Chapter 4: Motherboard Connections
4.6 Storage Ports
I-SATA 3.0 and S-SATA 3.0 Ports
The X12DPU-6 has eight I-SATA 3.0 ports (I-SATA 0-3, I-SATA 4-7) and six S-SATA (S-SATA
0-3, S-SATA 4, S-SATA 5) on the motherboard. These SATA ports are supported by the
Intel PCH C621 chipset. S-SATA 4/S-SATA 5 can be used with Supermicro SuperDOMs which
are orange SATA DOM connectors with power pins built in, and do not require external power
cables. Supermicro SuperDOMs are compatible with regular SATA HDDs or SATA DOMs that
need external power cables.
NVMe Connectors
Five NVMe connectors (P1_NVMe1/3/4/5/6), supported by Processor #1, provide five NVMe
connections. In addition, four NVMe connectors (P2_NVMe7/8/9/10), supported by Processor
#2, also provide four NVMe connections on the motherboard. Use these NVMe connections
to support high-speed PCI-E storage devices.
Note
: When installing an NVMe device on a motherboard, please be sure to connect the first
NVMe port (P1_NVMe1) first for your system to work properly.
