4.6 Storage Ports
I-SATA 3.0 and S-SATA 3.0 Ports
The X11DPU has eight I-SATA 3.0 ports (I-SATA0-3, I-SATA4-7) which are supported by
the Intel C621 chipset. In addition, it also has six S-SATA 3.0 ports (S-SATA0-3, S-SATA4/
S-SATA5) that are supported by the Intel SCU. S-SATA4/5 can be used with Supermicro
SuperDOMs which are yellow SATA DOM connectors with power pins built in, and do not
require external power cables. Supermicro SuperDOMs are backward-compatible with regular
SATA HDDs or SATA DOMs that need external power cables.
NVM Express Connections
Four NVM Express ports are located on the motherboard. These NVMe ports provide PCI-E
3.0 x4 connections. P1_NVME0/1 are supported by CPU1. P2_NVME0/1 are supported by
CPU2. The NVMe ports provide high-speed low-latency connections directly from the CPU to
NVMe Solid State drives (SSDs). 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.
