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 PCIe
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
from direct PCIe interface from the CPU to the NVMe SSD drives.
