connections, provide hot-plug support via a dedicated SMBus interface. This feature is only
available for a Supermicro complete system with an SMCI-proprietary NVMe add-on card
and cable installed. See the table below for pin definitions.
I-SATA 3.0 and S-SATA 3.0 Ports
The X11DPU-XLL has eight I-SATA 3.0 ports (I-SATA0-3, I-SATA4-7) and six S-SATA ports
(S-SATA0-3, S-SATA4, S-SATA5). These SATA ports are supported by the Intel C621 chipset.
I-SATA0-3 are supported by the CPU2 PCI-E 3.0 x16 slot on SXB2 and S-SATA0-5 are
supported by the CPU1 PCI-E 3.0 x8 slot on SXB1. S-SATA4/S-SATA5 can be used with
Supermicro SuperDOMs, which are yellow SATA DOM connectors with power pins built in
that do not require external power cables. Supermicro SuperDOMs are backward-compatible
with regular SATA HDDs or SATA DOMs that need external power cables.
