I-SATA 3.0 Ports
The X11DPT-L has eight I-SATA 3.0 ports (I-SATA0-7) on the motherboard. These SATA ports
are supported by the Intel® C621 chipset. I-SATA0-5 are supported by SXB1. I-SATA6/I-
SATA7 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. All these SATA ports provide serial-link signal connections.
