I-SATA 3.0 and S-SATA 3.0 Ports
The X11DPT-B has seven I-SATA 3.0 ports (I-SATA0~5, I-SATA6) and six S-SATA ports
(S-SATA0~5) on the motherboard. These SATA ports are supported by the Intel C621 chipset.
I-SATA0~5 and S-SATA0~5 are located at SXB1 and are supported by CPU1.
Control Panel
JF1 contains header pins for various buttons and indicators located on the control panel at
the front of the chassis. It is designed specifically for use with a Supermicro chassis.
PCI Express 3.0 Slots
There are two PCIe slots on the motherboard for expansion cards. Several other PCIe slots
are used for proprietary cards.
•
Slot 1 (SXB3) is a standard x16 slot supported by CPU1 that can be used for a externally
accessible expansion card.
•
Slot 2 (SXB4) is a proprietary x16 slot supported by CPU2 used for a riser card that sup-
ports two externally accessible expansion cards.
Four proprietary slots, JF1/SXB1/SXB2/JF2, support the storage adapter card.
The SIOM slot is proprietary x16 for the network card.
Powered SATADOM (SuperDOM)
A SATADOM (Device-on-Disk) is located at I-SATA6 on the motherboard. I-SATA6 is used
with a Supermicro SuperDOM, which is a yellow SATADOM connector with a power pin built
in, and no external power supply is needed. Supermicro SuperDOM is backward-compatible
with a regular SATA HDD or SATADOM that requires an external power supply.
