PCI Expansion Slots
Each X8DTT-HF+/X8DTT-HIBXF+/X8DTT-HIBQF+ has included riser cards that
allow it to support two full-sized PCI Express 2.0 x8 expansion cards (in x16 slots),
or four total for the server.
Ethernet Ports
An Intel® network controller is integrated into each of the serverboards to support
two Gigabit LAN ports (100/1000Base-T/1000BaseTX, RJ45 output).
Onboard Controllers/Ports
Onboard I/O backpanel ports on each serverboard include one COM port, a VGA
port, two USB ports, a dedicated IPMI LAN port and two Gigabit LAN (NIC) ports. An
Infi niBand port is also included on the X8DTT-HIBXF+/HIBQF+ serverboards (the
2026TT-HIBXRF, 2026TT-HIBQRF, 2026TT-H6IBXRF and 2026TT-H6IBQRF only).
Up to four USB 2.0 (Universal Serial Bus) connections (2 Rear USB Ports and 1
Type A Header w/2 USB connections supported) are on each of the servers. There
are two sets of I/O ports included in the server (one set for each serverboard).
Graphics Controller
The X8DTT-HF+/X8DTT-HIBXF+/X8DTT-HIBQF+ features an integrated Matrox
G200eW graphics chip, which includes 16 MB of DDR2 memory.
Other Features
Other onboard features that promote system health include voltage monitors, auto-
switching voltage regulators, chassis and CPU overheat sensors, virus protection
and BIOS rescue.
Infi niBand
The 2026TT-HIBXRF, 2026TT-HIBQRF, 2026TT-H6IBXRF and 2026TT-H6IBQRF
include an Infi niBand port at DDR (dual data rate) and QDR (quad data rate)
speeds, respectively. Infi niBand is a scalable serial communications link intended
for connecting processors with high-speed peripherals. (Infi niBand requires a QSFP
connector.)
