ECU-4784 User Manual 22
2.11 Expansion PCI & PCIE
The ECU-4784 Series supports 2 standard domain I/O expansions which support up
to 2 PCI devices and 1 PCIe device. Users could also expand other functions of the
PCI & PCIe interface to meet demands.
The ECU-4784 Series offer 2 expansion slots for modularized domain I/O plug-in
cards. Through the interface card, the ECU-4784 Series can also use standard PCI
cards, PCIe cards, mini-PCI cards as well as the PCI-104 card. Due to the ECU-4784
Series being an embedded system, the power providing for the expansion slot is lim -
ited. The maximum power support for each slot is:
5 V @ 2 A
3.3 V @ 1.5 A
12 V @ 0.25 A
Support a maximum 25 W (at 50° C condition) for all slots. Before you configure all
the modules and plug-in card, please note not to exceed the power limit.
2.12 VT-D
The ECU-4784 Series support virtualization solutions which allow multiple operating
systems and applications to run in independent partitions all on a single ECU- 4784.
Using virtualization capabilities, one physical computer system can function as multi -
ple "virtual" systems. Intel
®
Virtualization Technology (Intel VT) improves the perfor -
mance and robustness of today's virtual machine solutions by adding hardware
support for efficient virtual machines. Intel
®
Virtualization Technology for Directed I/O
(VT-d) extends Intel's Virtualization Technology (VT) roadmap by providing hardware
assists for virtualization solution. VT-d continues from the existing support for IA-32
(VT-x) and Itanium
®
processor (VT-i) virtualization adding new support for I/O-device
virtualization. Intel VT-d can help end users improve security and reliability of the sys-
tems and also improve performance of I/O devices in virtualized environment. These
inherently helps IT managers reduce the overall total cost of ownership by reducing
potential down time and increasing productive throughput by better utilization of the
data center resources. For a step by step guide on how to enable VT-d and perform
direct device assignment, you can refer to as the ECU-4784 VT-D Help document for
the detailed applications.
2.13 AMT
Intel AMT is part of the Intel vPro technology offering. Platforms equipped with Intel
AMT can be managed remotely, regardless of whether they are powered up or
whether they have a functioning OS.
The ECU-4784 Series supports AMT. You can see the step-by-step guide on how to
enable AMT function in the help guide.
