Intel
®
5520 Chipset IOH
The Intel
®
5520 Chipset component is an I/O Hub (IOH.) The Intel
®
5520 Chipset IOH provides
a connection point between various I/O components and Intel processors through
the Intel
®
QPI interface.
The Intel
®
5520 Chipset IOH is capable of interfacing with up to 36 PCI Express* lanes, which
can be configured in various combinations of x4, x8, x16, and limited x2 and x1 devices.
The Intel
®
5520 Chipset IOH is responsible for providing a path to the legacy bridge. In addition,
the Intel
®
5520 Chipset supports a x4 DMI (Direct Media Interface) link interface for the legacy
bridge, and interfaces with other devices through SMBus, Controller Link, and RMII
manageability interfaces. The Intel
®
5520 Chipset supports the following features
and technologies:
Intel
®
QuickPath Interconnect (Intel
®
QPI)
PCI Express* Gen2
Intel
®
I/O Acceleration Technology 2 (Intel
®
I/OAT2)
Intel
®
Virtualization Technology (Intel
®
VT) for Directed I/O 2 (Intel
®
VT-d2)
