Intel I/OAT
The Intel I/OAT (I/O Acceleration Technology) signifi cantly reduces CPU over-
head by leveraging CPU architectural improvements, freeing the system resource
for other tasks. The options are Disabled and Enabled.
DCA Technology
Select Enabled to use Intel's DCA (Direct Cache Access) Technology to improve
data transfer effi ciency. The options are Enabled and Disabled.
DCA Prefetch Delay
A DCA Prefetch is used with TOE components to prefetch data in order to shorten
execution cycles and maximize data processing effi ciency. A TOE device is a
specialized, dedicated processor that is installed on an add-on card or a network
card to handle some or all packet processing of this add-on card. Prefetching
too frequently can saturate the cache directory and delay necessary cache ac-
cesses. This feature reduces or increases the frequency the system prefetches
data. The options are [8], [16], [32], [40], [48], [56], [64], [72], [80], [88], [96],
[104], [112], and [120].
Intel VT-d
Select Enabled to enable Intel Virtualization Technology support for Direct I/O
VT-d by reporting the I/O device assignments to the VMM (Virtual Working
Memory) through the DMAR ACPI Tables. This feature offers fully-protected
I/O resource sharing across Intel platforms, providing greater reliability, security
and availability in networking and data-sharing. The options are Enabled and
Disabled.
