DCA Technology
This feature accelerates the performance of TOE devices. Note: A TOE device is a specialized, dedi-
cated 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. For this moth- erboard, the TOE device is built inside the ESB 2 South
Bridge chip. This feature is supported only by some types of processors (i.e., Intel Nehalem-WS 1S).
Theoptions 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 efficiency. Prefetching too fre- quently can saturate the cache direc-
tory and delay necessary cache accesses. 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],
[120]
