 Processor 7500 Series-Based platform overview of 
a fully connected four-socket, two-IOH configuration. Each Intel Xeon Processor E7-
8800/4800/2800 Product Families are connected to every other Intel Xeon Processor 
E7-8800/4800/2800 Product Families socket using three of the Intel QuickPath 
Interconnects. This enables each Intel Xeon Processor E7-8800/4800/2800 Product 
Families to be one link hop from each other and enables the support of a two-hop 
snoop protocol. The fourth Intel QuickPath Interconnect is used to connect to an IO 
Hub (IOH).
