HP ProLiant G7 c-Class server blades with Intel® Xeon® processors

How HP incorporates QuickPath technology
Bi-directional QuickPath Interconnect (QPI) links directly connect the processors with each other and
connect each processor to distributed, shared memory and the I/O chipset. Each link performs a
maximum of 6.4 gigatransfers per second (GT/s) and has a bandwidth of 12.8 gigabytes per second
(GB/s), for a total bandwidth of 25.6GB/s.
To reduce power requirements, our ROM-Based Setup Utility (RBSU)

allows QPI links to enter a low
power state when the links are not active. This feature is enabled by default. The Intel processor
determines when to put the QPI links into a low power state with minimal performance impact.
HP processor installation tool
The latest Intel 5000 series processors use a processor socket technology called Land Grid Array
(LGA). The processor package designs no longer have pins. Instead, the processor package has pads
of gold-plated copper that touch processor socket pins on the motherboard.
Because pin damage could require replacing the motherboard, HP engineers developed a tool to
simplify processor installation and reduce the possibility of damaging the socket pins (Figure 3).
