multithreaded applications and provides more resources for virtual machines. The Xeon 7500 series processor
supports up to eight cores (16 hyperthreads) per processor.
The Intel 7500 chipset
Up to 2.0TB (32 GB DDR3 DIMMs) with a new (E7) Memory Cartridge
Five PCIe 2.0 slots are standard, with the choice of adding one of two optional Mezzanine modules. One option
provides PCI-X slots; the other option provides additional PCIe slots.

The DL580 G7 uses the next generation Intel Xeon Processor E7 and 7500 series processor. Its architecture departs
radically from Intel processors based on front-side bus architecture. The front-side bus uses an embedded memory
controller to produce a common share point for memory access to all processors.
The next-generation Xeon processors use NUMA (Non-Uniform Memory Access) architecture that incorporates
QuickPath Interconnect (QPI) links for point-to-point connectivity between the server’s four processors, providing
dedicated, local memory for each processor. This new architecture includes a memory buffer for each scalable
memory interfaces (SMI) in its memory subsystem, allowing for enhanced memory expansion. As a result, the DL580
G7 server offers over twelve times the memory bandwidth of the previous-generation Intel Xeon 7400 platforms and
eight times the memory footprint (2TB with 64 x 32 GB DDR3 DIMMs).
The combination of enhanced processor cores, more cores, more memory controllers, higher-speed memory and I’O
interconnect, higher memory footprint produce dramatic level of performance, posting the highest-ever jump from a
previous generation processor.
The DL580 G7’s new architecture adds new reliability, availability and serviceability (RAS) features traditionally
found in the Intel Itanium processor family. An example is the architecture for HP Memory Quarantine. Intel’s
Machine Check Recovery (MCA Recovery) is the basis of HP Memory Quarantine.
Intel’s processor advantages include:
Built on Intel's 45nm (7500 series) and 32nm (E7 series) High-K Metal Gate technology process
Up to 10 and 8 cores per processor
