Quad-Core Intel® "Nehalem" Xeon® processor(s)
• The new Intel® "Nehalem" architecture delivers significant performance improvements over previous technology. The memory controller is now integrated into the processor itself (rather than the chipset). It now also supports TRIPLE channel DDR3 (12x DIMMs) ECC memory rather than the previous dual channel ECC DDR2 architecture.
Another performance boost comes from introduction of Intel® Quick Path Interconnect (QPI). This provides system bus speeds up to 6.4G transfers/s and a max bandwidth of up to 25.6GB/s! It replaces the previous Front Side Bus technology and gives significantly higher bandwidths. performance and upgradeabilty.

Up to twelve "Triple Channel" fully buffered 1066/1333MHz DIMMs
• Massive memory capacity and blistering performance.

Three PCI Express* slots
• Provides expansion headroom for the future and unparalleled graphics performance.

Integrated server management
• Helps lower costs by improving baseline manageability.

Up to six SATA 3Gb/s ports
• Supporting RAID 0, 1, 5 and 10.

Optional hot swap SATA2/SAS backplane and 6 hot swap drive bays
• Supports next-generation enterprise class SAS drives or lower cost SATA2 drives.

Dual Gb Ethernet
• Increases network performance, with lower processor overhead with Intel® Advanced I/O Technology.

Quick Path Interconnect
• QPI replaces the old 'Front Side Bus' - each CPU now has its own memory controller for increased system/memory bandwidth and performance.

Dual PCI Express* X-16 graphics
• Next generation graphics interface, delivers 4.0 GB/second of graphics bandwidth per direction directly into the Intel® 5520 chipset (total bandwidth 8 GB/second), for twice the bandwidth of AGP 8X - The X20i-NX supports NVIDIA SLI and ATI CrossFire multi-GPU technologies.

PCI Express* I/O
• Serial I/O technology provides a direct connection between the MCH chipset and PCI Express* component/adapters with bandwidth up to 4 GB/second on each PCI Express x8 interface.
• PCI Express offers higher bandwidth, lower latency and fewer I/O bottlenecks than PCI-X
