Server Processor performance has increased dramatically, potentially making I/O performance a bottleneck in the data center. The Intel® Xeon® Processor E5 Family includes several I/O performance enhancements to reduce I/O latency and improve data throughput, getting data to and from the processor faster than ever before. PCI-express* 3.03 doubles the bandwidth per PCI link – greatly improving i/o throughput. Learn more >
Servers based on Intel® Xeon® Processor E5 Family offer greater PCI-express* bandwidth8, enabling greater numbers of Intel Ethernet Gigabit Server Adapters and Converged Network Adapters per server. Support for features including Intel Virtualization for Technology4 (VT-c), Virtual Machine Device Queues (VMDQ) and PCI-SIG Single Root I/O Virtualization enables optimized virtualized I/O for balanced server performance.
1. Intel® Xeon® Processor 5400 Series based system using Intel® 5000P Chipset and Intel® 6311ESB IOH supports 24 lanes PCI-Express* 1.0 at 250 MB/s per direction and 2 PCI-X slots at ~1 GB/s for a total of 14 GB/s. Intel® Xeon® Processor E5-2600 Product Family based system with Intel® Integrated I/O supports 40 lanes PCI-Express* 3.0 per processor at 1 GB/s per direction for a total of 160 GB/s.

2. Intel measurements of average time for an I/O device read to local system memory under idle conditions. Improvement compares Intel® Xeon® processor E5-2600 product family (230 ns) vs. Intel® Xeon® processor 5500 series (340 ns). Baseline Configuration: An Intel system with two Intel® Xeon® processor E5520 (2.26GHz, 4C), 12GB memory @ 1333, C-States disabled, Intel® Turbo Boost Technology disabled, SMT disabled, Rubicon* PCIe* 2.0 x8. New Configuration: Meridian system with two Intel® Xeon® processor E5-2665 (C0 stepping, 2.4GHz, 8C), 32GB memory @1600 MHz, C-States enabled, Intel® Turbo Boost Technology enabled. The measurements were taken with a LeCroy* PCIe* protocol analyzer using Intel internal Rubicon (PCIe* 2.0) and Florin (PCIe* 3.0) test cards running under Windows* 2008 R2 with SP1.

4. Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, and virtual machine monitor (VMM). Functionality, performance, or other benefits will vary depending on hardware and software configurations. Software applications may not be compatible with all operating systems. Consult your PC manufacturer.
5. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. Go to: www.intel.co.uk/content/www/uk/en/processors/processor-numbers.html for details.
6. Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products.
7. Intel does not control or audit the design or implementation of third party benchmark data or Web sites referenced in this document. Intel encourages all of its customers to visit the referenced Web sites or others where similar performance benchmark data are reported and confirm whether the referenced benchmark data are accurate and reflect performance of systems available for purchase.
