2 Legal Disclaimer Intel may make changes to specifications and product descriptions at any time, without notice. Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products, visit Intel Performance Benchmark Limitations Intel does not control or audit the design or implementation of third party benchmarks or Web sites referenced in this document. Intel encourages all of its customers to visit the referenced Web sites or others where similar performance benchmarks are reported and confirm whether the referenced benchmarks are accurate and reflect performance of systems available for purchase. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See for details. Intel, processors, chipsets, and desktop boards may contain design defects or errors known as errata, which may cause the product to deviate from published specifications. Current characterized errata are available on request. Intel Virtualization Technology requires a computer system with a processor, chipset, BIOS, virtual machine monitor (VMM) and applications enabled for virtualization technology. Functionality, performance or other virtualization technology benefits will vary depending on hardware and software configurations. Virtualization technology-enabled BIOS and VMM applications are currently in development. 64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel 64 architecture. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.

10 Typical Workloads Workload / Usage Larger Workloads Mid/Smaller Workloads Business Processing (DB, ERP, CRM, batch)* Decision Support (data warehouse, Business Intelligence) Large-scale Consolidation (including Virtualization & Multi-tier) Application Development High Performance Computing Collaboration Web Infrastructure IT Infrastructure Development/Quality Assurance E7 UCS Servers: B440 M2, B230 M2, C460, M2 C260 M2 2S Volume Servers B200 M3, C240 M3, C220 M3 Fewer/Smaller Instances/Users More/Larger Instances/Users 10 * For directional guidance only. This is not a server selection guide. Actual server sizing is a relatively complex effort involving workload characterization including such considerations as type of application, size of workload, number of users, type of transaction, SLA response times, targeted utilization, level and estimation accuracy of workload baseline/peak/growth, physical or managerial constraints, need to maintain a single state at all times to ensure all users see the same results at any given time, cost to migrate to a scale-out alternative, and system availability requirements.

11 Introducing the Intel Xeon Processor E5 Family Leadership Performance Breakthrough I/O Innovation Trusted Security Exceptional Energy Efficiency The Heart of a Flexible, Efficient Data Center Built to Scale 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.

Logic Data Buffers Address & Control Register LR-DIMM RDIMM 14 14

15 What is an LR-DIMM? LR-DIMM = Load Reduced DIMM An LR-DIMM has additional components on the DIMM which: a) Buffer the data bus pins To reduce electrical loading on the data bus b) Rank multiplication logic to make to logically reduce the number of ranks visible to the memory controller Even though there is likely four ranks physically on the DIMM Depending on the DIMM, rank multiplication can be disabled, set to 2:1 or set to 4:1 (4:1 makes a Quad ranked DIMM logically look like a single rank DIMM) More info about LR-DIMMs available here:
