•Next Generation Servers With Integrated Ethernet
Agenda

62. 62
Creating Server Optimized Network Services
Characteristics of optimized network services –beyond just virtualization
-Design point is Private Cloud
-Current goal is full utilization of physical resources with VMs
5-50 VMs per physical host can be typical
New requirements for high VM density for Private Cloud
1.Lower network and storage CPU overhead
2.Higher throughput requirements due to high VM density
3.Low variance for latency & throughput (95thpercentile)
4.Transparent hardware fault tolerance for network
5.VM workload isolation

•Excellent Performance
-Near line rate performance for both small and large IOs w/ RDMA
-Very low CPU utilization w/ RDMA

SMB3 and SMB Direct Workloads
SMB3 Workloads
•Storage for Hyper-V, SQL Server, HPC
•Storage for desktops/laptops/slates (LAN/WAN)
•Hyper-V Live Migration between hosts
The Design Point is Private Cloud
•Almost all IOs are small (<64 KB)
-Throughput is significantly less due to CPU saturation
-RDMA enables near line rate with small IOs
SMB3 Multi-Channel Enables Linear Scaling
•Linear 10GbE scaling with TCP/IP
•4300 Mbps with 4x10GbEhttp://go.microsoft.com/fwlink/p/?LinkId=227841
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.

What is Remote Direct Memory Access (RDMA) ?
RDMA
•Accelerated IO delivery model which works by allowing application software to bypass most layers of software and communicate directly with the hardware
RDMA benefits
•Low latency
•High throughput
•Zero copy capability
•OS / Stack bypass
RDMA Hardware Technologies
•iWARP: RDMA over TCP/IP
•RoCE: RDMA over Converged Ethernet
•InfiniBand*
RDMA support in Windows*network stack
•New Network Direct Kernel-mode Provider Interface (NDKPI), which abstracts the hardware

Risk Factors
The above statements and any others in this document that refer to plans and expectations for the second quarter, the year and the future are forward- looking statements that involve a number of risks and uncertainties. Words such as “anticipates,” “expects,” “intends,” “plans,”“believes,” “seeks,” “estimates,” “may,” “will,” “should” and their variations identify forward-looking statements. Statements that refer to or are based on projections, uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel’s actual results, and variances from Intel’s current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers the following to be important factors that could cause actual results to differ materially from thecompany’s expectations. Demand for Intel's products is highly variable and, in recent years, Intel has experienced declining orders in the traditional PC market segment. Demand could be different from Intel's expectations due to factors including changes in business and economic conditions; consumer confidence or income levels; customer acceptance of Intel’s and competitors’ products; competitive and pricing pressures, including actions taken by competitors; supply constraints and other disruptions affecting customers; changes in customer order patterns including order cancellations; and changes in the level of inventory at customers. Intel operates in highly competitive industries and its operations have high costs that are either fixedor difficult to reduce in the short term. Intel's gross margin percentage could vary significantly from expectations based on capacity utilization; variationsin inventory valuation, including variations related to the timing of qualifying products for sale; changes in revenue levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; excess or obsolete inventory; changes in unit costs; defects or disruptions in the supply of materials or resources; and product manufacturing quality/yields. Variations in gross margin may also be caused by the timing of Intel product introductions and related expenses, including marketing expenses, and Intel's ability to respond quickly to technological developments and to introduce new products or incorporate new features into existing products, which may result in restructuring and asset impairment charges. Intel's resultscould be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Intel’s results could be affected by the timing of closing of acquisitions, divestitures and other significant transactions. Intel's results could be affected by adverse effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust, disclosure and other issues, such as the litigation and regulatory matters described in Intel's SEC filings. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from manufacturing or selling one or more products, precluding particular business practices, impacting Intel’s ability to design its products, or requiring other remedies such as compulsory licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel’s results is included in Intel’sSEC filings, including the company’s most recent reports on Form 10-Q, Form 10-K and earnings release.
