Addressing the Needs and Concerns of Higher Speeds of Ethernet
As the industry moves towards 10 Gigabit Ethernet (10GbE) there is an increasing demand for greater performance and capabilities.  Although the market has seen the introduction of 10GbE products into the market for a few years, these products have not been able to provide full 10Gbps performance and have been quite expensive.  However, new standards and architectures are being introduced to the market that will allow the industry to not only achieve much better performance from 10GbE solutions, but to do so at much lower price points.

10GbE: Meeting the Traditional Cost and Performance Curves of Ethernet

As networks are reaching the limits of 1 Gigabit Ethernet link aggregation (LAG), IT professionals are looking to 10 Gigabit Ethernet (10GbE) as the next generation technology to be deployed. 10GbE has been in the market for several years now, but many factors have inhibited volume adoption. However, the most recent 10GbE standard, 10GBASE-T, or 10 Gigabit Ethernet over UTP copper cabling, will allow 10GbE to follow similar cost and adoption curves as to what has been realized in previous Ethernet technologies.

10GBASE-T: Short Reach Mode

A late addition to the recently released IEEE 802.3an standard for 10GBASE-T, Short Reach Mode is designed to run 10 gigabits per second (10 Gbps) with presumably less power than the full power version of 10GBASE-T. Short Reach Mode was added for cost-effective early implementations of 10 Gigabit Ethernet over copper in the data center.

This white paper addresses the technology behind Short Reach 10GBASE-T and helps guide you in properly implementing a 10GBASE-T infrastructure. Within this paper you will learn:

• What is 10GBASE-T Short Reach Mode and why was it added to the standard

• Why Short Reach Mode requires Augmented Category 6 (Cat 6A) or ISO Class F cabling

• What are the advantages and disadvantages of Short Reach Mode

• What applications are best suited for Short Reach Mode

Moving 10 Gigabit Ethernet into a Volume Platform

Two challenges exist as 10 Gigabit Ethernet (10GbE) is extended beyond its initial role.  Achieving 10Gbps on copper unshielded twisted pair (UTP) cabling is a significant technical achievement.  Meeting the application's requirements for low power is also needed for 10GBASE-T, more commonly known as 10 Gigabit Ethernet over UTP cabling, to meet its full potential.

Server Consolidation with I/O Virtualization

With mounting pressure to reduce IT costs, server consolidation with I/O virtualization is becoming a viable option for IT administrators who hope to maximize the efficiency of their server base and provide high availability computing services to their organizations. Tehuti Networks and XenSource have partnered to provide an I/O virtualization solution which not only reduces server capital expenditures by requiring fewer physical servers, but eases IT maintenance and management tasks while maintaining the high availability and performance that IT administrators need.

The Need for Host Hardware Offload

To meet the increasing needs of server, storage, and network appliance workloads, equipment manufacturers are looking for ways to accelerate packet processing to improve system performance.  This paper discusses the problems and the best approaches for addressing these issues.

Using Efficient and Cost-Effective Connectors In Performance and Power Optimized Applications
To meet the increasing needs of server, storage, and network appliance workloads, equipment manufacturers are looking for ways to increase packet processing to improve system performance.  However, for a large percentage of the market, many other parameters must be considered in addition to performance.  With increased density and thermal conditions, connectors can become one of the most significant system performance impairments.  This article addresses alternative ways equipment manufacturers can address these critical parameters.
