Lippis Report 172: A Perfect Storm Clears a Path for IBM to Re-Enter the Network Market

May 24th, 2011

Three strong trends are taking shape that are so powerful they threaten the status quo of the networking industry. These trends are more like storms than new markets; in fact they represent a major industry discontinuity. The first storm is happening now and is represented by merchant silicon for 10 and 40 GbE chips lowering the barrier of entry for new entrants in the Ethernet switch market. The second storm is much weaker but promises to be just as big, or bigger, than the first. This second storm is the creation of a software ecosystem in the networking industry, thanks to initiatives such as Software Defined Networks (SDN), OpenFlow, Arista Network’s EOS Central, etc. The third storm is the paradigm shift in enterprise IT spending thanks to mobile and cloud computing. These three storms are starting to interact and feed upon each other, forming a perfect storm in the networking industry. The perfect storm is already doing damage, as all major IT firms position product portfolios to navigate through it and prepare for its aftermath of making existing networking legacy.

Juniper Networks 3-2-1 Data Center Network Architecture: Simplifying the Data Center Network to Reduce Complexity and Improve Performance

May 24th, 2011

By Juniper Networks

Today’s data center networks are under tremendous pressure. Not only are they growing geometrically to keep pace with rapidly escalating business demands, support new application architectures and virtualized environments, and improve the overall user experience, they are expected to do so more efficiently and more cost-effectively than ever before.

The problem lies in the fact that, while everything else in the data center (applications, storage, servers) has evolved over time, the network architecture itself has not. Rather than evolve, the data center network has instead become extremely complex. This
complexity prevents the network from scaling properly, restricting available resources and limiting the ability to virtualize the data center. The Juniper Networks 3-2-1 Data Center Network Architecture delivers a strategy for simplifying the data center by flattening the existing multilayer tree structure to improve overall performance as well as the user experience.

By Force10 Networks

Storage networks present major challenges for data center switches that must be resolved to ensure fast and error-free transport of storage traffic. Force10 S60 switches are purpose-built to handle storage traffic with line-rate performance in Gigabit Ethernet and 10-Gigabit Ethernet networks.

High-Performance iSCSI SAN Architecture—A Solution’s View from Extreme Networks, Intel and NetApp

Get the White Paper

May 24th, 2011

By Extreme Networks

This white paper is targeted to enterprise and service provider IT managers who may be evaluating the ability of iSCSI SANs to satisfy the performance requirements of their most demanding storage applications. Storage application performance is dependent on more than just the performance of the storage array. The full data path and the integration with the other layers of the data center architecture must be taken into consideration. Optimizing the full data path from the server, through the network to the storage can contribute to significant improvements in performance and service levels.

This white paper and the accompanying configuration guide details the work of Intel, Extreme Networks® and NetApp to demonstrate the impact on iSCSI performance in real-world environments, using Extreme Networks CLEAR-Flow technology to help you achieve optimal iSCSI performance.

The output of the collaborative testing is presented in two separate documents:

• White Paper: provides an overview of the latest advancements around iSCSI SAN capabilities and performance, including real world, end-to-end performance results with CLEAR-Flow.

• Configuration Guide: provides a sample reference architecture with step-by-step configuration details for all the components and describes the end-to-end solution performance across a number of configurations.

Securing the Data-Center Transformation Aligning Security and Data-Center Dynamics

May 24th, 2011

By Ted Ritter Senior Research Analyst, Nemertes Research

The data center is undergoing tectonic shifts with virtualization the primary cause. Everything is moving faster within the data center—moving at the speed of virtualization—putting centers into a state of transition from physical to virtual, which can be long, complex and messy. At the same time, security models remain largely static, anchored by physical security devices. Not only does this put the organization at greater risk, it also puts in jeopardy the core benefits of virtualization. To address this, organizations need a security architecture delivering agile security and supporting the physical infrastructure, the virtual infrastructure, and all the transitional states in between the two. This requires a new security model seamlessly integrating existing security controls for physical infrastructure with comparable security controls for the virtual infrastructure. This new model requires virtualization security.

OpenFlow: The Next Generation in Networking Interoperability

May 24th, 2011

By IBM

Data centers host the computational power, storage, networking and applications that form the basis of any modern company. To reduce costs and increase the efficiency of this business-critical resource, IT organizations commonly implement new technologies and make fundamental architectural changes.

OpenFlow is an emerging technology with the potential to increase the value of data center services dramatically. Implementing OpenFlow can provide network administrators with greater control over their resources, integrated network and server management, and an open management interface for routers and switches.

Arista 7124SX 10G SFP Data Center Switch,
Arista 7050S-64 10/40G Data Center Switch,

This report details test results of Arista Networks two ToR Data Center Switches; the 24 port 7124SX and 64 port 7050S-64. All 10GbE ports are populated and tested for performance, throughput, latency and power consumption. The Arista ToR switches test results are then compared against Brocade’s VDX 6720-24, IBM BNT G8124 and G8264, Force10 Networks S-Series S4810, Hitachi Cable Apresia 15000-64XL-PSR and Voltaire Vantage 6048. In addition to the Lippis Report suite of test, we evaluate the Arista products to measure their absolute lowest latency and performance variation. You have to download this report to see what we found. It’s impressive.

Deploying and Managing Pervasive Enterprise Mobile Endpoints and Video Communications with Borderless Networks

Get the White Paper

May 24th, 2011

By Nick Lippis, the Lippis Report

IT business leaders are being confronted with a choice: either embrace users’ freedom or liberty to choose a mobile endpoint and applications that they deem appropriate to support their work, or dictate a limited number of supported mobile endpoints and applications in which employees must choose? At the center of this decision are security concerns and control as the number of mobile endpoints connecting into enterprise networks skyrocket. A larger secondary effect is that employees are downloading low cost (99 cents to $4.99) mobile applications, which is changing the mix of corporate application portfolios without IT visibility but user request for support. At the same time, video communications is expanding throughout the enterprise and the endpoints it supports. IT business leaders can avoid this difficult choice and offer users freedom to choose the mobile endpoint and applications of their liking, and still maintain security and control by deploying a Borderless Network. In this industry white paper, we review market dynamics shaping mobile computing plus video communications and how a Borderless Network offers user choice, IT management control and in the process, a more productive and agile workforce.
