Lippis Report 185: Why Software-Defined Networking and Virtualized Networking Are Inexplicably Linked

January 29th, 2012

Computer networking vendors have been increasing the speed and port density of their Ethernet switches while reducing power draw and price per port. But while Ethernet switching hardware marches on linearly, thanks to 10, 40 and 100GbE, networking software is taking a different historical path as the pace of compute and network technology evolution has diverged, with networking lagging. Highly virtualized server deployment has broken traditional networking approaches on multiple levels, for example. In response, the industry is now developing a “virtualized infrastructure” or “stack” to add network flexibility. To close the technology gap, Software-Defined Networking (SDN) is promoted as the new “organizing principle” to deliver network software and service value. While it will be, likely, years before SDN’s organizing principles take hold, I propose that these two industry activities are inexplicably linked and phased; here’s why…

January 10th, 2012

Renato Recio, IBM Fellow & System Networking CTO

Renato Recio, IBM Fellow & System Networking CTO

There are a growing number of options to make data center networking more flexible. One option is the use of Edge Virtual Bridging or EVB, which has been standardized in project IEEE 802.1Qbg and championed by IBM, HP, Brocade, QLogic, Emulex and many others. This approach extends the Virtual Ethernet Bridge or VEB sometime called Virtual Ethernet Switch (VES) used by hypervisors to connect VMs to the data center network. Renato Recio, IBM Fellow & System Networking CTO joins me to discuss IBM’s approach to virtual network infrastructure overlays and in particular its support for Edge Virtual Bridging.

Lippis Report 184: Network Services to Differentiate Next Generation of Campus Core Switches

January 9th, 2012

During the middle of 2012, a few firms will introduce core switches for campus networking. Many of these products will be based upon merchant silicon such as HP Networking’s A10500 Series Enterprise Core Switch. While these products will boast performance advantage, they will find it difficult to win share against established firms such as Cisco’s Catalyst 6500, thanks to its investment in network services. In this Lippis Report Research Note 184, we explore the importance of network services and their role in campus network design.

Lippis Report 182: Top 10 Findings: The Cloud Network Industry Test of 10/40GbE Fabrics

December 5th, 2011

The Fall 2011 Open Industry Network Performance and Power Test Report is now available. Since our Spring 2011 test, we added four products from three vendors to the 11 products from eight vendors already tested. We now have data on 15 data center switching products from nine vendors in the new report to be released after Thanksgiving. Our cloud networking test of 10 and 40GbE is now the industry benchmark for cloud networking. In fact, only those companies that are sure of their product(s) enter the test at Ixia’s iSimCity. We found that 40GbE is hard, and thus you have to give credit to the vendors that go through the testing—in this test, those vendors are Extreme Networks, Brocade and Alcatel-Lucent. These firms have high performance data center switching product that is Enterprise and Cloud service provider ready. In this Lippis Report Research Note, we share our the top 10 findings from this round of testing. Lippis Report subscribers can download the 125-page report here, free of charge.

Cloud-Ready Network Architecture

Get the White Paper

December 5th, 2011

By IBM

The cloud model isn’t about transforming IT. It’s about reinventing the way organizations do business. Organizations in every industry, regardless of size or geography, are embracing cloud computing as a way to reduce the complexity and costs associated with traditional IT approaches. Organizations that approach cloud in a tactical fashion risk adding complexity and inefficiency (not to mention security exposure) due to fragmentation, redundancy and operating silos. Conversely, organizations that embrace cloud strategically—from a business as well as IT perspective—can capture new business value through innovation, flexibility, speed, integrity and security—while reducing cost and complexity.

To deliver the cloud’s full business value, cloud-enabled data centers require speed, flexibility, cost-effective operation and scalability. This paper discusses the technical and business requirements of cloud computing, focusing on the networking layer of the cloud.

Lippis Report 181: Early Results of the Lippis Report Open Industry Cloud Network Evaluation of 10/40Gbps Ethernet Fabrics at Ixia’s iSimCity

November 7th, 2011

During the weeks of October 10 and October 31, 2011, at Ixia’s iSimCity, the Lippis Report conducted its third industry test of cloud networking data center switches operating at 10 and 40GbE. In just six short months, the industry has moved forward by breaking all previous records of data center switch speed, power consumption, port density and bandwidth. We added four products from three vendors to the eleven products from eight vendors already tested. We now have data on fifteen data center switching products from nine vendors in the new report to be released after Thanksgiving. During May 2011 Interop, we had eleven vendors provide verbal commitment to participate in this Fall industry test (remember it is free for vendors to submit products to test). As the deadline for signed agreements came, this field of eleven dropped to three because their products were simply not ready. 40GbE is hard, and thus you have to give credit to the vendors that go through the testing—in this test, those vendors are Extreme Networks, Brocade and Alcatel-Lucent. These firms have high performance data center switching product that is Enterprise and Cloud service provider ready. In this Lippis Report Research Note, we share our insights gained from testing all these products and provide the topic cloud networking industry trends taking shape now.

Understanding VXLAN Virtual-Physical-Cloud L2/L3 Networks

Get the White Paper

September 26th, 2011

By Arista Networks

VMWARE VXLAN is a new network technology developed by VMware that enables stateful VM mobility across traditional L3 routed boundaries. This enables more freedom and flexibility in matching workloads to computing power. By enabling a larger, and essentially flatter network while building on top of proven models for stable scaling of networks such as routing and equal-cost multipath forwarding, VXLAN enables any workload to be provisioned on any virtualized host, anywhere in the network that is IP reachable. No longer do routed topology decisions restrict workload mobility.

If you are a VMware and network administrator who is building virtualized networks with more than 250 VMs or want to stretch a virtual machine farm across two data centers or two or more routed domains with full workload portability, then you need to read this white paper.
