No matter where an IT architect looks they are confronted with scaling issues and many times one solution creates another problem. To address increasing VM density many are expanding broadcast domains with flatter 2-tier architectures only to get bogged down in broadcast issues. To scale virtualized networks the industry offers VXLAN, but that moves L2 scaling into a multicast-scaling problem. Software-Defined Network and in particular OpenFlow offers a good approach for provisioning and control but introduces flow oriented architecture scaling issues of its own. I discuss scaling challenge with Shehzad Merchant Chief Technology Officer at Extreme Networks.

Question 2 @ 3:50 sec: Forwarding table architecture and size define logical networking scale. Extreme recently introduced UFT or Unified Forwarding Table. What is it and how does it work?
Question 3 @ 6:35 sec: Extreme has partnered with Big Switch Networks to address network visualization scale via its Big Tap and Big Virtual Switch. Can you talk to this solution?
Question 4 @ 8:51 sec: Can you sum up all the initiatives that Extreme has under way to deliver on its Open Fabric architecture for clo
The edge network has to be more intelligent to support Bring Your Own Device or BYOD as well as existing wired desktops. But many SecOps groups would rather deny mobile access than allow it due to security threats, thanks to lack of visibility or device, user and location information mobile devices offer upon network access. To mitigate this concern, Extreme Networks launched its Intelligent Mobile Edge Network initiative including Ridgeline 3.1 to provide SecOps context-aware identity information and application visibility for mobile and fixed endpoints entering the network. In addition a new line of edge switches called the Summit x440 works closely with WiFi equipment to increase 802.11n performance and scalability. Huy Nguyen, Sr. Director of Product management at Extreme, joins me as we discuss the fundamental changes in edge networking thanks to BYOD and Extreme’s approach to securing mobile devices so corporations can gain the productivity gains of user device freedom.
During the Fall 2011 edition of the Open Industry Network Performance & Power Test for Cloud Networks Evaluating 10/40 GbE Switches, Extreme Networks submitted its X8 Data Center Switch. We tested this switch populated with 192-40GbE ports, the highest density in the industry. We found the lowest latency and power consumption to date in the industry.
High Performance Computing Clusters (HPCC) are no longer exclusive to the scientific community. “Big Data Analytics” are big business. Financial services, retail and manufacturing all require real-time analysis for real-time business decisions. This white paper discusses the cluster interconnect, its importance to HPCC and a lowest latency, higher performing solution from Extreme Networks®.
Colleges and universities have made large investments in wiring dormitories and residence halls. However, today’s students are using mobile devices with no wired Ethernet connector. Today’s laptops, tablets and smartphones rely on 802.11n Wi-Fi. Campus administrators require a simple and effective way to deliver wireless service quickly; leveraging existing wired investment to keep cost down. It is also beneficial to maintain a wired connection in the rooms, delivering both wired and wireless service. Extreme Networks Altitude 4511 uniquely enables administrators to meet student demands while achieving business goals, with a cost-effective solution that is a snap to install and can scale as needs grow.
Today’s mobile users require consistent Wi-Fi with high throughput, but traditional ceiling-mounted access points can make it challenging to extend 802.11n into facilities with many rooms, walls and other obstructions. The combination of the Altitude™ 4511 wallplate access point, fortified with Motorola radio technology and intelligent switches from Extreme Networks, makes it faster and easier to deploy and manage a converged wired and wireless network edge with security and high performance
that’s right where the mobile users are located for better access and service.
The Lippis Report has conducted three open industry test of 10 and 40GbE data center fabric switches at Ixia’s iSimCity. Michael Githens of Ixia interviews Nick Lippis of the Lippis Report to look back on what we have learned after testing eleven products from nine vendors including Alcatel-Lucent, Arista Networks, Brocade, Dell/Force10, Extreme Networks, Hitachi Data Systems, IBM, Juniper Networks and Mellanox/Voltaire. We then look forward as to what the industry will be serving up in 2012 for data center fabrics.

While the Lippis Report test were being conducted of the Extreme Networks BlackDiamond® X8 Core and Summit® X670V ToR data center fabric switches at Ixia’s iSimCity, Darius Goodall, Product and Technical Marketing of Extreme joined me to discuss the firm’s latest product investment. We talk cloud network architecture and what’s unique about the new X8 and X670V.

Several technology inflection points are coming together that are fundamentally changing the way networks are architected, deployed and operated, both in the public and private cloud. From performance, to scale, to virtualization support and automation to simplified orchestration, the requirements are rapidly changing and driving new approaches to building data center networks. This white paper does an excellent job at articulating cloud-scale network architecture via an open fabric that accounts for all major industry trends.
Extreme Networks has added to its Extreme Open Fabric cloud networking portfolio by introducing a unique 10/40GbE ToR switch in its Summit X670; an ultra low latency switch thanks to a PHY-less design and cut-through switching. For the core, the new BlackDiamond X8 is a massive core switch built for virtualized infrastructure. It boasts 192x40GbE or 768 10GbE ports, 5 Watts/10GbE port power consumption, 128K VMs, high reliability and compact size being only one-third of a rack or 14.5 RUs. In this Lippis Report podcast, I talk with Shehzad Merchant, VP of Technology at Extreme Networks, about Extreme’s new cloud networking products and the architecture it now offers to IT architects and designers.
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.

Say “identity management” and what usually comes to mind is LDAP directories, strong authentication and Single Sign-On (SSO) systems. These technologies are used for access to Windows networks, e-mail and other internal applications. Generally, network identity is associated with IP and MAC addresses, VLAN tags and subnets. It also plays a role in security in areas like device authentication, VPNs and IPSEC. ESG believes that the historical differences and separation between application- and network-layer identity no longer make sense. This white paper describes why and proposes a new model for identity-aware networking.
Server virtualization brings with it a set of network operational challenges: from configuration challenges around Virtual Machine (VM) switching to managing virtual machine mobility, to providing VM location and inventory in the network. There are few tools available to the network administrator that provides visibility, control and insight into the VM environment until now. Extreme Networks® XNVTM provides network-level visibility and control of the server VM environment in a hypervisor-agnostic manner and without requiring any changes to the server virtualization operating environment.
