Lippis Report 218: ONUG vs. OpenStack, Open Compute and ONF

February 24th, 2014

Nick
A quick look at the board of directors of the Open Network User Group will make it obvious that ONUG is driven by some of the world’s biggest IT business leaders of networking technology. Leading financial, insurance, retail and logistics companies are all active members of ONUG. That alone sets it apart from the many other organizations with “open” in their name. In keeping with their goals, all ONUG events are intentionally kept to a manageable size so that members can meet their primary objective – which is to network other ONUG members.

Network Technology Performance Evaluation Cisco Wireless High Availability By Syracuse University’s Center for Convergence of Emerging Networking Technologies (CCENT)

Get the White Paper

February 24th, 2014

Dramatic improvements in wireless networking combined with an increasingly important role for mobile devices are driving a trend towards Wi-Fi as the primary network access mechanism in many networks. An increasing number of enterprise networks, and especially mission critical networks like healthcare, cannot afford to have application sessions drop. These trends are driving CIO’s and network managers to demand increasing levels of service resiliency. Wireless network vendors are addressing these needs by implementing new capabilities, more intelligent wireless networks that are able to prioritize mission critical traffic and dynamically recover from component failures. Cisco approached Syracuse University’s Center for Convergence of Emerging Networking Technologies (CCENT) to perform a systematic beta test, including before/after benchmarking of several applications, of its newest Wireless LAN Controller (WLC) Software (code version 7.5), which includes a new controller failover feature called Client Stateful Switchover (Client SSO). We tested this new service offering on our wireless testbed that included Cisco 5508 Wireless LAN controllers and the Cisco AIR-2602i access point.

Lippis Report 217: It’s Network Service Virtualization in the Enterprise rather than Network Function Virtualization

February 13th, 2014

NickDuring the October 2013 Open Networking User Group (ONUG) meeting, the ONUG community prioritized nine use cases based upon budget development and propensity to buy. The top three use cases were open branch office networking, open overlay or network virtualization, and integrating layer 4-7 network services to eliminate appliances into overlay networks. All ONUG use cases can be found here. Of particular note is the integrating L4-7 network services ONUG use case as its main focus is the elimination of hardware appliance, be it in the branch office and data center. A knee-jerk reaction to this use case was to define it as Network Function Virtualization or NFV. But these discussions ended with the realization that NFV will not work in the enterprise market. In this Lippis Report Research Note, I explain why and introduce the term “Network Service Virtualization.”

IBM’s New, Easy-to-Deploy Flex System Communications Module

February 12th, 2014

By Clabby Analytics

Clabby Analytics published a report, “How Cisco’s UCS Compares to IBM Flex System,” in which we concluded that IBM is out-innovating Cisco when it comes to system and communications subsystem design.

In August 2013, IBM introduced yet another communications innovation with its new Flex System Fabric SI4093 Systems Interconnect Module (SI4093). This serves as a transparent network device that simplifies layer 2 connectivity and helps IT administrators avoid possible loops by eliminating spanning tree and offers the benefits of both a pass-through and a true switch. It is preconfigured and unmanaged, but also provides cable consolidation and chassis-level switching, reducing configuration and management complexity, without giving up the performance of the EN4093R. The primary competitors for the new SI4093 are Cisco and HP. In this white paper, we provide competitive analysis across Cisco, IBM and HP.

Empowering IT Innovations and Reducing Complexity with Unified Access

February 12th, 2014

By IDC

Unfortunately, wired networking equipment and wireless networking equipment have traditionally operated in separate realms, with inconsistent features, policies, tools, and management. This increases the network administrator’s burden and drives up management costs and complexity. Cisco has recently released a new set of unified networking and management platforms designed to bring consistency and continuity to all aspects of the campus network, from the wiring closet to WLAN controllers — and everything in between. By implementing such an architectural approach to unifying wired and wireless networks, IT and network managers can introduce new levels of efficiency, gain greater levels of manageability, and improve user experience. Enabling greater levels of business innovation and growth while controlling costs, IT can demonstrate how it is driving innovative value-add to the business.

Brocade VDXTM 6740 Top-of-Rack Switch Performance and Power Test

By Lippis Enterprises

For this Lippis/Ixia evaluation at iSimCity, Brocade submitted the VDX™ 6740, which is Brocade’s flagship Top-of-Rack (ToR) switch that’s built with Brocade’s Virtual Cluster Switching (VCS™) technology, an Ethernet fabric innovation that addresses the unique requirements of highly virtualized, cloud data center environments. The line-rate, low latency VDX™ 6740 fixed configuration switch is available in two models: the VDX™ 6740 with up to 64 1/10 GbE SFP+ ports, and the VDX™ 6740T with 48 1/10 GBASE-T ports and four 40 GbE SFP+ ports. The VDX™ 6740 series switches are based on a single custom ASIC fabric switching technology and runs the feature-rich Brocade Network Operating System 4.1.0 (NOS) with VCS Fabric technology.

Arista 7500E is the most widely deployed spine switch of this new class of 288 40GbE modular switches. Over the past few months, the Lippis Report with Ixia tested the 7500E for layer 2 and 3 unicast plus multicast performance, congestion management, demanding cloud traffic performance, power consumption, the ability for its VOQ buffers to be adjustable, and if its 64-Way ECMP hash works as advertised as well as performance tested its 100GbE Line Card. If you’re building a cloud network, then you need to read this report first. In this report, we deliver the most comprehensive test and review of Arista’s 7500E modular data center spine switch.
