Lippis Report 220: How Open Is Cisco’s ACI?

April 1st, 2014

nick_podium2Cisco’s acquisition of Insieme Networks enables the next generation of data center automation led by Application Centric Infrastructure (ACI) and the Nexus 9000 family of switches, which is comprised of the Nexus 9300 series fixed switches and the Nexus 9500 series modular switches. In addition to offering rich programmability features, industry-leading layer 2 and layer 3 forwarding, and advanced behaviors, such as VxLAN routing, the Nexus 9000 switches run in a fabric mode commonly referred to as ACI. ACI is an architecture that enables the automated deployment of applications across the network using Application Network Profiles. These profiles use a common declarative policy language that automates network configuration. The policy creates an application dependency map that spans applications, compute, storage and networking across data center, campus and WAN to enable cross-functional application troubleshooting and performance optimization. Critical to expanding ACI is the new Opflex protocol that enables an open source community to leverage ACI for policy-based automation for all data center devices (more on this below). ACI delivers the complete ability to provision, manage and monitor applications in a fully automated workload creation world. This is the Holy Grail of IT as it enables business resiliency and lowers OpEx. But the two big questions that many have been asking are: “How open is ACI, and can I trust it?”

Brocade’s New VDX 6740 Performance Test Result Record

April 1st, 2014

gautamRoyBrocadeNewVDX6470PerformanceTestResultRecordFor the 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. We populated and tested the switch’s 10 and 40 GbE ports for performance and power consumption. In this podcast, Gautam Roy, Senior Product Marketing Manager at Brocade, joins me to review the VDX 6740’s test results.

EOS: The Next Generation Extensible Operating System

April 1st, 2014

By Arista Networks

Performance, resiliency and programmability across the entire network are now fundamental business requirements for next generation cloud and enterprise data center networks. Arista Networks has designed and delivered EOS (Extensible Operating System), a Linux-based network operating system, to address these requirements. EOS is a robust, programmable and innovative system, featuring a single software image that runs across the entire portfolio of Arista’s network switches. This guarantees consistent operations, workflow automation and high availability, while significantly reducing data center operational expenses. This whitepaper discusses current network operating systems and explains how Arista’s EOS architecture uniquely supports next generation data centers.
