Lippis Report 200: Say Goodbye to Three-Tier Spanning Tree and Hello to Two-Tier Active-Active DC Networks

October 22nd, 2012

October 8th at Ixia’s iSimCity in Santa Clara, CA, started the industry’s first public test of data center switches that boast active-active multi-path protocols such as Transparent Interconnection of Lots of Links or TRILL and SPB or Shortest Path Bridging that eliminate active-standby Spanning Tree Protocol (STP) in the design of modern computer networks. This is a big deal as active-active is one of the main designs to speed up application performance in public and private cloud computing. To flatten and scale up cloud networks, the industry is offering multiple active-active fabric options such as Cisco’s FabricPath, Juniper’s Qfabric, Brocade’s VCS Fabric, Avaya’s VENA, Arista’s SDCN, Extreme’s Open Fabric, HP’s FlexFabric, IBM’s DOVE, etc. Some of these offerings are built with standard active-active protocols such as TRILL and SPBM others are proprietary. But it’s not as complex as it sounds, because even though the public active-active test is available without fee to all vendors, only four out of 17 companies are ready and have the confidence to test their products. Those are Arista Networks, Avaya, Brocade and Extreme Networks. In this Lippis Report Research Note, we share what we have learned thus far in the Lippis/Ixia Open Industry Active-Active Cloud Network Fabric Test for Two-Tier Ethernet Network Architecture.

Advances in Wireless LANs: Meeting the Needs of Midmarket Firms

by Farpoint Group

Mobile people with mobile computers need mobile networks. Advances in basic radio technologies, very large scale integrated (VLSI) circuit technology (lower power consumption, lower cost and smaller form factors) and other radio components, network and wireless protocols, standards, reliability, security, management and, of course, total cost of ownership (TCO) have yielded sophisticated, capable, high-performance, and broadly-applied WLAN technologies and systems of today. These advances have remarkable end-user demand that continues to accelerate even today. We have thus moved to the wireless LAN as primary or default access in all key venues – businesses and organizations of all forms, the residence and public spaces. And, of course, such connectivity is more than appropriate for all applications and all forms of traffic, including time-bounded voice telephony and streaming video. The key challenge
to date has been increasing both capacity and coverage as users demand ever-higher
levels of service with an ever-growing arsenal of wireless devices. Find out how by downloading this paper.

Lippis Report 199: IBM and HP Offer Software-Defined Networking Controllers

October 12th, 2012

It’s been a few months since VMware acquired Nicira and Cisco launched Cisco ONE. But at the sleepy Interop NY show, IBM and HP expanded their SDN portfolios with the addition of SDN controllers. To date, there are just a few firms with controllers, including VMware, Big Switch Networks, Cisco, HP, IBM, NEC and Nebula. VMware put a value on SDN overlay controllers at $1.26B, which peaked the interest of every venture capitalist as well as network executive; so there’s no surprise to see more controllers entering the market. But what’s occurring is that the controller market is segmenting into OpenFlow and Overlay controllers with little to no awareness and/or interoperability between the two control plains. In this Lippis Report Research Note, we examine the new SDN controllers from Cisco, IBM, Big Switch Networks and HP with an analysis of their evolution.

A Realistic Approach To Dynamic Workload Scaling

Watch the Video

October 9th, 2012

Dave Dhillon, Product Marketing Manager, Cisco Systems

Dynamic Workload Scaling or Cloud bursting is commonly referred to as the ability to expand or contract workload between two or more virtualized data centers or cloud providers.  It sounds simple enough, but there has not been a practical approach to securely and automatically facilitate elastic IT resources in response to demand.  Cisco Systems is offering one of the most realistic approaches to cloud bursting that leverages the Nexus 7000 and its Application Control Engine or ACE load balancers.  Overlay Transport Virtualization or (OTV) is a feature of the Nexus 7000 and provides Layer 2 connectivity extension across any transport connecting two or more data centers.  ACE provides VM aware load balancing over OTV, which creates the basis for Cisco’s Dynamic Workload Scaling cloud bursting strategy.  I talk with Dave Dhillon Product Marketing Manager at Cisco Systems as we dive into Cisco’s approach to cloud bursting.

Duration: 9 minutes 59 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:01 sec: let’s start with a Dynamic Workload Scaling definition and how much demand Cisco sees for this capability?

Question 2 @ 3:46 sec:  Ok great, so let’s talk about Cisco’s Dynamic Workload Scaling approach.  It leverages ACE, OTV, Nexus 7000 and its partnership with VMware.   Can you talk to the piece parts of the approach and how they work together to deliver Dynamic Workload Scaling?

Question 3 @ 6:53 sec: Thank for solution overview, so what are the new levels of business flexibility or outcomes enabled when Dynamic Workload Scaling is implemented?

Question 4 @ 7:59 sec: How do IT business leaders implement DWS in their private clouds?
