This is the second of a five part series on IBM’s Open Data Center Interoperable Network or program and its DOVE or Distributed Overlay Virtual Ethernet.  I talk with Renato; IBM Fellow and System Networking Chief Technical Officer about IBM’s approach to virtual network overlays called DOVE.

Duration 16 minutes and 20 seconds:

 

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:22: Renato would you like to add anything to my virtual network overlay discussion in the intro that’s unique to IBM?

Question 2 @ 4:46: What is DOVE, a switch, software, etc?

Question 3 @ 7:42: How are IBM’s virtual network overlays created and managed?

Question 4 @ 9:59 How are virtual networks transported over the physical L2/3 network?  Does IBM support hybrid mode?

Question 5 @ 11:59: There are multi-tenant clouds, hybrid clouds and large-scale private clouds or data centers that would benefit from virtual network overlays.  Which use cases does IBM see as virtual network overlays offering the most value today?

Question 6 @ 14:29: How do IT business leaders start to implement IBM’s virtual network overlay?

January 7th, 2013

Dr.Casimer DeCusatis

This is the first of a five part podcast series on IBM’s Open Data Center Interoperable Network or ODIN program and its DOVE or Distributed Overlay Virtual Ethernet initiative.  In this podcast I talk with Dr. Casimer DeCusatis IBM Distinguished Engineer and IBM System Networking’s chief technical officer for strategic alliances about IBM’s expanded approach to data center networking and the gains anticipated by IBM customers.

Duration 10 minutes and 05 seconds:

 

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:16: Let’s start with a discussion about Open Data Center Interoperable Network; what is it and what problem(s) does it seek to solve?

Question 2 @ 3:37: What benefits will IT leaders gain as they start an ODIN journey.

Question 3 @ 5:13: Is ODIN an architecture and an approach to networking or a way for IBM to communicate to the market a set of product/service investments it’s making?

Question 4 @ 7:13: How does ODIN prepare a data center or cloud for elastic compute, storage and network provisioning of resource pools that can be rapidly partitioned into desired configuration?

Building a World-class Data Center Network Based on Open Standards

by IBM System Networking

Data centers are undergoing a major transition toward a smarter, more dynamic infrastructure. More flexible IT architectures are emerging to address the demands of current business applications and new areas, such as cloud computing, multitenancy, bring your own device (BYOD), big data, and analytics. As part of the dynamic infrastructure trend, the role of data center networks is also changing. It is causing businesses to re-evaluate their current networks, which were never designed to handle modern workloads and applications. IBM’s Open Data Center Interoperable Network or ODIN addresses many of the key problems faced by modern data networks, including automation, integration, and management. Compared to classical Ethernet architectures, ODIN fabrics have several distinguishing benefits, which are discussed in this white paper.

Create a flattened, converged, virtualized, standards-based network
by IBM System Networking

An open data center with an interoperable network is a flat, converged, virtualized data center network that is based on open industry standards. Instead of under-utilized devices, multi-tier networks, and complex management environments, the modern data center is characterized by highly utilized servers running multiple VMs, flattened, lower latency networks and automated, integrated management tools. New software-defined network approaches (including overlay networks and OpenFlow standards) greatly simplify the implementation of features such as dynamic workload provisioning, load balancing, and redundant paths for high availability and network reconfiguration. Further, high-bandwidth links between virtualized data center resources may extend across multiple data center locations to provide business continuity and backup/recovery of mission-critical data. A highly virtualized data center offers greater resource utilization and lower costs. This new network infrastructure also simplifies management and addresses network issues such as latency, resilience, and multi-tenant support for public and private cloud environments. By taking advantage of IBM’s Open Interoperable Networking (ODIN) design approach, enterprises can design a cost-effective and manageable data center that fully uses the potential of virtualization, and gives customers the flexibility to migrate to federated data centers, in which computing, storage, and net-work resources may be treated as dynamically provisioned resource pools that can be rapidly partitioned into any desired configuration.

August 27th, 2012

Rakesh Saha, Director of Product Management for Advanced Technologies at IBM System Networking and Samrat Ganguly, Chief Network Architect for NEC’s ProgrammableFlow join me to help us make sense of the fast paced evolution of Software-Defined Networking and predict its future.

Duration: 12 minutes and 26 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:19 sec: Rakesh, There are a few approaches to SDN including overlay virtual networks, OpenFlow control of physical and virtual switches plus a hybrid. How do you see these implementations evolving over time?

Question 2 @ 5:10 sec: Samrat, There are a range of protocols to use for the overlay of virtual networks to tunnel through physical L2/3 networks, such as GRE, VXLAN , NVGRE, etc. How will this space evolve?

Question 3 @ 6:34 sec: Rakesh, There’s discussion in the industry about how SDN can be used to configure a converged LAN/SAN fabric. Can you talk to this?

Question 4 @ 7:58 sec: Samrat, there are multiple approaches for SDN controllers, be it in a hypervisor, an appliance, part of a cloud stack, etc. How do you see the role of the controller evolving over time?

Question 5 @ 9:17 sec: Rakesh, How do you see SDN evolving and how does programmable networking fit in?

Question 6 @ 10:52 sec: Samrat, same question. How do you see SDN evolving and how does programmable networking fit in?
