VXLAN Deep Dive, Part 2: Looking at the Options

September 30, 2011 at 9:15 am PST

Hey folks--this is the second of three posts looking a little more closely at VXLAN.  If you missed the first post, you can find it here.  In this installment we are going to look at the some of the other options out there.  Two of the most common questions we see are  ”why do I need yet another protocol?” and “can I now get rid of X?”  This should help you answer these questions.So, let’s dig in… Read More »

Digging Deeper into VXLAN, Part 1

September 29, 2011 at 2:50 pm PST

Yes, I am still talking about VXLAN, rather you folks are still talking about VXLAN, so I thought its worthwhile digging deeper into the topic since there is so much interest out there.  There also still seem to be a fair number of misconceptions around VXLAN, so let’s see what we can do to clear things up.

This time around, I have some partners in crime for the discussion:

Larry Kreeger is currently a Principal Engineer at Cisco Systems’ SAVTG working on Nexus 1000V architecture. Larry has a wide ranging background in networking accumulated from over 25 years of experience in developing networking products.  His recent focus is data center networking, especially as it relates to data center virtualization.

Ajit Sanzgiri has worked on various networking technologies at Cisco and other bay area networking companies over the last 16 years. His interests include hardware based switching and routing solutions, Ethernet and wireless LANs and virtual networking. Currently he works on the Nexus1000v and related network virtualization products.

So, Larry and Ajit have put together this VXLAN primer--its fairly dense stuff, so we are breaking this into three posts.  In this initial post, we’ll cover the basics--why VXLANs and what is VXLAN.  I know I’ve covered this to some degree already, but Larry and Ajit are going to dig a little deeper, which will hopefully help clarify the lingering questions and misconceptions.  In the next post, we’ll discuss how VXLAN compares with the other tools in your networking arsenal, and, in the final post, we’ll cover more of the common questions we are seeing.

Oracle VM Consolidation and Path to the Cloud on Cisco UCS

September 23, 2011 at 10:08 am PST

I recently wrote about our participation to Oracle OpenWorld 2011, highlighting John Chambers key note speech and the importance of Cisco and Oracle partnership

Yesterday I talked with one of the Cisco experts on Oracle , John McAbel – John will have a speaking session ((Session #9208)) with Oracle VM Product Management Director Ronen Kofman , and was kind enough to explain in front of the camera what it is about

Here is the extract of the session

Oracle VM provides users with an array of new capabilities to help manage and consolidate workloads as a first step to a cloud implementation. The underlying hardware must be architected to combine compute, network, and storage elements balanced correctly to help ensure maximum performance.

The Network is Changing – Is Your Network Cloud-Ready?

Today’s IT organizations face a broad set of challenges today.

  • How to deal with the proliferation of end-user devices? (smartphones, tablets, etc.)
  • How to deal with the proliferation of virtualization and it’s new operational model?
  • How to adapt to requirement for new application traffic patterns (east-west, VM mobility)?
  • How to manage the edges of their networks as work/life locations blur?
  • When do they decide to deliver a business need via internal resources vs. external resources?
  • With all this technology change happening so rapidly, how do they align their teams?
