VXLAN is an exciting new networking protocol that can lead to some interesting applications. But how can you get VXLAN in your network without breaking the budget? Tom Hollingsworth takes a look at Mellanox Spectrum and how it can get you what you need without a second mortgage.
Ryan Booth of Moving Ones & Zeros comments: Smaller shops might be fine with giving up a few links, but extending a L2 domain is asking for trouble. Larger shops need every link they can get and demand the flexibility to move a VM anywhere. So we are being forced down a road of L2 […]
Carl Niger of Come Route With Me! comments: I wrote a bit about basic 1000v information a bit ago with a promise to write about some misadventures with VxLAN on the platform. Here I go! As mentioned in the previous post, the 1000v essentials licensing (freemium) is all that is required to get some VxLAN […]
Carl Niger of Come Route With Me! comments: I’ve been failing miserably at getting some posts written. Working with VxLAN and leaf/spine design a lot lately, and also trying to get 1kv working on KVM (serious dearth of documentation there) though, so hopefully there will be some cool new stuff soon. In the mean time, […]
Greg Ferro of Ethereal Mind writes: Overlay networking has been around for a year or so now and the ideas behind it are well established. It was about 3/4 weeks ago while researching VTEP functionality in Dell and Arista switches that I realised I could build manually configured tunnels with VXLAN and get the same […]
Ivan Pepelnjak from ipSpace.net comments: Microseconds after VXLAN was launched at VMworld 2011, someone started promoting it as a data center extension solution. Even though layer-2 DCI doesn’t make much sense (even to server people) and VXLAN is really not a DCI solution, the lure of misusing a technology was irresistible. Read more at: Temper […]
Ivan Pepelnjak comments at ipSpace.net: VXLAN, one of the first MAC-over-IP (overlay) virtual networking solutions is definitely a major improvement over traditional VLAN-based virtual networking technologies … but not without its own scalability limitations.

Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.
What elements remain unresolved to make FCoE truly world-class? What should the vendors be prioritizing?
Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.
