The VMware versus Cisco thing is overstated. It’s easy to conflate issues with all the excitement. The reality is that many customers have Cisco networks and will use VMware. They want Cisco & VMware to be partners. Customer first is corporate policy at both of these companies therefore Cisco & VMware will be partners. VMware has a software defined […]
VMware NSX got it’s official launch this week at VMworld. As a measure of how important VMware regards NSX, the first keynote on the first day is Martin Casado doing the official presentation.
My general view is the NSX is the real deal. I have been talking and writing about OpenFlow since May 2011 and many have complained that SDN isn’t important and I should focus on real network issues. Well, it should now be clear that SDN is a serious strategy issue and we might have been ahead of the market.
Bob Plankers is making the point that the purchasing proprietary corporate software for virtualization (such as VMware vCloud or Citrix Cloudstack) has its own value by avoiding having to build & test your own software: There is an attitude among some now that OpenStack is, or at least will be, our savior from vendor lock-in […]
Arista has announced the 7150S device. It’s low latency, 10 Gigabit and VXLAN terminating. What’s interesting to me is that Brocade and Arista are solving the same problem in different ways. Ivan has determined that Arista have decided to use the Intel chipset (I’m guessing the SM6000?) and then enable the tunnel termination features in the software.
I have to agree in part with Trevor Potts at The Register and object to VMware’s solution to the vCenter client platform problem. He got to ask VMware why they are using Flash instead of HTML5 and he runs down the list of options. Java – too much versioning, not much customer love (ie none, […]
TL:DR look like the first version of vSphere that has least amount of compromises for large corporates. In other words, it’s more usable than before. Importantly, VMware has delivered a lot of networking features in this release and it would be fair to say that they either “overdue” or “much anticipated”. Take your choice.
VMware testing shows dramatic performance improvements, especailly CPU reduction, when performing vMotion over RoCEE networks. Implications for future network designs are enormous.
Embrane uses concepts of IP Flows to scale virtual appliances. Embrane does this by managing IP flows and then directing to other appliances, in effect creating what I would call a two tier load balancing.
This is the Packet Pushers podcast recorded after the OpenFlow Symposium. We talk extensively about the possible value of OpenFlow, and the limited value of VXLAN. Note especially that VXLAN is not suitable for use as a Layer 2 Data Centre connection – it’s simply not suited to this task.
It’s obvious #VXLAN was conjured up by a cloudtard. Simple minds devise simple solutions without seeing the complex problems they missed. Here are five things that VXLAN tells us about the networking industry.
