Response: OpenStack Isn’t Our Savior From Lock-in or Support Costs — the Lone Sysadmin

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 [...]

◎ Comparing Arista and Brocade VXLAN VTEP Hardware Termination

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.

VMware’s vSphere Web Client Uses Flash ? That’s Pretty Weak.

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, [...]

Quick Look at Networking Features in vSphere 5.1

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.

Infiniband Over Ethernet Is Better Than Ethernet Says VMware

VMware testing shows dramatic performance improvements, especailly CPU reduction, when performing vMotion over RoCEE networks. Implications for future network designs are enormous.

Scaling Virtual Appliances With Embrane

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.

Show 71 – OpenFlow, SDN, Controllers, VXLAN & Wishing for Fishes

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.

Top Five Things About VXLAN – And Why It’s Full of Fail

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.

Outburst: VMware Networking Blog: vSphere 5 New Networking Features – Score D Minus – Must Improv

The VMware networking blog talks about the new networking features in vSphere 5. Well, talk would be overstating it. Mention, maybe. Post It Note, perhaps.

In fact, you could probably burp out the feature list on a single beer.

Soft Switching Fails at Scale

There is a significant camp of software developers who are developing software switching solutions for hypervisors. Which is nice, I guess. The use of software switching in the hypervisor has some good points but, in my view they are heavily outweighed by the bad. I present the use case, and show that software
