Musing: VMware Pays More for AirWatch for VDI than Nicira for SDN

etm-musing-logo-300-300-opt

As a network professional, it can be difficult to maintain a sense of perspective in relation to other areas of IT. Certainly, networking is the foundation on which all other services depend but it isn’t all that important to customers overall. VMware announced that it was buying AirWatch to boost it’s VDI capability in mobile […]

Visual Guide to LAG Thinking for Server Admins

When working with Server and VMware people, there is a fair amount of misunderstanding of what is happening in the network. The best technical explanation for what is happening in LAG is, of course described at Ivan Pepelnjak’s IPSpace Blog – vSphere Does Not Need LAG Bandaids – The Network Does while Chris Wahl talks about the server side for VMware but I wanted to add something to the debate.

Musing On the VMware “versus” Cisco Thing

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 […]

Uncollected Thoughts on VMware NSX

NSX Standalone Graphic

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.

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 VTEP VXLAN 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.

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.
