Today I want to explain the basic components and the set-up of VMware NSX. In this case I’m referring to NSX for vSphere or NSX-V for short. I want to explain what components are involved, how you set them up for an initial deployment and what the requirements are.
At time of this writing the latest release is NSX 6.1.4. This version added support for vSphere 6, although you cannot use any vSphere 6 feature in this release, there is support for the platform itself only.
The first step is of course deploy your ESXi vSphere cluster with ESXi 5.5 or 6.0 with vCenter 5.5 or 6.0. I recommend using the vCenter Server Appliance (VCSA) instead of the Windows version. You will also need a Windows VM where the vSphere Update Manager is installed, this is not available as virtual appliance, only as Windows application. I also highly recommend installing an Active Directory server to manage all of your passwords. You will be installing a large amount of machines with all different usernames and possibly passwords. I recommend picking a very long and difficult one, as all VMware appliances seem to require Continue reading
Due to the high level of demand for the July Online CCDE bootcamp and the increase of individuals pursuing the CCDE, I have just added my next online class for the November 19th CCDE Practical exam. The class will not only include an overview of the technology concepts needed to pass the exam but also… Read More »

OpenContrail allows the user to specify a static route with a next-hop of an instance interface. The route is advertised within the virtual-network that the interface is associated with. This script can be used to manipulate the static routes configured on an interface.
I wrote it in order to setup a cluster in which overlay networks are used hierarchically. The bare-metal nodes are running OpenStack using OpenContrail as the neutron plugin; a set of OpenStack VMs are running a second overlay network using OpenContrail which kubernetes as the compute scheduler.
In order to provide external access for the kubernetes cluster, one of the kubernetes node VMs was configured as an OpenContrail software gateway.
This is easily achievable by editing /etc/contrail/contrail-vrouter-agent.conf to include the following snippet:
# Name of the routing_instance for which the gateway is being configured routing_instance=default-domain:default-project:Public:Public # Gateway interface name interface=vgw # Virtual network ip blocks for which gateway service is required. Each IP # block is represented as ip/prefix. Multiple IP blocks are represented by # separating each with a space ip_blocks=10.1.4.0/24
The vow interface can then be created via the following sequence of shell commands:
ip link add vgw type vhost ip Continue reading

Gartner refers to bimodal IT as “having two modes of IT, each designed to develop and deliver information- and technology-intensive services in its own way.”
If this week’s top articles are any indication, it’s certainly a topic that is at forefront everyone’s minds. We’ve especially been enjoying Kurt Marko’s series for Forbes. For some, bimodal is just another buzzword, but for others, it presents an entirely new way of approaching IT. It disrupts legacy IT, offering groundbreaking tactics for testing and rolling-out new technologies. No other area of IT needs this more than the network. As we’ve frequently discussed, storage and compute have evolved rapidly over the last decade, but networking has remained unchanged – despite huge shifts in the way we manage and move information. The articles below are certainly a good start to a lengthy discussion. Enjoy!
Forbes: Bimodal IT Doesn’t Mean Bipolar Organizations: The Path to IT Transformation
By Kurt Marko
Never underestimate a buzzword’s power to frame the discussion. As I recently discussed, the term bimodal IT has captured the imagination and polemical energy of technology commentators and like many IT discussions in the age of 140-character commentary, it often degenerates into polarized, all-or-nothing Continue reading

What features does the Netscaler platform have that make it unique? This isn’t just a bunch of fluffy marketing points. Rather, we opted to focus on some of the nuts and bolts of how NetScaler handles more interesting things like L7 packet manipulation, policy declaration, the use of promise theory, IPFIX extensions, that sort of thing.
