Brocade Vyatta 5400 Virtual Router on vSphere

Introduction As Software Defined Networking grows in popularity and adoption networking companies are branching out from their traditional hardware platforms by offering virtual appliances and software based management tools to address this market. Brocade’s Q4 2012 acquisition of Vyatta allowed the storage networking vendor to come to market with their virtual appliance for IP services, the Vyatta 5400 vRouter. Vyatta’s history of creating solutions for routing and IP security services… Read More »

Networking with Virtual Cisco Routers on vSphere

Introduction When I build an environment in my lab I need it to be as close to production reality as it can be.  When I am at a client I need to be certain of how the compute, network, and storage resources are going to interact. From a compute perspective this is easy to simulate in a  lab environment. vSphere was made to do it. Things get trickier when trying to… Read More »

Docker on Windows with VMware Workstation and Vagrant

Introduction My company laptop is an HP Elitebook that runs Windows 7. I’ve requested a Macbook Pro in the past, but to no avail so I am forced for various reasons to spend the majority of my time living in a Windows world. This is usually not an issue and for the most part I think that Win7 is a fine business desktop. However it is in a issue in… Read More »

Install and Configure RabbitMQ Integration with vCloud Director

Defining Automation With Messaging In today’s world of distributed systems and cloud computing  independent compute nodes need to communicate with each other to enable end to end services. The process of enabling this communication is the core of automation. In the client-server model servers generally communicated with each other via messaging services like Microsoft’s Distributed Transaction Coordinator. As systems became more complex and optimized for speed the Advanced Message Queuing… Read More »

Defining The Machine Lifecycle as a Service

A Service is a powerful thing. It is the basis for all automation and orchestration. One of the hardest things I have to do in my job is define “as a Service” to people. “X as a Service” has become a huge buzzword, yet few folks actually understand what it means. The first step in automating any task is to document it as a series of one or more services. ITIL… Read More »

Useful Linux Commands for ESXi

ESX has long had its roots in the Linux OS. Depending on the version, and who you ask, ESXi contains traces of RHEL, SLES, CentOS 3.9 and CentOS 5.3. With every release ESXi takes another step away from “standard” Linux, but the heart is still based on ld and glibc. This means Linux commands core to a standard bash shell still work. vSphere 5.x also ships with the “Swiss army… Read More »

Rapidly Deploy Hadoop on vSphere: Part 2 – Distros

In Rapidly Deploy Hadoop on vSphere: Part 1 – Basics I discussed how to setup vSphere Big Data Extensions and deploy a Hadoop cluster using the built in Apache Hadoop 1.2.1 distribution. While this will get a basic cluster up quickly you don’t get any of the other features that come with commercial distributions. VMware has addressed this by allowing you to add other distros to vBDE manually. Once they have… Read More »

Rapidly Deploy Hadoop on vSphere: Part 1- Basics

During his remarks in the General Session at PEX 2014 VMware CTO Ben Fathi said that Hadoop clusters were part of the 20% of the enterprise data center not being virtualized. This makes a lot of sense in a use case where you have a very large data set that is either static or slowly growing. However due the adoption of ideas like “The Internet of Things”, more companies are… Read More »

EMC Virtual Lab: VIPR, VNX, and Isilon on a Soapbox

We live in strange times. People have compared nested ESXi hosts to the movie “Inception”, but that is the tip of the iceberg. In this era of the Software Defined Data Center Enterprise you can define software that defines software that defines software that somewhere eventually defines hardware. I’m neither kidding or being extreme. Nowhere can I find a better example of this than my EMC lab that has no EMC… Read More »

Visualizing vscsiStats with RStudio

  After yesterday’s post we have gathered valuable data about VM drive activity through with the vscsiStats tool. It is time to put that data to use. The CSV file that was generated is broken down into 16 different metrics for each drive collected and reported as a Histogram. While the numbers themselves are helpful, they have a much larger impact when they are visualized. This can be easily done… Read More »
