#vBrownBag Episodes

Sorry for the post delay on this. But, here it is.. the 2nd part of the ICND series Study Guide. As with the 1st post, the core purpose behind these network exams is to help you better understand the concepts involved to achieve your VCP-NV (NSX). This exam (ICND2) is needed to complete the requirements

It’s been a long time since my last post, and as always, I appreciate the opportunity that the vBrownBag community offers me to publish here. I’ve been on the road with a growing list of project deadlines due to a new consultant role that I accepted, but I’m learning a lot so I hope to share all that new knowledge here.

In this occasion I will talk about what has often been cited as the main barrier to VXLAN adoption: the requirement of Multicast in the physical network and the resulting operational burden of deploying and managing such requirement.

Compute, Network and Storage are the 3 pillars of a data center. Storage had been my weakest point in terms of knowledge and experience.

Today I had a great chat with Brian Knudtson (@bknudtson) who is very knowledgeable in different aspects of the technology field and had opened my mind in the area of “Hyper-convergence”. In this post, I am stepping out of my comfort zone again and try to venture into this area and take a look at this emerging and expanding market. In VMworld 2014, VMware announced a new product EVO:RAIL which reinforce the idea that this “Hyperconvergence” market has huge potential in the coming years.

As mentioned in this article, there are many variables to take into consideration when deploying and configuring VMware Site Recovery Manager. When failing (or testing) your virtual machines from site to site, decisions must be made on what cluster will they start on, what priority will they be failed over, and what, if any, scripts will be executed after fail over has occurred. An equally important step is ensuring that the VMs can communicate on the correct network at the surviving site. VMware SRM has multiple ways of handling customization of a VM’s IP; one that is “automated” using IP Customization Rules and another that is completely manual, set configurations per VM.  Both are explained and shown below.

Note: Site Recovery Manager supports customization of the same guest operation systems which vSphere 5.5U2 supports. Check the document here for a support matrix.

So after an interesting North West VMUG event on 12th November, I’ve decided to write my own comments on the state of employment within IT. This is prompted by Neil Mills Talk at the above VMUG event, where he gave tips on super charging your CV, and the industry as he see’s it.

Most of my recruiting experience from the last year comes from a reseller/solutions provider point of view.

VMware’s Site Recovery Manager provides the ability to failover VMs in the event of a disaster or for planned migrations between datacenters. In my case, we’re using it for the former as we have two “main” datacenters, one located in Louisville and the other in downtown Chicago. Although we’ve tried to deploy applications with site redundancy in mind, some applications are simply reliant on a single site, whether by limitations of the software or by choice.

Decisions, decisions… Planning a VMware SRM deployment takes considerable thought as there are many choices and routes to accomplish the same tasks. For example, we could choose to utilize EMC’s RecoverPoint or VMware vSphere Replication to replicate the data to the opposite site. We could choose to create a dedicated “DR” VLAN or should we explore spanning Layer 2 across the datacenters using VXLAN or OTV. Should we purchase additional capacity at both sites or simply suspend “Tier 2/3″ VMs in the event of a failure to ensure resources are available?

As part of #vDM30in30 Eric Wright wrote a great article on reducing technical debt, which got me thinking quite a bit.  Mainly about automation, and the journey it takes to get there.  Here’s a couple more ideas on how to get you started on the journey if you haven’t already begun.

One of the most important concepts of The Goal is to increase throughput. Throughput is the rate at which the system generates money through sales. That is, when your company takes raw materials, processes them into a finished good, and sells it, the measured rate of that activity is your throughput. Severe emphasis on sales. Throughput is not the same as efficiency. Today, we will look at throughput vs. efficiency and how these concepts apply to IT.

Though we are focusing on throughput, we must state the descriptions of the two other measurements. Inventory is all the money that the system has invested in purchasing things which it intends to sell. Operational expense is all the money the system spends in order to turn inventory into throughput. I list the three definitions together because the definitions are precise and interconnected. Changing even a single word in one requires the other two be adjusted as well.

Good morning, afternoon, and evening to all the blog readers.

I was challenged by Eric Wright and the #vDM team to do two things. First was to write 30 blogs in 30 days. This seems to be working out, The second was to step up even further and be a guest blogger for #vBrownBag. We will see if I am asked to do it again.

 

So with the explanation out of the way, here we go.

The above introduction was more than just an explanation. In January of 2014, I decided it was time for me to start getting my name out there to maybe move up into a better career.  So I started a blog, updated my Linked-in, and started a Twitter account. The community I found on twitter was overwhelming.  One of the first people I followed on Twitter was Bryon Schaller.  He had just been accepted to participate in the #VirtualDesignMaster program.  So I started watching and following. I became more and more interested in the VCDX program and becoming a Virtual Architect.  From there I have gather 132 twitter followers.  I have followed 318 people/vendors.
