vCenter 5.1 SSO and Linked Mode …. recap …

I was talking to a customer yesterday about a storage solution and we strayed into a discussion about the vSphere Web Client, and compatibility with this, that, and the other (VUM and SRM to be specific). While we were at it, the subject of Single Sign-on (SSO) on vSphere 5.1 arose again. SSO is a difficult subject for many people still. Configuring it is tricky for some, and this is Read More …

Managing your Virtual DataCenter – 4 Key Strategies

While recently studying for VMware Advanced Professional Datacenter Design exam, I had the chance to study documents in the VCAP-DCD blueprint. Some of these documents provide insights into effective strategies to use before, during, and after deploying a Virtual Infrastructure. In terms of the “after” piece, one document caught my eye. It is the Glasshouse Whitepaper entitled “Four Keys to Managing a VMware environment”. You can find the document on the community Read More …

VMware Metro Storage Cluster Explained – Part 2: The Potential Solution

Recap In my last article, I discussed a typical dual-site scenario where storage replication is used to synchronously mirror a volume or LUN object between data centers. The goal is to mitigate the risk of Data Center failure. While it does that in some ways by creating multiple copies of data, the failover process is complex, depending on the scenario. Data can become corrupt, and systems can become isolated. There Read More …

VMware Metro Storage Cluster Explained – Part 1: The Challenge

First and foremost, vMSC stands for vSphere Metro Storage Cluster, that is, a vSphere HA/DRS cluster stretched over distance. After attending Duncan Epping & Lee Dilworths presentation at VMworld 2013 on vSphere Metro Storage Clusters (Session BCO4872), it got me thinking about writing this article. The use case for vMSC is pretty clear….to provide VM mobility and resilience across Data Centers. As a storage practitioner for 12 years, one of Read More …

VMware #VCDX Boot camp review 13/10/13

I was lucky enough to attend the VMware Certified Design Expert (VCDX) boot camp the Sunday before VMworld started at Hotel Melia, Barcelona. I would highly recommend it to anyone at advanced certification stage getting ready to launch into the VCDX process, and especially for those getting ready to defend their VCDX submissions. It’s open to Advanced Certified VMware practitioners (VCAP) only, in normal circumstances. I wanted to put my Read More …

My VCAP-DCD Experience at #VMworld–Take #1

I’m studying for VCAP-DCD (VMware Certified Advanced Professional – Datacenter Design) en route to hopefully achieving VCDX (VMware Certified Design Expert). The DCD exam is the final pre-requisite step for application and submission into the VCDX process. That is a personal goal of mine I plan to achieve next year. I did the DCD exam last Wednesday at VMworld in Barcelona, but I wasn’t actually planning on taking the exam Read More …

The Software Defined DataCenter: The Next 10 years

It is with excitement that all IT professionals peer into the future. Many of us have come from a past where we watched the UNIX operating system die a slow death. I worked with Solaris UNIX for many years and had customers who ran their mission critical development systems at 90% CPU on Solaris every day of the year. That was never a problem. The longer the uptime the more Read More …
