Not all Orchestration tools are created equal

I’ve been doing a lot of work with the Release Candidate of System Center Orchestrator, so it’s always interesting to see what other orchestration products are capable of.  I recently read a blog post on Creating Workflow Loops in vCenter Orchestrator and I was struck by just how complicated it is to do relatively simple…

Disingenuous Cost Comparisons

I was inspired by Eric Gray’s recent post “Disingenuous cost comparisons” which purports to show all the ways that VMware costs less than Microsoft.  I thought I’d take Eric’s advice and see for myself by trying the VMware cost comparison calculator and see exactly how VMware are trying to reduce the high cost of their…

Controlling HP ILO with Opalis

Back to my long neglected blog… Inspired by Adam’s post about building his own Opalis integration pack I thought I’d give it a go myself.  I’ve seen the sessions at MMS, but never actually sat down to do this.  I thought I’d start with a scenario that I was looking at for my demo environment,…

Hotfixes for DPM Protected Hyper-V Guests

One of the things that isn’t made 100% clear in the DPM documentation is what you need to do for Hyper-V VM’s that you are protecting at the Hyper-V host layer.  The “Protected Computer Software Requirements” document on Technet tells you that you need to apply certain hotfixes to the Hyper-V host, and you could…

server cluster patching with opalis – part 2

In my last post on this subject I set up the cluster patching framework in Opalis.  In this post I’m going to modify the policy initiation phase to use PowerShell & some text manipulation to make it more dynamic. I’d set this up originally to simply read the cluster nodes from a text file.  There…

Server Cluster patching with Opalis – Part 1

I’m using this post to document my experiments with Opalis.  One of the things I’ve been thinking about is using Opalis to orchestrate complicated patching scenarios that have traditionally been difficult to do with tools like System Center Configuration Manager alone (or at least would have involved lots of scripting).  For example patching a cluster…

Exercising live migration

One of the scenarios that we had running at TechEd NZ was a continuous live migration between two hosts which I had set up using Virtual Machine Manager & the Powershell components.  Someone asked for it internally, and I thought I’d post it here in case anyone else would find it useful. This is useful…

Application Virtualisation – Agent or Agentless Part II?

In my previous post I talked about some of the advantages of using agent based technology to deliver virtual applications.  There were a couple of things that I forgot to include when I wrote that post.  So continuing on from that list, here are the extras: 5. Inventory If I’ve got my application content separated…

Application Virtualisation – Agent or Agentless?

One of the things I sometimes hear from my customers when we’re talking about Application Virtualisation is “why do you need an agent for virtualising applications, especially when some of your competitors don’t?”.  My answer to them is “what do you think an agentless solution does except introduce management overhead?”.  Sure it looks attractive in…

Save money managing your virtual hosts

As I said in my post below, I read a lot of blogs.  I’ve been meaning to write a response to a post I read on Vcritical.com for a while, and haven’t got around to it.  Vcritical is written by Eric Gray who is a VMware employee, so clearly he has a biased view, much…
