Virtualisation and testing

Once upon a time, if you said to someone “do you have a test environment?” there was at least a 70 to 80% chance that the answer would be one of the following:

Only some very old systems that we decommissioned from production years ago
No, management say it’s too expensive

I’d like to suggest that these days, [...]

What’s missing with thin provisioning?

I’m stepping out of my normal NetWorker zone here to briefly discuss what I think is a fundamental flaw with the current state of thin provisioning.

The notion of thin provisioning has effectively been around for ages, since it’s effectively from the mainframe age, but we started to see it come back into focus a while [...]

First thoughts – VMware Fusion 3 vs Parallels Desktop v5

As an employee of an EMC partner, I periodically get access to nifty demos as VMs. Unfortunately these are usually heavily geared towards running within a VMware hosted environment, and rarely if ever port across to Parallels.

While this wasn’t previously an issue having an ESX server in my lab, I’ve slowly become less tolerant of [...]

Nybbles

If you thought in the storage blogosphere that this week had seen the second coming, you’d be right. Well, the second coming of Drobo, that is. With new connectivity options and capacity for more drives, Drobo has had so many reviews this week I’ve struggled to find non-Drobo things to read at times. (That being [...]

Aside – Parallels Desktop 5 for Mac OS X

I’ve been using Parallels Desktop for the Mac for several years now – in fact, when I originally started using it, VMware were only talking about doing a desktop virtualisation product for the Mac.

That’s partly why I stay loyal to Parallels – they supported the platform sooner. The other reason is that after years of [...]

Virtualisation as an exercise in MTBF

When IT people discuss Mean Time Between Failure (MTBF), the most common focus is on disk drives. We all know the basics for instance – the more drives you put in an array, the lower the cumulative MTBF, etc.

What impact does virtualisation have on MTBF though? Are there any published studies? I suspect not yet.

I’ll [...]

Great VMware coverage

My colleague Brian Norris has been continuing his VMware coverage over at Going Virtual.

Recently he’s been doing a lot of work on securing ESX, integrating ESX into Active Directory, and experimenting with vSphere v4. If you’re interested in VMware and are looking for some tips and coverage from an expert, I’d suggest you keep an [...]

Things not to virtualise: backup servers and storage nodes

Introduction

When it comes to servers, I love virtualisation. No, not to the point where I’d want to marry virtualisation, but it is something I’m particularly keen about. I even use it at home – I’ve gone from 3 servers, one for databases, one as a fileserver, and one as an internet gateway down to one, [...]
