Look, despite being told about a dozen million times, there’s still plenty of CFOs/IT Managers out there who have a “backup everything” policy, despite the fact that it’s easier to rebuild ESX than to build and recover, especially if you have a repeatable PXE-boot solution. However, the amount of times I’ve been out on site [...]

Scripting Queue Depth in a QLogic/EMC environment
First of all, apologies to anyone using Emulex, non-EMC SANs – this guide isn’t for you – I’ll try make a guide at some other stage. Also, at the end of this guide, I will publish a script that you can run in your Service Console to optimize your SAN performance. First, lets define some [...]
Cloning an ESX Server network configuration
I’ve had an email from Rick, who is trying to build a kickstart script based on his existing infrastructure. Currently, all he wants is a script to get the network settings from an ESX box in a format that kickstart can then farm out to new ESX installs. Lets do this. Method 1: The Hard [...]
Upgrading VI tools on all VMs without reboot
Usually, I don’t post powershell code, simply because there’s so much good stuff out there to write about – but this one caught my eye considering how useful this feature would be just before scheduled downtime. You’ll need the VI powershell toolkit for this: $cluster = “< >” # Enter the required cluster name $installerArgs [...]
Monitoring ESX Servers with Zenoss
We all would have seen the millions of blogs lighting up with the Zenoss 3 native VI3 monitoring announcement. Me, I wasn’t so interested – I’ve been using Zenoss for VMware monitoring for the best part of a year – the announcement ain’t that special. Really. I’m going to show you how to do it [...]

Linked Clones in ESX 3.5
Now, linked clones aren’t officially supported with ESX 3.5, except with Lab Manager. That doesn’t mean you can’t make it work. Let’s do it? 1. Create a new VM, install all the software you want on it, patch it, do anything you want. 2. Take 2 snapshots with the VM running, one after the other. [...]
Using a QLogic QLE220 HBA with ESX 3.5
Michael Mikheev at VM4RU has an excellent post about doing something I did a long time ago – and never documented. He’s got the method to enable QLogic’s cheapie HBA (QLE220) to work as an HBA in ESX. What I’m doing now, is no more than simple translation work from Andrey Vakhitov’s document hosted at [...]
A comparison of important features between Citrix XenServer 5, Microsoft Hyper-V 1.0 and ESXi 3.5u3
I think I’ve got about a dozen emails asking for a simple comparison table, and frankly I think the value of such things are nil because they cannot possibly cover everything. But, just to get it out there, here’s a table that I quickly threw together, based on the excellent work in this blog So [...]
VM Template best practices (Linux)
Update!!! – 2/06/2009 If your Linux server is a Ubuntu VM, enable the avoidance of persistent MAC bindings for VMware NICs, as per this post Update!!! – 12/11/2008 VMware doesn’t really provide best practices for VMs because it’s a matter of taste. So I’ll let you know how you can build templates that optimise your [...]
