Recently I have been thinking a lot about the basic process we go through when designing an infrastructure solution, the choices we make, and why we make them.
These processes may be carefully structured within well-formed and trusted architectural frameworks, or they may be the sort of inherent thoughts that whiz through your mind when [...]
Too frequently I hear the expression n+1 as a model for ESX clusters to provide High Availability. If you EVER expect to patch ESX servers without VM downtime then you need at least(†) n+2. When running your clusters to only n+1, you can never safely put one of your hosts in Maintenance Mode; not if High Availability is important [...]
Following on from my last post about kickstart scripts which looked at partitioning, this one concentrates on user account provisioning. There are lots of useful guides online about how to configure user accounts, however none that fitted all my requirements. So nothing below is groundbreakingly new, but it does demonstrate a complete working [...]
The default GUI install of ESX4 makes the /tmp partition 1GB and even then it is only categorized as optional. I’ve been asked several times why you’d want to make /tmp any bigger. If it fills up you just clear it out, right?
Well here’s a good reason. It seems that VUM (vCenter Update Manager) [...]
Here’s my list of VMware exam study resources. I realize that a lot of fellow bloggers have created similar lists, and I always try avoid what the rest of the madding crowd are doing, however in this case I’m happy to follow along. Firstly I need the list for myself. Yep, I haven’t actually sat [...]
Here is an update to my vSphere 4 reference card
I’ve made lots corrections and updates, many of which came from VMware publishing a new version of their Configuration Maximums document last month. I’d also like to make a special mention to the follow people who took the time to get [...]
Dudley passed me the latest version of the Firewall diagram. Go and grab it:
Here’s what’s new since the last download:
What’s new in v3:
Now synchronized with “VMware Network Ports Compendium v3″
What’s new in v213:
Change port range in VUM to 9000-9100 (and [...]
I’ve updated my vSphere4 notes. Grab them over here.
The main documentation set is now complete, and I’ve just got a few more to cover. Those in red are still to be done. On with the vSphere4 reference card…
Main Documentation Set (ESX not ESXi)
Introduction to VMware vSphere [...]
You’ll be glad to hear that I’m in the process of collating information for a new vSphere4 reference card. I hope to have the first draft out in a only few weeks.
As part of that effort, I’ve been trawling through all the new GA ESX4 documentation. I thought I’d offer my condensed notes up [...]
Whilst reviewing the new ESX4 Web Admin Guide last night, I came across a “new feature”. If you log into a ESX4 WebAccess session and add a new disk to a VM, you have the option to change the “Write caching” policy from the GUI. This option isn’t available from the vClient view.
After [...]
