High Availability (HA) in ConfigMgr 2007

hho@pqr.nl — Tue, 16 Aug 2011 23:00:00 +0100

In ConfigMgr 2007 it is difficult to have a true High Availability (HA) solution. This because it isn't supported yet in ConfigMgr 2007; we must wait for ConfigMgr 2012 for that. There are possibilities however with dividing roles on multiple servers, or install it on a Virtual Machine. Then there will be possibilities with VMware ESX (VMotion) or Microsoft Hyper-V (Live Migration) to create a HA environment. ConfigMgr 2007 is not HA then, but the platform on which it's running is.

Scheduled monitoring of ESXi hosts

hbr@pqr.nl — Tue, 16 Aug 2011 23:00:00 +0100

In my post on sizing up the storage for block size usage, I wrote a script to get the data into a manageable form. This script runs fine from the command line but you probably want to have some sort of trend to analyze.

In that case, you want to go and schedule running the script. Now the ESX host has a scheduler called ‘cron’. In full versions you would simply add a script to /etc/cron.hourly and it would pick it up on the next run. In ESXi this is slightly different. To [...]

It's SAMPLE time with vscsiStats

hbr@pqr.nl — Tue, 08 Feb 2011 23:00:00 +0100

vscsiStats is a new VMware tool that helps give insight in disk IOs and latency and stuff like that. It’s a very useful tool but it dumps data in histograms. Using these in Excel is quite a pain because Excel knows histograms (with add-ins) but only one at a time. If you want a graph a whole LUN or other lower level part of the storage over time, you need to reformat the data. And luckily, ESX, like most Linux versions nowadays, comes with a python interpreter. Now I know a lot of diffe [...]

Import a VM into Lab Manager using Orchestrator (part 2)

hbr@pqr.nl — Tue, 09 Nov 2010 23:00:00 +0100

This is part 2 of a quick guide to importing a VM into Lab Manager using Orchestrator. In case you missed it, part 1 is available on http://virtuall.eu/blog/import-a-vm-in-lab-manager-using-orchestrator.

Lab Manager import preparation

In the previous blog we selected a VM and exported it to a fileshare. Unfortunately, for Lab Manager to understand this VM export, we need to change it a little. First, we need 2 xml files; a configuration.xml with this content:

Import a VM in Lab Manager using Orchestrator

hbr@pqr.nl — Tue, 02 Nov 2010 23:00:00 +0100

There are a lot of things you can automate in a virtual infrastructure. One of the tools that can help automate the more complex workflows is Orchestrator. It’s free when you have a vCenter and it’s very powerful.

Another great tool is Lab Manager. It’s designed for Test and Dev environments but it can also help to improve uptime of your datacenter by regulating changes in your production environment.

This is a Proof of Concept combining the two tools as they overlap o [...]

Script bits (update 4)

hbr@pqr.nl — Mon, 31 May 2010 23:00:00 +0100

This post is a quick gathering of a few small scripts I wrote with my IT-life's motto: "Never do anything twice"

None of them are very special but each of them is a result of a short moment of frustration and a few minutes of gvim typing (yes, I use 'vi' on windows too).

so far this article contains:

Add wallpapers from a lot of subdirs to a Windows 7 Theme Change everybody's manager in Active Directory Execute one command on all you [...]

ESX Deployment Appliance (EDA) Quick startup and troubleshooting guide

hbr@pqr.nl — Mon, 14 Sep 2009 23:00:00 +0100

The current version is 0.95. Download the main appliance from Download v0.95. Don't forget to use the alternate OVF file at the same download location if you need to import the VM into previous Virtual Infrastructure versions. This guide is written for previous versions but except for some first time wizards, it still applies to the newest release.

If you have anything to say about this appliance, don't hesitate and go to the VMTN forum for this appliance.
