Updated VMware support policy on MSCS

Erik Scholten — Wed, 18 May 2011 05:04:29 +0000

August 2010 I wrote an article on support for Exchange CCR clustering on VMware with iSCSI. VMware’s response then was very simple and straight forward. Exchange CCR clustering on VMware is not supported on iSCSI! When asked if VMware had plans to change this support issue in the future the response was promising. “The Exchange [...]

Review: Exchange Server 2010 training by TrainSignal

Alex Muetstege — Thu, 03 Mar 2011 11:57:49 +0000

Some time ago.. actually, a long time ago, we here at VMGuru.nl received a sample of a training DVD from TrainSignal. I promised to write a review on it, but I honestly didn’t come around to it due to all sorts of personal stuff. But the DVD box made it safely through the move from [...]

VMworld 2010 – The New Zimbra

Alex Muetstege — Thu, 14 Oct 2010 08:36:00 +0000

I’ve written about Zimbra before. Actually, we here at vmguru.nl use Zimbra for all our email and collaboration. So, today we were invited to join the Zimbra Breakfast Meeting at the Scandic Hotel in Copenhagen. Zimbra, for the ones who don’t know what it does, is a collaboration suite. It’s the open source exchange alternative. [...]

First experiences with Zimbra Collaboration Suite Appliance

A ‘bit’ of history Some of you might know me as a dedicated MS Exchange junkie. Ever since Microsoft launched version 5.0 of Exchange, I’ve been working with it and I must admit I never found a collaboration suite quite like it. I’ve had numerous discussions with Lotus Notes or Novell Groupwise folks but they [...]

Exchange CCR cluster on VMware with iSCSI

Erik Scholten — Fri, 06 Aug 2010 08:09:37 +0000

A few weeks ago I got an assignment to review a colleague’s infrastructure design based on VMware. The design was fine (because they used my design document as template ) but one thing triggered me. There was a special port group on one of the virtual switches names ‘MSCLUSTER’. No problem so far but I [...]

Virtual machine resources: Less is more!

Erik Scholten — Sat, 14 Nov 2009 11:38:41 +0000

This week a colleague called me with a VMware ESX problem. He’s doing a Exchange 2007 implementation and he configured a virtual machine which should function as the Mailbox server. He was complaining that the virtual machine took 13 to 15 minutes just to boot and he suspected a storage issue as they had been [...]

Virtualise Microsoft Exchange: Can you really?

Alex Muetstege — Tue, 21 Jul 2009 09:13:15 +0000

As Microsoft Exchange server is one of my area’s of expertise (or so they keep telling me ) I have had numerous discussions in the past whether you should virtualize Exchange or not. For ages Microsoft has claimed it cannot be done, performance would suffer severely, you would not receive support in a virtual environment [...]
