Some weeks ago I posted an article about some bad network performance when moving VMs to a new ESX host. Last week I got an e-mail which announced some updates and among it was the one promised to us by the engineer that helped us with our problem.

Alex Muetstege — Fri, 03 Sep 2010 12:40:15 +0000

Last sunday I took our Zimbra appliance into productionmode. About one week has passed and I must say, I still don’t regret the choice. Even with my 2 gigs of mail, Zimbra seems to be coping fine. I did notice a few things that could be improved though. But hey, which product is perfect? There’s [...]

First experiences with Zimbra Collaboration Suite Appliance

Alex Muetstege — Sun, 29 Aug 2010 18:31:40 +0000

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.

VMware Visio Stencil for vSphere 4 manuals

Edwin Weijdema — Fri, 27 Aug 2010 15:01:54 +0000

When VMware vSphere 4 went live I started collecting pictures from Sphere and the Virtual Infrastructure client, I combined them in a Microsoft Visio 2007 shape so I could track off them [...]

Our systems were not compromised. During this investigation, we also noticed several attempts that were made from within [...]
