Welcome to vBlog, a personal record of my techy tinkerings and particular ponderings.

I tend to focus on VMware virtualisation, and the interaction/automation of it using PowerCLI (VMware's PowerShell Snapin), but anything that I happen to stumble across that seems like it might be of use at a later date, may well get recorded here.

I also maintain vWiki, which was a predecessor to this blog. Wiki's are great for quickly recording snippets of info, but tend not to look that great; Blog's are better looking things, but seem to require more effort so that the posts/articles are accessible in their own right. As a result I tend to update both interchangeably as available time, and depth of thought, permit.

If you happen to find anything of use, or in need of correction please leave a comment. Knowing that my ramblings are of some use is a great reward; and similarly I'd hate to waste anybody's time by feeding them duff info.

Zimbra Collaboration Server (ZCS) is a replacement for Microsoft Exchange, and comes in a nice free open source edition (aka FOSS); and also a premium Network edition (which includes bells and whistles such as support, mobile active-sync, on-line backups, a MS Outlook connector, etc).

The last time I touched MS Exchange it was version 5.5, so I’m in no position to compare the two. I’m not going to make out ZCS is perfect either, but similarly I’ve overheard sys admins voicing plenty of gripes regarding MS Exchange so I doubt ZCS is any worse.  ZCS is in fact very slick in places, and has a healthy support forum to assist in any problems you may have – there are organisations that use FOSS in production (and plenty that use the paid for version as well).
