I've been blogging over the past couple of weeks under the theme "Everything you think you know about clustering is wrong". It's sort of a tongue-in-cheek theme, but the misconceptions I was trying to dispel are real and held by enough people that I felt they were worth addressing. But now I want to shift gears a little bit.
In my last post, I mentioned how a lot of people can't seem to break out of the late-1990s mindset of 2-node active/passive failover HA:
While large clusters meant we no longer needed two nodes for every critical application, many people's mindsets were still stuck in 1997 and they continued to view HA clustering in a 2-node, active/passive context.
To be sure, that's definitely not the case with all of our customers, especially...
