Availability is about BEING available

Another excellent resource focusing on the practices of Availability and what this means is The Availability Digest by Dr. Bill Highleyman.

His site focuses on the processes and practices, not a platform. 

Although many Tandem/NonStop users know Bill as the guy who wrote the book, literally, on Performance Analysis and Tuning for OLTP systems, his digest gives food for thought (no pun here) about the process of establishing and maintaining availability as well as some pretty interesting "never again" horror stories.

I invite you to take a look at http://availabilitydigest.com/ and sign up for his digest if you see something that sparks your interest there.

I've provided a link from this page, on the right side control bar, to this and other sites of interest.
