'Always on' is becoming the status quo. Downtime is increasingly expensive and unacceptable. IBM z15 solutions are designed to deliver 99.99999%* availability. Wow! No more than 3 seconds of down time per year. But how? Let’s look at a roadmap for achieving seven nines of availability – starting with a single CEC all the way up to multi-everything. As a sysplex techie, I’ll certainly show how sysplex plays in the mix. In the end, you’ll leave with both high level concepts and practical suggestions that will enable you to improve availability for your installation - no matter where your business sits on the availability journey!
