Reliability of a system is usually expressed as a percentage of uptime. A system that has an uptime of at least 99,9% should typically not exceed an unplanned downtime of roughly 8 hours and 45 minutes each year. ‘Five nines’ or 99,999% of availability is often used in IT: this equates to roughly 5 minutes of downtime on a yearly basis. For Infinidat this wasn’t good enough, so they built the Infinibox with a reliability of 99,99999%. That’s only 3.2 seconds of downtime per year. Yikes!
Woohoo: I will be attending Storage Field Day 8! The 8th edition is held from October 20th till the 23rd in the same location as always: Silicon Valley, CA, (USA, Earth, etc). I’m very excited to return: Storage Field Day 7 was a big success and this time around it shouldn’t be any different. The line-up of presenting companies is impressive: I’ve met some of them at previous Storage Field Days and there’s a couple of new names that I’ve been really looking forward to meet.
