Re: Informix and RAID

Hi all, maybe Richard should stop driving alltogether ... ? ... and consider safer occupations, e.g. parachuting, rock-climbing or para-gliding ;) Anyhow, we are talking about risks here, and the term risk describes always a (very) relative concept. What is a high risk and therefore absolutely to be avoided for one individual can be easily acceptable to another individual. E.g. I know of 2 rock climbers (and with one of them I was myself in the mountains) who climbed in the highest difficulty levels - routes that I would asses for myself as "very dangerous". Both of them died in their teens or early twens - in car accidents near home - far from any mountain. While most of us would not accept the risks of rock climbing, possible death in a car accident is a widely accepted risk. The point of my somewhat philosophical aberration on this subject is, that maybe we've now discussed the RAID-x [with 0 < x <11] topic enough in this group and any further testimony may remain rather fruitless ... Another thing to consider is trusting only the statistics that you've forged yourself, a point of view that often can be changed only through an adverse life experience. And probably we should not force any die-hards to miss such an opportunity for a personality forming life experience ... ;-) Have a nice weekend, Martin -- Martin Fuerderer IBM Informix Development Munich, Germany Data Management Solutions owner-informix-list@iiug.org wrote on 17.12.2004 09:17:46: > "Spurgeon, John P" <john.p.spurgeon@intel.com> schrieb: > > >BTW, our group has supported as many as dozen critical OLTP database > >instances at a time for 20+ years, many of them running 24x7 for most of > >the year.
