RAID-5 will kill of Informix. > > Koen I disagree! We are currently using RAID-5 with 60 GB hard disk from Sun and two of such servers are in production since June 3rd. There are many other servers which are not in production yet. So I will only address the two servers that are in production. We did not do fragmentation at all. Yet we have about 40 temps, two shifts. We are considering to add another shift. The performance monitoring tool we used (SymBEL) complaint a lot about CPU overload, slow internal hard disk. But it never complaint about the disk array. Chao
