Hi, we are using Informix 7.30 UC2 on a SCO box with 4 CPUs and a Mylex RAID 5 Controller with 6 harddisks (each 18 GB), 60 GB are reserved for Informix raw disks. How do the recommendations for performance tuning from Informix apply to a RAID system? Still 1 Cleaner per physical disk? The Mylex is a three-channel controller, we devided the disks into 3 system drives because of the Informix limits of 2 GB chunks (so we have 30 chunks, each 2 GB). Thanks for any hint into the best direction. Regards, Kai Shen Acer Computer Germany DBA I.T. Europe
