We have a new HP9000 machine with 2 fast SCSI disks and 2 slower disks. We are using informix mirroring on them. Is there advantages or disadvantages if the mirror copies are both in the in the slow disks, or a mix of slow and fast disks ? I mean Disk A (slow) Disk B (slow) Disk C (fast) Disk D (fast) 1) dbspace 1 dbspace 1 dbspace 2 dbspace 2 2) dbspace 1 dbspace 2 dbspace 1 dbspace 2 Is option (1) or (2) more efficient ? ------------------------------------ Ti Lian Hwang DHL Int(s) Pte Ltd email : tilh@sin-co.sin-ro.DHL.COM ------------------------------------
