Has anyone done performance testing that they can share to get numbers on relative performance of the same DASD, accessed under z/Linux, depending on whether it's presented as direct-attached 3390 or FCP SCSI?
Basically, my question is, all other things being equal, let's say I have a Shark and I want to get data off it into a Linux image: am I better off mounting that disk as SCSI or ECKD ? Adam
