A colleague and I were talking as we feel the powers to be are looking at "options other than the mainframe". The talk went to dollars and cents I stated the price of a z box has dropped big(for our size shop) but the cost of purchasing dasd is still high along with maint.
His question was why can't mvs use scsi or san dasd, VSE and VM can.
We looked around the web could find nothing on it.
Thoughts??
thanks

My 2 cents worth: the "cheap DASD" doesn't live up to the reliability standards that IBM demands for z/OS. Stop and think, really hard, about the demands on z/OS DASD storage, as opposed to the "standards" you enjoy with your PC DASD. How many of your PC's stay up, with DASD spinning, on a 24/7 basis, for several years without problems?
