Hi experts, I work as an application programmer with a leading bank on CICS/Cobol for the past 4 years. Whilst I know, that data on the mainframe is stored on disks and tapes, I have never walked in to a data-center. At any mainframe data-center, what are different storage media used? Do they still use Tapes or 3390 DASD? I did do some research on the Internet, but found that the last 3390 was manufactured by IBM in 1993. What *storage media* is used to store petabytes of data and information? I also heard the term *DASD Arrays, * but I am not quite sure what they are.
I have yet another question. Can DASDs or tapes be virtualized? Thanks a tonne in advance!
