Welcome to the future. DASD has evolved to Storage Arrays that pretend to be 3390s. The Storage Arrays can contain spinning disk or EFD/Flash Drives
Tape can either be virtual or physical depending on your environment. Try searching for Storage Array. EMC VMAX, IBM TS7700 IBM DS8K and so forth. This is a wide and vast land with lots of OEM products that can also do this type of work. There are RED Books that you might want to look for. ABCs of SYSTEM PROGRAMMING, THE NEW MAINFRAME Lizette -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Quasar Chunawala Sent: Thursday, August 22, 2013 7:01 PM To: [email protected] Subject: DASD, Tape and other peripherals attached to a Mainframe 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!
