We are always on Mainframe dasd never SAN. And as RS pointed out, the
mainframe does not use SAN. We live on a DMX where SAN and mainframe share
the box but not the disks.
Lizette,
R.S. claimed exactly contrary opinion. There are no non-SAN disks.
In other words ALL mainframe disks are SAN-attached.
OK, the answer was tricky and perverse a little bit. <g>
But - what is a definition of SAN?
Leaving history, Bus&Tag channels, etc. - we have FICON channels
connected through a switch (optional) to a DASD array.
Exactly the same equipment and physical topology is needed for FCP.
So, mainframe uses SAN, but usuallly not SCSI commands (with the
exception for FCP).
