In R10 we supported VSAM, in R11 we added Extended Format sequential, and in R12 (the oldest release now in service) we added support for "almost everything else." There are still some outliers for system-level data sets (RACF DB, page data sets, NUCLEUS, etc.) but the vast majority of application data can now live happily on an EAV so long as it's read and written using system access methods. > > How far off is IBM from offering SSD technology in their disk arrays?

AFAIK, we would have had SSDs in our DS8800, if we had chosen for a section with high performance disks. It makes no difference how a disk dies if it dies, the box can handle a failed device.
