(Am I missing whimsical intent?) What programs, utilities, facilities would you expect to exploit such a filesystem? Doesn't zFS already emulate a raw FBA storage device? Embed a z/OS native filesystem there. I was actually thinking of beginning to wean z/OS off ECKD DASD. As things stand today, all storage is native FBA, but for z/OS the storage subsystem has to emulate the 3390 (or even 3380) architecture. Then the linear VSAM dataset container file for a zFS filesystem has to emulate FBA back again. My idea is to eliminate the layers of emulation. Things that can already exploit zFS would have no trouble exploiting this. Also, programs that use QSAM or BSAM can in many cases run just fine using Unix files instead of MVS datasets. IBM should make that even easier, and provide more ways for other things to exploit Unix directories and files, instead of depending on a 60 year old storage architecture that seems to clearly have been a mistake from the start. -- Curtis Pew, Mainframe Specialist The University of Texas at Austin | ET Campus Solutions ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
