Thanks for the tip, JAM. It sounds like good news!

this interface would need to implement the NTFS file system architecture in
its own code. The same with ext3, or ext4, or btrfs, or ??? with Linux. Or
that the LUN would not have a file system on it at all. It would just be a
"raw" device to z/OS and ??? on the SAN side and they would need to
implement their own file system time code. ​


 * We share DASD in mainframe land all the time.
 * We share "minidisks" in VM land all the time.
 * It's been proven that virtual Linux (any platform, not just z)
   can share disks (LV, disk "images", or physical devices).
 * Evidence suggests that disk sharing can be extended to other systems.
   (Maybe even Windoze, but certainly Unix systems can cope: AIX,
   Solaris, HP-UX, the BSDs.)


SAN is to the rest of the world with FICON DASD is to the mainframe.
Wow ... what a concept!
Let the sharing begin.

 * EXT2 can be shared R/O among systems (virtual, real).
 * EXT3, 4, and BTRFS are journalling and tend to attempt replay even
   when mounted R/O.
   (Force the underlying volume R/O and ignore the replay errors.)
 * dunno NTFS all that well, but isn't it journalling? good luck
 * ISO9660 can be shared among systems (virtual, real, even unlike op
   sys!). The FS is R/O by nature.
 * A LUN with no FS at all is "just a file" to any Unix. Read it. Write
   it!


R/O sharing is safe.

Single R/W with multiple R/O can be done with care. (Think LUN switching 
or minidisk flipping.)


R/W filesystems can be shared when some form of media locking is 
available. To date (as far as I know) such locking mechanisms have been 
out-of-band. (See OCFS2 and GFS2 for examples. Please correct me if I'm 
wrong, if either of them can do in-band locking.)


If I seem a little excited about the idea, well ... you betcha!

See XIPFS mod to EXT2FS for memory based sharable block storage. (But 
try that with NAND flash? Good luck with that.) And y'all thought 
hipersockets were fast.

Interesting.  Some of the details are a little odd, shall we say:
"z/OS FBA devices are implemented as a new device or control unit type in the 
Unit Record (UR) class of devices."  Wow.  A new unit record device.  The first

And

was I in a coma when this was discussed: z/OS FBA Services

[John McKown]

Apparently for the DS8700 and above with an option called zDDB.

http://www.ibm.com/support/knowledgecenter/api/content/SSLTBW_2.2.0/com.ibm.zos.v2r2.ieaa800/fbaasm.htm?locale=en



z/OS FBA services

z/OS FBA services provides the ability to manage and perform I/O on z/OS
systems, exploiting the z/OS Distributed Data Backup (zDDB) multi-platform
access feature on DS8700 and subsequent model type devices. The new
application programming interface (API) provides functions to allocate,
read from, write to and deallocate z/OS FBA devices.

z/OS FBA devices are defined using the Hardware Configuration Dialog (HCD)
or Hardware Configuration Manager (HCM). z/OS FBA devices must be online in
order to be used by z/OS FBA Services.

z/OS FBA devices can be used in many ways. For example, z/OS FBA devices
can be used as a data transfer device between a z/OS system and a
distributed system. It can also be used as a shared data device between
z/OS and other systems. The z/OS FBA service encapsulates the management of
z/OS FBA devices and provides capability for I/O channel program creation
and execution from z/OS systems.
