Re: Tape Libraries

The MDL can also replicate the data. One solution I am known of starts the replication at tape close. There are other options.
For example. If the MAS/MDL uses a DS6800 to store the Tape volumes, then the DS6800 can PPRC (in real-time of course) to a second DS6800. This is valid for any kind of back-end disk subsystem that supports a peer to peer remote copy that you attach to the back-end of the MDL. In this case, the MAS/MDL is not aware of the replication.

From EMC literature:
Using EMC replication capabilities, tape volumes stored on Celerra by the
Mainframe Data Library can be automatically duplicated to a remote location.

I don't know if this is 'immediate' or via a data trickle. We haven't
implemented MDL at remote DR site, but understand it will be funded
at some point.
