Hi Niall,
We have been doing this for a number of years using EMC snapview. We produce
clones for development.
We have found it useful to have multiple source luns to clone from, as not all
developers want their source lun updated at the same time.
It seems to work really well, is scriptable and saves a bundle of storage. I
would not describe these clone databases as performant, but for our purposes
they do not need to be.
regards,
jason.
