SRM 6.5 and Journal datastore?

Hi All,

I'm just getting familiar with SRM but not sure about what the journal is or does and the requirements.  We use Tintri storage and trying to decommission old EMC VNXs, so my question is do I need a traditional SAN to keep the SRM journal on?  Where does this even get configured in SRM?  We've just upgraded vsphere, esxi and SRM to 6.5.

Thanks,
