Currently in Storage Manager you have a root group and under that you can create bussiness groups under that you can create sub groups, What I would like to see in future releases is that once I have create my bussiness groups and sub groups and assigned my hosts to a specific bussiness group that the host will not be visible to any other bussiness group I have created.
Once I have assined the Host to that bussiness group I would like to see that I can then assign that host to any of the sub groups I have created.
This would refer to all Storage Arrays, Server's and their Storage, Esx Hosts and Clusters, and not forgetting Backup
