Volume optimization in an FC or iSCSI environment
You can optimize your volume usage in a FC and Internet Small Computer System Interface (iSCSI) environment by having host-specific Logical Units Numbers (LUNs) on the same volume.
In addition to this, you can also optimize your volumes by performing a few other tasks:
When multiple hosts share the same storage system, each host should have its own dedicated storage system volume to hold all the LUNs connected to that host.
When multiple LUNs exist on a storage system volume, it is best for the dedicated volume, on which the LUNs reside to contain only the LUNs for a single host. It must not contain any other files or directories.
