Dell PowerVault MD3260i - Manual (Page 157)

A host group is an optional topological element that you can define if you want to designate a collection of hosts that
share access to the same virtual disks. The host group is a logical entity. Define a host group only if you have two or
more hosts that share access to the same virtual disks.
