Difference between the V3 storage host and mapping


A host is the virtual host created on the ISM interface and can be regarded as a logical application server. By configuring an initiator, you can establish connections between the virtual host and physical application server.
Mapping is the relationship established between a host and a created LUN for an application server to use the storage space provided by a storage device.
