LUN Mapping
The RAID Controller has extensive support for LUN Mapping or SAN LUN
Mapping (SLAM). A LUN can be mapped to particular host HBA or to a particular
host HBA port. Up to 512 LUN mappings can be created, with a 2 TB per LUN
limitation. Online LUN addition and deletion is supported.
LUN Mapping allows multiple hosts and operating systems with exclusive access
to certain areas of the storage, without requiring host software for management.
Additionally, an internal LUN can be presented to a host system as a different
LUN number, simplifying multiple systems setup.
