8.5Multi-Host Access Control: LUN Filtering

RAID-based mapping provides access control over a Storage Area Network where:

1.Servers may share common storage;

2.File integrity becomes a problem and access contentions might occur;

3.File access must be coordinated among multiple servers.

Storage Pool

RAID-based mapping provides the centralized management for host-storage access. It is derived from the concept that storage can be divided into manageable pieces by mapping storage units to different Logical Unit Numbers (LUNs). The storage can then be managed in the context of a LUN map. We then append filtering mask(s) to the LUNs making specific storage unit accessible or inaccessible to one or multiple host adapters (HBAs).
