The Lightning 9900 V Series provides “virtual” Fibre Channel ports that are logically managed by intelligent Fibre Channel controller cards. Each physical Fibre Channel port may have multiple Host Storage Domains. A Host Storage Domain supports a “logical” Fibre Channel port (Fig. 7) each with its own set of LUNs. Hosts are matched to their assigned HSD based on a unique World Wide Names (WWNs) identifier. LUN security provided by Hitachi SANtinel™ software fences access to LUNs based upon host WWNs. Under this innovative software structure, each of multiple host systems may have its own unique LUN 0, from which it can boot, within its own Host Storage Domain.
