STORAGE CONTROL APPARATUS AND STORAGE SYSTEM COMPRISING MULTIPLE STORAGE CONTROL APPARATUSES |
摘要 |
A storage system has multiple disk controller (DKC) units that are coupled to one another in accordance with a coupling mode that satisfies the following (a1) through (a3): (a1) One DKC inside one DKC unit and one DKC inside another DKC unit are coupled via a second type of coupling medium that differs from the internal bus of the DKC and has a longer maximum communication distance than a first type of coupling medium, which is the same type of coupling medium as the internal bus of the DKC; (a2) the one DKC unit virtualizes a logical volume of the other DKC unit and provides this virtualized logical volume to host(s) coupled to the one DKC unit; and (a3) the other DKC unit virtualizes a logical volume of the DKC unit and provides this virtualized logical volume to host(s) coupled to the other DKC unit.
