Abstract: PROBLEM TO BE SOLVED: To obtain a shared loop multimedia data streaming server system by including a step for mutually connecting storage devices in a shared communication loop and a step for mutually connecting A/V srevers to the loop in the providing system. SOLUTION: A series storage architecture(SSA) or a fiber channel arbitrated loop(FC-AL) 68 is connected between controllers 56, 58, 60 and disk arrays 70, 72, 74, 76. The disk arrays 70, 72, 74, 76 are shared by all the controllers 56, 58, 60 in a cluster. In the case of storing titles of which number 15 restricted or required by the band width of a specific disk driving device, the same number of disk arrays 70, 72, 74, 76 is required. Consequently any controller can access a title T through the SSA or FC-AL loop 68.
