Abstract:
1. A storage system comprising: a first plurality of digital data editing apparatuses; a first editing storage to which said first plurality of digital data editing apparatuses are coupled via fiber channel network, wherein the first editing storage provides a first logical volume and a second logical volume, said first logical volume stores digital data edited by said first plurality of digital data editing apparatuses, said second logical volume stores a backup data of a digital data of said first logical volume; a second plurality of digital data editing apparatuses; a second editing storage to which said second plurality of digital data editing apparatuses are coupled via fiber channel network, wherein the second editing storage provides a third logical volume and a fourth logical volume, said third logical volume stores digital data edited by said second plurality of digital data editing apparatuses, said fourth logical volume stores a backup data of a digital data of said third logical volume; a management storage to which said first plurality of digital data editing apparatuses, said first editing storage, said second plurality of digital data editing apparatuses, and said second editing storage are coupled via IP network, wherein the management storage maps said second logical volume of said first editing storage and said fourth logical volume of said second editing storage to a first virtual volume and a second virtual volume of said management storage, respectively; and a management server which manages said second logical volume of said first editing storage and said fourth logical volume of said second editing storage as said first virtual volume and said second virtual volume of said management storage, respectively, wherein said storage system has a first access path with which said first plurality of digital data editing apparatuses access said first logical volume via fiber channel network, a second access path with which said management server and said first plurality of digital data editing apparatuses and said second plurality of digital data editing apparatuses access said second logical volume via a cache memory of said management server and said first virtual volume, a third access path with which said second plurality of digital data editing apparatuses access said third logical volume via fiber channel network, a fourth access path with which said management server and said first plurality of digital data editing apparatuses and said second plurality of digital data editing apparatuses access said fourth logical volume via a cache memory of said management server and said second virtual volume.
