A system for hierarchical data storage management and transparent data backup in a high speed, high volume Fibre Channel Arbitrated Loop environment comprising first (10) and second (26) Fibre Channel Arbitrated Loops, each coupling a Transaction Server (16) and backup HSM server (30) to high speed disk drives (12,14) and mirrored high speed disk drives (32,34) respectively. The two loops are coupled by a Bridge (28) compatible with the Fibre Channel Arbitrated Loop protocol which forwards write transactions directed to the mirrored disk drives (32,34) from the first loop (10) to the second (26) but keeps read transaction from the Transaction Server (16) to the high speed disk drives (12,14) on the first loop (10) isolated from backup and HSM transactions occurring on the second loop (26) between the backup HSM server (30), the mirrored disk drives (32,34) and backup storage devices (38,40) coupled to the backup HSM server (30). <IMAGE> |
