The primary issues of data warehouse architecture are higher cost, and poor performance. The reasons for these problems focus the architectural design. The solutions are proposed with the new modified data warehouse design through online data warehouse architecture with the recent technological support from cloud computing — storage area networks through the use of high speed fibre channel based storage devices with fibre channel switches. Finally the benefits and advantages of proposed design were discussed with the costand performance.

SCSI protocol is the protocol of choice for block storage management. Different transport mechanisms such as parallel SCSI, Fibre Channel, iSCSI and Infiniband can be used to transfer SCSI protocol data. Distance and connectivity limitations are the key drawbacks of parallel SCSI. Therefore, Fibre Channel, Infiniband and iSCSI (SCSI over TCP) are competing to emerge as the dominant next generation SCSI transport mechanism. By analyzing the different components of a network protocol, this paper evaluates whether Fibre Channel, Infiniband and iSCSI are (a) suitable for gigabit wire speeds (b) scalable across thousands of interconnected devices and (c) satisfy the needs of storage environments and storage protocols.
