SAN provide separate, dedicated high-speed pathways tailored specifically to storage access and storage management. Serverless backup uses the SCSI extended copy command to control data transfers between storage devices on the SAN without the backup data passing through the backup server.
Backup time is shortened and the load on the backup server is greatly reduced.
SAN technology, based on Fibre Channel, is being adopted by other storage management applications, including video serving, image and document archives, and storage migration. The SAN will deliver high transfer speeds, improved availability, and enhanced application performance. SAN architectures eliminate constraints of distance, scalability, and connectivity. Single and dual FCOs are supported to speed backup data flow.
