Power Edition Storage Nodes

FIGURE 2-3shows an example of a Power Edition server using a storage node for backup and recover operations. Data hosted on each Power Edition storage node is backed up and recovered using immediate save and immediate recover technology. The metadata associated with backups is transferred over the network to the controlling Power Edition server, and the data is transferred directly to devices attached to the storage node.
Power Edition storage nodes enable you to design scalable configurations, since multiple devices can be attached to multiple storage nodes, and data transfer operations can run in parallel.

Power Edition Local Backup to a Silo

When you add a silo (specialized high-speed storage device) to the local backup scenario, performance increases because of the speed and number of devices in the silo. The silo requires another computer to be the silo server, which controls the robotics in the silo. The silo server cannot be the same computer as the Backup server.
