Channel load balancing leverages all front-end channels available on the SANsymphony-V nodes. The number of channels is only limited by the node resources. Whether it is a single SANsymphony-V node or a mirror of nodes, the application servers can take advantage of the channels because SANsymphony-V presents the virtual disks to all available front-end channels simultaneously.
Disk pool load balancing constantly analyzes data block location and tunes for optimal placement within the disk pool, achieving a striping effect. This auto-balancing ensures an even spread of all data blocks across the physical disks in the pool. This feature is especially important when modifying the number of physical disks in the disk pool as it avoids hot spots due to disk pool modification.
