Load Balancing

Improve response and throughput

• Overcomes typical storage-related bottlenecks
• Spreads load on physical devices using different channels for different virtual disks
• Detects disk “hot spots” and transparently redistributes blocks across the pool
• Automatically bypasses failed or offline channels

Load balancing across the back-end channels into the physical storage pool complements caching to improve response and throughput. The host computers may also be doing host-based load balancing across their ports. Load balancing helps to overcome short-term bottlenecks that may develop when the queue to a given disk channel is overly taxed, or when one channel fails or is taken offline. SANsymphony-V regularly further fine tunes itself by redistributing disk blocks which may be overloading a specific disk drive.
