Switched disk

Switched disk allow data that is stored in the independent disk pool to be switched between systems provides a level of data resiliency.

Characteristics for switched disks

• All data maintained in the independent disk pool can be switched and made available on backup system
• No data synchronization issues
• Single set of data minimizing cost for disk
• Potential single point of failure depending on the disk configuration
• Only supported between partitions in the same physical system
• Switchover and failover include vary on time before independent disk pool data available
• Can be used in conjunction with the other technologies
