How the Solution Protects Against Failures

The following tables provides a list of common failure points in a network and the corresponding protection that this high-availability solution provides.

Setup Requirements

To configure a high-availability solution using SVM appliances and SANbox SSPs, you must make sure that:

Each HBA sees only one SANbox SSP.

Each host sees both SANbox SSP in the high-availability solution, and no others.

Each StoreAge SVM appliance sees both SANbox SSPs.

Each StoreAge SVM appliance sees all storage ports.

If the storage includes dual-controller active/passive RAIDs, each SANbox SSP is cross-connected with the controllers, which means that each SANbox SSP must see both controllers in the RAID.
