Abstract
A system and method proxies data access commands across a cluster interconnect between storage appliances in a cluster. Each storage appliance activates two ports for data access, a local port for data access requests directed to clients of the storage appliance and a proxy port for data access requests directed to the partner storage appliance. Clients utilizing multi-pathing software may send data access requests to either the local port of the storage appliance or the proxy port of the storage appliance. The system and method improve high availability especially during a loss of connectivity due to non-storage appliance hardware failure.
