Abstract
A secure storage appliance is disclosed, along with methods of storing and reading data in a secure storage network. In one aspect, a method includes assigning a volume to a primary secure storage appliance located in a secure data storage network, the secure data storage network including a plurality of secure data paths between the primary secure storage appliance and a client device and a plurality of secure data paths between the secure storage appliance and a plurality of storage systems, the volume corresponding to physical storage at each of the plurality of storage systems. The method also includes detecting a connectivity problem on at least one of the secure data paths. The method further includes assessing whether to reassign the volume to a different secure storage appliance based upon the connectivity problem.
