Abstract
Methods and systems for maintaining data connectivity in a secure data storage network are disclosed. In one aspect, a method includes assigning a volume to a primary secure storage appliance located in a secure data storage network the primary secure storage appliance selected from among a plurality of secure storage appliances located in the secure data storage network, the volume presented as a virtual disk to a client device and mapped to physical storage at each of a plurality of storage systems. The method further includes detecting at one of the plurality of secure storage appliances a failure of the primary secure storage appliance. The method also includes, upon detecting the failure of the primary secure storage appliance, reassigning the volume to a second secure storage appliance from among the plurality of secure storage appliances, thereby rendering the second secure storage appliance a new primary secure storage appliance.
