Maintaining failure survivability in a storage system includes determining a save time corresponding to an amount of time needed to transfer system data from volatile memory to non-volatile memory, determining a threshold corresponding to time for batteries to run while transferring data from volatile memory to non-volatile memory after a power loss, and providing an indication in response to the save time being greater than the threshold. The system may include a plurality of directors and the save time and the threshold may be determined for each of the directors. Determining a threshold may include determining an amount of battery time provided by battery power following power loss and multiplying the amount of battery time by a factor less than one, such as 0.8.
