Abstract:
1. A method comprising: operating, by a storage system comprising an operating system, a non-volatile memory to temporarily store data, the storage system providing a client with access to data stored in a set of mass storage devices over a network, the non-volatile memory including a battery coupled to a charger, and a memory which is made non-volatile by the battery, wherein the storage system, through the operating system, analyzes a voltage level of the charger, and issue a command to operate the charger; detecting a voltage level of the battery to issue a command to turn on a charger that is coupled to the battery; issuing a command, by the storage system through the operating system, to turn the charger on to maintain a charge of the battery; determining a voltage level of the charger is greater than a threshold; issuing a command, by the storage system through the operating system, to turn the charger off in response to determining the voltage level of the charger is greater than the threshold.
