NetApp E-Series

Description

  • Currently E-series systems used "Smart Batteries". 
    • This is a type of battery based on newer technologies that utilize different chemical compounds and provide complex support circuitry to provide estimated usage times
    • This type of battery can typically be exposed to a controlled discharge and recharge (learn cycle) which will restore the power capacity and extend the useful life of the battery
    • This type of battery can be used as long as it can be charged to a level sufficient to protect cache memory for a minimum required duration
  • When the Learn cycle finds issues during the process of discharge/charge of the battery, the system will trigger an Insufficient learned battery capacity alert and in the Major-Event.log an Incomplete battery learn cycle message will be displayed
