The 5300 NAS Controller Unit, A.K.A. CSM100, includes a battery backup to maintain the integrity of the controller’s data cache for up to 72 hours in the event of power loss to both power supplies.
Due to Oracle no longer being able to provide replacement batteries for the CSM100 disk trays, customers need to make a decision regarding how to proceed.
NAS systems with a Gateway license may not have effected storage attached and thus not be effected.
