Today on a reboot, the server (ML-350 Gen9) says: "313-HP Smart Storage Battery 1 Failure - Battery Shutdown Event Code: 0x0400." ILO says its degraded. Googles advice is to replace it. Im aware its used to "preserve data" in case of a power failure. My question would be, is the "Smart Storage Battery" in an HP server really needed for "normal work", if I have an UPS attached to the server, that will shut it down normally anyway, in case of a power failure ? Or will there be other "problems" involved, when not replacing the Smart Storage Battery...or completely remove it ?
