Can a RAID Battery test affect performance?
StruxureWare Central/Data Center Expert Enterprise server AP9475
The AP9475 StruxureWare Central / StruxureWare Data Center Expert server runs a RAID battery test every 90 days. The disk will go into Write Through Mode which will affect Server performance. This may cause the server to become sluggish during times of heavy activity.
This is a standard test that needs to run to validate the battery's condition.
