Either I'm so unlucky or it's common trouble for RS2BL040. Or a certain firmware. Can someone suggest?
2 Intel servers with the same configuration and software in a different contries from different supplyers
I just never use Intel raid controllers before and after. Only LSI or Adaptec. Never seen BBU fault. It was my first time.
I see the servers perfomance degrade this month. Just write cache switched off.
This is the BBU after 2-2.5 years of usage. Both the same:

So I try to do the learn cicle manualy without success.
May be it's possible to fix somehow?
