AFAIK the intelligent BBU has memory onboard so you can swap the controller below in case of failure and turn the machine back on and write the cache back to the disks, that's also why they sell it for this much money. But nobody I know ever bought one or tried that. The dumb ones have been sufficient so far. -sm
