Hi, I have a question about FBSD's disk cache mechanism. What happens when you run a SCSI-SCSI raid controller that contains it's own cache memory? The kernel has no way of knowing that some things are already cached out beyond the SCSI card, so I assume it would cache something that's already cached, right? How do you work around that? Is there some way of telling it "hey, don't be very aggressive with your disk caching"? Or is it such a low priority thing that memory isn't used for cache unless there's no other use for it?
