Given that data in the slog is only live for the 5-10 seconds I mentioned before, a datarate of 100MB/s suggests that you're going to have on the order of 1GB in use. Our experience with the Sun Storage 7000 Series has been that 8-10GB suffices. > Thus, the following logical question would be: what is the behavior of a > full SLOG?
