I was wondering if you can clarify. Isn't the case that all 24-port backplane utilize expander chips directly on the backplane to support their 24 ports or are they utilized only when something else, such as another 12-port backplane, is connected to one of the cascade ports in the back? What do you mean by a non-expander equipped LSI controller? BTW, I have three SuperMicro SC846 systems, which 24-port backplanes, and haven't any problem with them. -- Maurice Volaski, maurice.vola...@einstein.yu.edu Computing Support Dominick P.
