Talk me down from this ledge :) Well, if you really don't want to jump, just break the switch between the redirectors and the BSDs into two crossover cables, so redir1 talks only to BSD1 and redir2 talks only to BSD2. You have equal immunity to single failures, no obscure failure modes, and no need for custom kernel stuff. I'd bet anything that actually observed availability would be better, not worse, because of the decreased chance for interesting bugs taking the whole complex down. -- Barney Wolff http://www.databus.com/bwresume.pdf I'm available by contract or FT, in the NYC metro area or via the 'Net.
