right now, all I have is 2 dell servers in a rack with identical configs. (dual ethernet 
controllers and 1 separate controller for the heartbeat). Both are running 
linux-ha and are both connected to a dell powervault 220S storage array which is configured so 
that both hosts can access the drives concurrently (cluster mode). Im following the instructions 
at 
http://www.gyrate.org/archives/9  and am at step 17.. which says to configure CCS.

I guess we could get an APC power switch, but what would you folks suggest? i.e. what model for 
just a 2 cluster node (each server has 2 power supplies). Or is there a better way?
