DRBD works just fine over a crossover piece of cat-5e. > Again, my understanding only, I could be wrong. Oh, it's a pure speculation on my part. Any resemblance to the actual RedHat is purely coincidental and all that. ;) -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
