Hi Götz. I'm running Centos 6.2 on a Proliant DL380 G7 server connected to a HP Lefthand P4500 using multipath, and ALB(Adaptive Load Balancing) on the Lefthand box it self. Regarding, multipath vs bonding read this -> http://blog.open-e.com/bonding-versus-mpio-explained/ You will need to go through the storage manual for red hat enterprise 6 and read some chapters regarding configuring your options/needs for your scenario.
