第1题：

While installing the equipment for a new two-node cluster， it is discovered that the disk subsystem  Rack has one connection to the power mains. The explanation given was that the disks are to be mirrored between the two disk drawers in the rack and that a failure in either of the disk drawers would simply result in half of the disk being lost.  What can be done to avoid a single point of failure？（）
