A bridge or hub is mandatory when using ethernet for the interconnect. HP does not support a straight through ethernet connection for a private ethernet interconnect

9、. For HP servers, third-party storage products, Cluster interconnects, Public networks, Switch options, Memory, Swap& CPU requirements consult the operating system or hardware vendor and see the RAC/HP certification matrix. Private network connection can be any of the following (see the RAC/HP certi

Each of the disk arrays are dual-ported to each node, meaning that each array has a cable directly connecting it to e
