Above is an example demonstrating simple end-to-end connections with each SFP
port connected to a host adapter. Multiple logical drives, logical volumes, and logical
partitions can be created and each mapped to the corresponding host channel
ID/LUN combinations.
Note that EonPath multipath software or Linux Device Mapper is necessary for
controlling and optimizing the access to logical drives via multiple data paths.
