摘要： Methods and structure for enhancing connection pathways for storage controllers. An exemplary system includes a stack of Serial Attached Small Computer System Interface (SAS) expanders that are coupled to each other in series. The stack includes two end expanders that are endpoints of the stack which are directly coupled to only one other SAS expander of the stack, and a plurality of middle expanders that are each directly coupled to two other SAS expanders of the stack. The system further includes a plurality of storage devices that are coupled to the SAS expanders of the stack, and a SAS storage controller comprising multiple SAS ports that are each directly coupled to a different SAS expander of the stack, wherein at least one of the multiple SAS ports is directly coupled to a middle expander of the stack.
